Open Source Linux Cryptography Software

UPDATE 2024: Get a new version here: https://github.com/ivoras/EncryptedNotepad2 "Encrypted Notepad" does only one thing, but aims to do it perfectly - a Notepad-like simple text editor where files are saved (and later loaded) encrypted with industrial strength algorithms. Available both for the desktop (as a Java application) and on Android. Unencrypted data is never stored on-disk. Source is released (on SourceForge) under the BSD license.

PCSecrets is a PC application that holds secret text data - protected by a master password and strong encryption. Use it as a password manager or just somewhere to hold any text data securely in one place. It can hold a second, hidden set of secrets that is undetectable and plausibly deniable. The program is also a PC counterpart of the Secrets for Android app. It uses the same data structure and provides synchronization that allows easy transfer of secrets between the two. For those who find the personal computer environment more comfortable for data entry and editing (i.e. a real keyboard), PCSecrets provides an alternative way to manage your secrets. Sync is also effectively a form of backup. To enable the sync feature with Secrets for Android, you need to install the PCSecrets Sync app, downloadable from SourceForge or Google Play. PCSecrets import plus PCSecrets Sync provides a route to importing secret data into Secrets for Android that would not otherwise be possible.

The Arcanum Editor is a small but powerful tool to encrypt and decrypt messages. The program also comes with it's own format CTXT. This format is based on XML and allows you to save texts with the Advanced Encryption Standard.

TextConverter is a graphical text editor allowing the user to encrypt/decrypt the textual contents displayed on the screen using a 128-bit AES (Advanced Encryption Standard) cipher.

Mailcrypt is an Emacs Lisp package which provides a simple interface to public key cryptography with PGP [and now GnuPG!]. Mailcrypt makes strong cryptography a fully integrated part of your normal mail and news handling environment

Generate RSA key pairs of arbitrary length; convert text between formats or use keys to transform/crypt text. Supports decimal, hexadecimal, base64 and text input and output. Entirely ANSI C++; no external dependencies.

AESTextCrypt is an easy-to-use open source tool for text encryption and decryption. Primarily intended for use with email, use it wherever you need to protect text from prying eyes. The encrypted text can be copy/pasted into any text-handling application (e.g. email) instead of plain text. Convenience buttons are provided for clipboard operations. AESTextCrypt uses AES-256 bit encryption which is the strongest available encryption scheme. It also employs bcrypt, which implements key-stretching and an adaptive key setup phase, the complexity (number of rounds) of which is automatically set to match the processing power of the encrypting computer. This makes it highly resistant to dictionary attack. AESTextCrypt is written in Java, so can be run on all desktop platforms - Windows, Mac and Linux.

This is free Java desktop application to keep your note in safe from others using the Encrypting Decrypting symmetric key algorithm, it's easy to transfer your note form source to another in confidential manner.

Imagine being able to send an encrypted message as a single file to someone working on any Operating System, without them having to install any software to decrypt it. Just send them an Inkjar. Or you can store your own passwords on a usb key anywhere.

A Secure Diary Program written in Java and using the bouncycastle JCE Cryptograpic library. It uses a combination of BlowFish and TripleDES (XORed) to encrypt Diary entries.

It is a simple password manager for your PC and Smartphone. It works like a text editor and uses a strong cryptography algorithm to generate the end file.

P.I.G.: Privacy In Gedit, a plugin for gedit, encode and decode text to base64.

Application scans a given textual string in 146 pen on paper possible combinations- horizontal, vertical, diagonal, reverse, join top, join bottom, groups(2/3/4..), edges & in quadrant dimensions of your choice

Un programa para cambiar el orden de las palabras en una frase o las letras de una palabra u otros algoritmos. Su principal objetivo es cambiar las frases para hacerlas mas ilegibles o para aparentar ser más friki en tus conversaciones o por diversi

Line command cleaner/converter files.

Twinkle is an open source text editor that saves the documents in an encrypted form.

jCryptPad stores text informationen hierarchical, e.g. passwords, important texts etc. The data is saved in a encrypted xml file. Encryption is done with the AES algorithm. Additionally a password generator and a text encryption editor is also included.

Help to convert text into secret codes , so that you can mail,chat and transfer text securely to prevent hacking. How to use : Step one - Open Endico 14 Step two - Decide what to do (Text Encode/Text Decode) Step three - If You Selected Text Encode -> Then Type/Copy/Open .txt file to convert. Step four - Copy the converted text into clipboard to chat,mail,print process etc. Step five - If you want to Decode the code the again follow step two. Step six - Congratulations! you done it . ------------------------------------------------------------------------------------------------- Advantages and Applications 1. Fast and East TEXT encoding. 2. Fast and Easy Code decoding. 3. Easy User Interface & 24x7 Support. 4. Low system requirements. 6. Easy to share outputs. Note : Use same application to decode the data . -------------------------------------------------------------------------------------------------- (C) Logicwoods Ind
