Open Source ChromeOS Encryption Software

Encrypt or decrypt 12, 15, 18, 21 or 24 BIP39 codewords array (so-called "seed phrase") using exclusive OR (XOR)/Vernam cipher (a.k.a. One Time Pad). If not input by a user, an encryption key is automatically generated at random. Encryption with such a key preserves integrity of BIP-39 checksums of all keys (that's distinct while also compatible with SeedXOR implementation).

MicroZip is a powerful file compression and encryption utility for mobile phones which allows you to create and extract compressed archives in multiple formats and encrypt sensitive information with powerful AES-256 encryption. MicroZip can create and extract ZIP,TAR,TGZ,TBZ2 archives and extract many other formats as JAR,GZ,BZ2,TBZ,WAR,BZIP2,GZIP,Z,TAZ,CBZ etc. MicroZip allows you to extract selected files without extracting the whole ZIP archive. MicroZip also supports encrypted ZIP archives with both classic ZIP encryption and AES 256 encryption algorithm.

QPass is easy to use, open source password manager application with built-in password generator. You can store in it's database such data as passwords and logins which will be encrypted using AES-256 with PBKDF2(number of iterations set by user). Each entry can include additional information about entry such as name, url adress and description.

ShredBitz is a free and simple file shredder tool that can wipe selected files from any hard disk drive. ShredBitz is written in the java programming language and uses a custom written algorithm for shredding. ShredBitz is a very powerful tool.

Emojis of Death is a down and dirty browser app, written in HTML. It's HTML, so it will work on anything a web browser can run on. It's purpose is to hide text strings in emojis, which you can then text or email. An encoded emoji can hold quite a bit of text. The receiver will need Emojis of Death as well, to decode the emoji. The file's small size makes it perfect for your phone. Some email and text services don't work with this, so try it.

This tool can create one-time-password values based on HOTP (RFC 4226: HOTP: An HMAC-Based One-Time Password Algorithm), TOTP (RFC 6238: TOTP: Time-Based One-Time Password Algorithm) and OCRA (RFC 6287: OCRA: OATH Challenge-Response Algorithm) standards, and also supports client side of OAuth protocols (1.0a, 2.0).

HashSum is a .NET port from GNU's md5sum and sha1sum. It supports: hash algorithm selection between MD5 and SHA1 (more could be added later) and compatibility between HashSum and GNU's checksum file format

Address to hash160 is an efficient multi-threaded tool designed to decode various cryptocurrency addresses (such as Bitcoin BTC,Bitcoin Cash BCH, Litecoin LTC, Bitcoin Gold BTG, etc.) to extract hash160 values. It is often used in research such as brainflayer, keyhunt, BitCrack, ecloop, keyhunt cuda, etc.

Amnesia is a design-rich 'host-proof' web application that encrypts and remembers all sorts of personal information from passwords to private notes. Project now hosted at Google Code: https://code.google.com/p/amnesia-app/

AresCode2008 is system to crypt files. System is used new cryptography algorithm.

This is a non-causal non-linear encryption system that cannot be cracked by the von-neuman architectures available today

Most of today's cryptographic standards will be broken with tomorrow's computational power. Azrar is a user-friendly tool for the encryption/decryption of single files - preferably compressed archives - addressing long-term data secrecy. Thus, Azrar provides the possibility to use webspace for secure data transfer between two communication/transfer partners (encryption only, network transfer not yet included in current version). Data in encrypted files are secret/private indefinitely. To achieve long-term data secrecy, Azrar differs from other approaches in terms of not to rely on effective computational deficiencies. It combines a one-time pad with a stream cipher method using the strong cryptographic hash function (family) Skein. Azrar fulfills business requirements for secure data transfer and supports several operating systems natively. It does not use a runtime environment.

BEDBUG is a small, fast, cryptographically secure pseudo-random number generator (CSPRNG) and stream cipher. It exhibits uniform distribution, mixes rapidly (with worst-case avalanche better than 16-bits), has no detected bias, and comes in three variants: BEDBUG128, with an internal state array of 128+3 32-bit words; BEDBUG256, with an internal state of 256+3 words; and BEDBUG512 with a 512+3-word state. The former permit seeding with a key of up to 4096 or 8192 bits, the latter with a 16384-bit key. The BEDBUG generator itself is a mere 5 lines of code: Three rotations; two pseudo-random lookups. The default BEDBUG configuration alternates the rotation constants unpredictably. These four sets of three values differ between BEDBUG128, BEDBUG256 and BEDBUG512 and were selected, tuned and tested in each case for optimal avalanche, which is never less than 16.5 bits. BEDBUG has passed stringent industry-standard tests for randomness, including NIST and DIEHARD.

A command-line program to encrypt/decrypt a message using a random reciprocal bigram table and write a bigram table to a text file. Executing the program without any command-line arguments starts bigram in message encryption/decryption mode. The program prompts for a password or passphrase and a message to encrypt/ decrypt. After the message is entered the ciphertext is displayed. Executing the program with command-line arguments causes bigram to generate a random bigram table to print to screen or save to disk depending on whether the -f filename argument was given. If the -p passphrase argument is given a specific table is generated and is repeatable each time the same passphrase is given. This program was written to supplement the Enigma Simulator by Dirk Rijmenants. http://users.telenet.be/d.rijmenants/en/enigmasim.htm Enigma message procedures: http://users.telenet.be/d.rijmenants/en/enigmaproc.htm
