Naeon Files

August 2024

v2.3 - 2024-08-24

Added

• Formal Security Analysis.

Changed

• Updated FAQ.

November 2023

v2.2 - 2023-11-01

Added

• Program startup message to display logging status and log directory if logging is enabled.
• Package pv (Pipe Viewer) to the environment prerequisites.
• Enhanced progress indicator using 'pv' to display a percentage-based progress bar along with an estimated time of arrival (ETA).
• Introducing the STATCMD variable, which dynamically sets the appropriate command for system-specific environment detection, ensuring seamless compatibility across different platforms.
• Improved readability of the display of extracted files during backup and restore by separating the files by a newline both before and after.
• ADD_DESCRIPTION_TO_LOG to naeon.conf configuration file. If set to yes, AND if logging is enabled, the backup description will be added to the log entry of the backup process.
• ISSUER and ISSUER_NOTES to metadata file in info directory (if enabled). Set to "(empty)" in case they have not been declared in the configuration file.
• Private chunk split count (>= 1) as well as the paper wallet option chosen (yes/no) to metadata file in info directory.
• In restore mode, when no private chunk tar balls are found in the private directory but a paper wallet is present, private chunk(s) are now automatically extracted from these (uue) files.
• Added optional CSV export functionality to record key backup information for easier tracking and analysis. Enabled when CSV directory is set in naeon.yaml (NAEON_CSV_DIR).
• In restore mode, input validation to ensure project ID starts with '2', being the first digit of any Naeon project ID.

Changed

• Enhanced passphrase generation method, transitioning from '< /dev/urandom' to 'openssl rand -base64 128’ for improved entropy hence security.
• File format of the Naeon configuration file from unstructured to YAML format.
• Name of the configuration file from "naeon.conf" to "naeon.yaml".
• Implemented a more efficient and concise method for initializing configuration variables with their default values, enhancing maintainability and readability.
• Function "read_config_file" to make it compatible with macOS when using the sed command for removing leading spaces in variables read from the YAML configuration file.
• "Less is more": Replaced 'more' command with 'less' to provide a more user-friendly and interactive text screen display, especially for help and information texts.
• Enhanced the clarity and consistency of comments within the configuration file.
• Reduced redundancy by consolidating the logic for creating paper wallets (uuencoded ASCII versions of Private Chunks).
• Optimized code for conditional description logging.

Fixed

• In case the project directory wasn't set in naeon.yaml, the default (current) directory wasn't set which resulted in an error. Now correctly falling back to the current directory.
• Improved the overall code structure and formatting of the metadata file generation code for a more efficient and organized codebase.
• On systems where the pv command is not available, the function 'dotted_timer' will be used to indicate the progress of time consuming processes.
• Error in the restore section of the help text. It previously stated that the project ID should be preceded by 'naeon-', whereas it should start with one or more digits of the project ID.
• Incorporated enhanced file checking logic to gracefully handle cases where a tar file is empty during backup, ergo when no files are present to be backed up.
• When backing up from an input text file using the -l or --list option, temporary files were not automatically cleared if the input file was invalid or included wildcards.
• In backup mode, addressed an argument parsing issue, preventing the passage of conflicting parameters.
• In backup mode, the project directory wasn't removed after exiting if the tar file didn't contain any files or if an error occurred during temporary directory creation.
• In restore mode, in case of a public chunk (hash) mismatch, temporary files were not deleted after program exit.

Removed

• Redundant, outdated code sections, that were replaced with more optimized solutions.

October 2023

v2.1 - 2023-10-01

Added

• Extra cyber security related quotes, which are displayed occasionally, at program completion.
• Error logging for all instances where an 'exit 1' error code is encountered.
• Error checking for the writability of the log directory.
• More extensive help texts where needed.

Changed

• In the event of an error while moving temporary files, Naeon will now provide a more informative error message, log the error, and invoke a proper exit routine.

Fixed

• Modified the 'dotted_timer' function to remove the usage of the '-p' parameter with the 'ps' command, ensuring compatibility with all 'ps' command implementations.

Removed

• Redundant code blocks.

February 2023

Added

• Package ncurses to the environment prerequisites.
• Naeon extension to metadata file in info directory.

• Rewrite of the clode blocks in the restore loop that compare checksums in private and public directories, optimized for speed, efficiency, and readability.
• Rewrite of the clode block in the restore loop that does the integrity check on chunks based on their SHA512 checksums, optimized for speed, efficiency, and readability.

Fixed

• In restore mode, the private directory was not always cleaned up when encountering a fatal error.
• Proper exit routine when invoked with option --version.
• Directly jump to exit routine when started in backup or restore mode without any further arguments.

Changed

• In backup mode, remove compressed inputfile immediately after the encryption process (instead of at the end of the program) in order to save space.
• In backup mode, remove encrypted inputfile immediately after splitting it up into private and public chunks (instead of at the end of the program) in order to save space.
• Create detailed file list directly after encryption process.

• Location of info directory: from under private directory under the name 'info', to project directory under the name <Project ID>-info.
• Moved the location of the Paper Wallet uuencoded versions of the private folder file(s) from the info directory to the private directory.

Fixed

• In backup mode, in case PAPER_WALLET was set to yes and SPLIT_PRIVATE_FOLDER_INTO_PARTS was set to >1, only one uuencoded file was generated, instead of the actual number of splits.

Removed

• List of public chunks in info directory (in order to enhance security).
• List of private chunks in info directory (in order to enhance security).
• STORE_PROJECTDESC_SEPARATELY in naeon.conf.
• Textfile in info directory containing the project's description (moved to a new metadata textfile).
• Textfile in info directory containing the project's Naeon version (moved to a new metadata textfile).

November 2022

v1.2.4 - 2022-11-01

Added

• Extra cyber security related quotes, which are displayed occasionally, at program completion.

Changed

• In case PAPER_WALLET is set to 'yes' in naeon.conf, now the private chunk tarball(s) will be uuencoded, instead of the private chunk itself and the Master Key XML.

Fixed

• No call to exit routine in case Naeon project directory was missing.
• No call to exit routine in case Naeon temporary directory was missing.
• In case PAPER_WALLET is set to 'yes' in naeon.conf, the wrong extension was passed into the generated uuencoded file.

• Progress indicator during data restore process in case silent mode is set.

Changed

• Naming convention of file list containing private chunks now in line with that of public chunks: naeon-<yyyyymmddhhmmss>-PrivateChunks.txt (info directory).
• Renamed private chunks from <Project ID>-private-<xxx>-of-<yyy> to <Project ID>-private-<xxx> thus removing information regarding the total nr of private chunks in the filenames.

Fixed

• Wrong mention of default embargo timestamp in naeon.conf. Old: "default is 20200101000000", new: "default is current time".
• Wrong mention of default temporary directory in naeon.conf. Old: "current directory", new: "/tmp".

Removed

• Path names from file list in info directory containing private chunks and their sha512 checksums. Now in line with that of public chunks: sha512sum + space + filename.

Fixed

• Incompleteness in the error message in case the encryption key could not be generated.
• Check on existence of Naeon project and tmp directory didn't work as intended on macOS.
• When executed in attended restore mode, project wasn't immediately skipped in case of mismatch between number of public chunks in XML and in public (restore) directory.
• In case of a chunk-number of hash mismatch in restore mode, the restored .naeon and .XML files were not removed from the private directory before skipping to a next project ID, if any.

May 2022

v1.2.1 - 2022-05-01

Added

• Info directory 'info' under private directory, in which all private files will be stored that are not archives themselves.
• Naeon will now look for the naeon.conf configuration file in the $HOME/.config/naeon directory first, and (if not there) in the program directory.
• Some speed improvement by removing unnecessary lines of code.
• Preventing gpg from caching passphrase by adding the option --no-symkey-cache to the encryption command.

• Additional checks on passing conflicting command line arguments in restore mode.
• Extra comments where needed to make the code better readable.

Changed

• Moved compressed restores to: project dir/project ID-restored/project ID-compressed
• Moved decompressed restores to: project dir/project ID-restored/project ID-decompressed
• Moved the creation of temporary directories from working directory to /tmp.

• Replaced 'naeon' with 'Naeon'.
• Old program logo replaced by (a Unicode representation of) the official new logo as used on the website.
• In restore mode, it is no longer required to submit project IDs starting with "naeon-". With or without, it is both okay and will be handled correctly.

Fixed

Added

• Option in configuration file to split the private folder into n parts in order to be able to spread it over multiple locations.
• Option in configuration file to disable the creation of uuencoded versions of Master Key XML and private chunk (naeon's paper wallet).

Fixed

July 2021

v1.0.3 - 2021-07-04

Changed

• Updated help text.

Fixed

• Backup mode: help parameter opened the wrong text (README.md instead of USAGE.md).

April 2021

v1.0.2 - 2021-04-25

Added

• Function "dotted_timer" showing process indicator.
• Backup mode: now creating a list of Public Chunks, saved in the private directory under the name 'naeon-yyyymmddhhmmss-PublicChunks.txt'.

Changed

• Moved cleanup function from backup- and restore code block to main code block.
• Some minor improvements in the layout of the console output.

March 2021

v1.0.1 - 2021-03-06

Added

• In backup mode, after adding append block, check if the size of prepend, data, and append block add up to the reported total size.
• Check if all public chunks are similar in size. If the unlikely case this happens (usually with very big archives), exit the program.
• Notification of successful decryption.

Changed

• Default self-destruct timestamp (when not set in naeon.conf) from 99990101010101 to 99991231235959.

February 2021

v1.0 - 2021-02-20

Added

• Check on the version of tar: this should be 'GNU tar' as bsdtar (standard on macOS nowadays) displays unwanted behaviour when used icw relative pathnames.
• GNU tar to the list of prerequisites.
• Extra information in the explanatory text describing the proceedings after a backup has been made.
• Better reporting in restore mode - now mentioning removing prepend and append block.
• Function check_datestring checks validity of Embargo Timestamp and Selfdestruct Timestamp in naeon.conf.

• Check if Embargo Timestamp precedes Selfdestruct Timestamp and if not, exit.

Changed

• Text "Found:" into "Selected:" since it concerns submitted project IDs, which does not necessarily mean valid (read: found) ones.
• Tidied up code, changelog.
• Moved the tag <Naeon_version> to the top of the Master Key XML.

v0.9 - 2021-02-09

Added

• Restore mode: use of wildcards (f.e.: naeon --restore naeon-2021* or naeon --restore 20210202153948 20210202180839 20210202191220 -u -n).
• Backup mode: now reporting "Creating compressed archive" when the tarball is being built. Since this can take some time, user might otherwise wonder what's happening.
• Restore mode: clean exit with error message in case an invalid key was used for decryption (should normally never happen with the right, non-corrupted Master Key XML).
• Restore mode: now reporting "Processing naeon project .. of .." for each project (to be) restored.
• Clean exit with error message in case encryption of the input file failed.
• Option '--batch' added to the encryption command since gpg requires it when used in combination with the '--passphrase' option.
• All fatal errors now marked in red for better visual distinction between fatal errors and standard output.
• At the start of the program in restore mode, naeon now displays "Found: " followed by the selected project ID(s).

Changed

• Restore mode: better, more informative error message in case the hash of private and/or public chunks do not match those in the XML.
• Passphrase 128 characters alphameric.
• Renamed the tag <Key> in the Master Key XML to <Passphrase> which is what it in fact is: a passphrase used by the gpg command to generate the 256bit key.
• Due to the renaming of the <Key> tag in the Master Key XML, the restore mode in this version is not backwards compatible with prior versions.
• Moved major part of initializing block to before the preliminary checks.
• Moved the passphrase tag in the Master Key XML to just after the <Encryption_command> tag.
• The encryption key (passphrase) is no longer (temporarily) saved to disk, but (temporarily) kept in memory instead, and immediately cleared after use.

Fixed

• Restore mode: now skipping submitted non-existing project IDs, instead of exiting the program.
• Restore mode: when restoring more than one project ID, the naenon header is now shown only once.
• Restore mode: instead of crashing, naeon now skips to the next project ID in case a submitted project ID is missing directories and/or required files.
• Backup mode: "Creating compressed archive" was displayed one time too many.
• Created more consistency in the (position of) displayed messages in batch restore mode.
• Restore mode: improved error handling in cases where private and/or public chunks are missing, checksums do not match, or decryption was unsuccessful.
• Program exited unintentionally in restore mode when using the --unattended option.

Removed

• Command 'file' from prerequisites. On systems where it is not installed, the validity check on plaintext file lists is skipped when backing up with parameter '--list'.

v0.8 - 2021-02-02

Added

• Error log in backup mode, saved in the private directory under the name 'naeon-yyyymmddhhmmss-ErrorLog.txt'.
• Encryption program version to the Master Key XML.
• Restore mode now accepts input parameter, being the naeon project ID (yyyymmddhhmmss) with or without prefix 'neon-'. No parameter needed in case one project exists.
• libseccomp to requirements. In restore mode, the command 'file' (part of libseccomp) is needed in order to determine the file type of input file lists.
• Version numbers of required software packages.

Changed

• Renamed directories for compressed and decompressed (restored) data to their more logical names 'naeon-<yyyymmddhhmmss>-(de)compressed'.
• Variable name "NO_DECOMPRESS" into "DECOMPRESS".
• Options '--file' and '--dir' merged into '--backup'.
• Renamed folders to: naeon-<yyyymmddhhmmss>-decompressed, -compressed, -private, -public.
• In Error Log, ignore tar messages 'tar: Removing leading '/' from member names'.
• In restore mode, forward slashes removed from input parameter, so file completion will also work (when input parameter ends with a forward slash).
• In restore mode, the integrity check now displays a file counter instead of the hashes. Only in case of errors, the hash of the file in question will be displayed.
• 'tail -c' and 'head -c' replaced by 'tail --bytes' and 'head --bytes' for reasons of portability.
• In backup mode '--list', error message adjusted when input file doesn't pass the plaintext check.
• Moved the declaration of required software packages from backup and restore blocks to init block.

Fixed

• Removed rendundant message "Restored decompressed data are stored in" as this was already mentioned 3 lines before.
• Wildcards can now be used in all modes (Tim vd A).
• Some sort of non posix compliancy caused 'echo' icw the '-ne' parameter not to be working on macOS systems. Switched to printf in these instances.

January 2021

v0.7 - 2021-01-25

Added

• Support for wildcards on command line (options --file, --dir).
• Relative pathnames for files, directories, and file list now supported.
• Clean exit with status 1 when no input parameters are supplied.
• After backup, a list of files is now kept in the private directory, named 'naeon_filelist_<yyyymmddhhmmss>.txt'.

Changed

• In backup mode, creation of temporary directory moved from 'Generating encrytpion key' to 'Files & directories'.
• Files, directories and file lists should now be entered between double quotes.
• Moved private, public, and restored directory into a new 'project' directory, named 'naeon-<yyyymmddhhmmss>'.
• Naeon file list in public directory contains a detailed listing of all files in archive, with timestamp of files and their sizes.

Fixed

• Failed to backup a file which contains spaces in the name in 'backup from file' mode.
• Sending tar message 'Removing leading '/' from member names' to /dev/null since restores are done in a separate directory anyway.
• Temporary tar files were not stored in the temporary directory.
• Help texts updated.
• On macOS systems, the tar command doesn't allow to create a new tarball with the -uvf option.
• In backup mode, when minimum file size was reached, program exited without removing empty private and public directories.
• Now performing a check on empty private / public directories in restore mode.
• When option '--no_decompress' was chosen and therefore no restored directory was created, "Restored data are stored in ..." was displayed.

v0.6 - 2021-01-21

Added

• Check on unsupported input fags / arguments in parsing routine.
• All output goes to the working directory (by default this is the current directory).
• Working directory can be set in the configuration file.
• Error handling routine for non-successful creation of directories.
• New: '--list' for backup from plaintext file containing a file list: one file per line, with full pathname, no wildcards.
• Check on use of relative pathnames (tar doesn't like them when restoring, for security reasons).

Changed

• In restore mode, no creation of directory 'restored-##########' if it already exists.
• In restore mode, when option '--keep' is chosen, compressed archive is stored in the 'restored-##########' instead of current directory.

Fixed

• Wrong use of boolean in cleaning up compressed archive routine.
• Now checking on conflicting input parameters.
• Crashed when run from a pathname containing one or more spaces.

Removed

• Redundant check on zero input arguments, as the new parsing routine takes care of that as well.

• Function 'show_usage' in init mode, called when no valid arguments were specified.

Changed

• Improved, less cryptic, error message on unsuccessful attempt to create compressed archive.
• Moved startup message 'Starting naeon in .. mode' to the end of intro text.
• After restore, setting the (UTC) timestamp of the backup instead of that of input file.

• On several occasions where the program exited with exit code 1, the compressed archive wasn't cleaned up.
• User input from configuration file sanitized in order to avoid non-alphanumeric characters pass through to the Master_Key.xml file.

Removed

• Inputfile timestamp variable, as the inputfile is no longer necessarily a single file but can also be a directory or group of files.
• Tag <Inputfile_timestamp> from Master_Key.XML.

v0.3 - 2021-01-14

Added

• readme.txt.
• Warranty text in backup as well as restore mode.
• 'Haiku' (a BeOS clone) added to the list of supported platforms (linux, macOS, BSD).

• This CHANGELOG file to hopefully serve as an evolving example of a standardized open source project NAEON.

Changed

• Text color yellow (tput setaf 226) changed into green (tput setaf 10) for better readability on white backgrounds.

Fixed

• Misspelling of 'macOS'.
• Error 'Argument list too long' when moving large numbers of Public Chunks to public directory on low memory systems.
• Missing requirements in backup mode.
• Variable 'unattended mode' was not set in restore mode.

v0.2 - 2021-01-10

Added

• Minimum size for inputfile (100,000 bytes) in order to prevent encryption key ending up in public chunk.
• Reporting on updates in size of encrypted file after: creation, insertion of prepend block, and adding append block.
• Handling the unlikely occurrence of a zero-size append block.
• Better, more structured reporting on the sizes of the chunks and their distribution.
• Tag in XML: 'Naeon_version' containing the current naeon version number.

Changed

• Replaced 'exit 0' by 'exit 1' when program is terminated unsuccessfully.
• Size of prepend block: from a random value between 1,000-500,000 bytes, to a random value between 1-10,000 bytes.

Fixed

• On BSD and macOS: when splitting the encrypted file into private and public chunks, 'bc' was not set to arithmetic mode.
• On BSD and macOS: splitting encrypted file into > 676 (26^2) parts ( x[a-z][a-z] ) resulted into error "split: too many files". Fixed: x[a-z][a-z][a-z] now maxes out on 17,576 (26^3) parts.
• Find command adjusted - now looking only for split-files x??? and no more for x?? and x?????.

v0.1 - 2021-01-08

• Merged ecbu (backup program) and ecre (restore program) into 'naeon'.
• First integrated, fully functioning, encrypted backup & restore version of this program. Initial public beta version.
