Open Source ChromeOS Decryption Software

BitShade is a graphic utility to encrypt/decrypt with AES, base64 encode/decode, calculate the SHA checksum. It is cross platform, written in Java.

FMSec (File Manager SECurity) is a set of extensions to file managers that enable some security-related operations to be easily performed. The operations are: - encryption and decryption using OpenSSL (https://www.openssl.org/), - safe removing (shredding) files and directories (recursively), - mounting and unmounting TrueCrypt and VeraCrypt (https://www.veracrypt.fr/en/) volumes, - wiping the free space on a filesystem using WipeFreeSpace (https://wipefreespace.sourceforge.io/), - running programs with LibSecRm (https://libsecrm.sourceforge.io) preloaded, - running programs with LibHideIP (https://libhideip.sourceforge.io) preloaded, - running programs with LibNetBlock (https://libnetblock.sourceforge.io) preloaded. See the project homepage https://fmsec.sourceforge.io and the project Wiki in the menu above.

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/

AnLib is a PHP library of useful functions and classes to help you build and deploy PHP applications swiftly and easily.

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.

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

Cryptic is a cryptographic applications suite for encryption/decryption of data, calculating cryptographic hashes or message digests and securing user passwords using a master password in a password safe.

Cryptomni is a program which can encrypt and decrypt files using the one-time pad cipher. If a key is truly random, kept secret, and never reused, this encryption algorithm can be proven to be unbreakable.

Enfomi is a cross-platform standalone password-based encryption/decryption program that supports 27 algorithm variants (including AES 256bit). Archives can be self-decrypting, thus making it perfect for mobile applications.

ROT-13 Encryptor/Decryptor. More functionality will be added as different updates are released.

The Moonbounce API is a set of high level objects that encapsulate pieces of the Bouncycastle lightweight crypto API. Moonbounce significantly simplifies RSA key generation, signing, encryption/decryption and verification of both byte arrays and files.

OhCrypt lets you easily encrypt and decrypt files using some of the most popular algorithms, like AES, Blowfish and Serpent. With OhCrypt, you can secure your data with a password-based encryption algorithm through a clean and simple interface. It demonstrates state of the art of cryptology techniques, such as password hashing and salt. Ohcrypt also features self-extractable and self-destructive encrypted files

Open En/decryption software. Current version allows for 2 keys, 1 at 32 bytes, and 1 at 20 bytes. Supports ASCII and Binary files in a multiple-executable polylithic architecture.

Flash/PHP adaptation of the XTEA encryption algorithm. Allows encryption/decryption of sensitive data using 128-bit key. May be used for network data (HTTP) or offline for implementations like secure CD-ROM projects.

An e-mail client with address book

jCryptor is a Java-based cryptographic tool used for any kind of file. It implements the Data Encryption Standard (DES) to encrypt and decrypt files. The Graphical user interface is based on the java-swing components. It is fast and efficcient

Rijndog is an easy to use file encryption/decryption package making use of the Rijndael AES algorithm.

SLEncrypt is a python module for encryption with 11 ciphers at the moment, including ADFGVX, Autokey, Caesar/ROT13, Vigenere, XOR and a lot more. It contains functions allowing you to easily encrypt/decrypt files. The code is about 95% PEP 8 compilant.
