    AESTextCrypt

    AESTextCrypt

    Encrypt and decrypt text using AES 256 bit encryption

    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.
