Aria FE is a symmetric, no nonsense file encryption tool with a [very] minimal graphic interface. AES, Aria, Camellia, ChaCha20, and SM4 ciphers are supported.
FTC cascades choice of Aria-256, AES-256, Camellia-256, SM4, or ChaCha20 for file and text encryption, the keystream generation is extremely robust
I don't make cute interfaces, it just works.
An original bruteforce-based encryption/decryption system. BBE was originally conceived to chat with encrypted text on IRC. mIRC and X-Chat support BBE via script addon. BBE can also encrypt MIME encoded files. Blowfish encryption is currently supported.
