GTKCrypto allows you to encrypt and sign files or text. Moreover, given a file, different types of hash can be computed and files can also be compared to check whether or not their content is the same. Supported cipher algorithms: AES, Twofish, Serpent and Camellia, all using 256 bits key and operating in either CBC or CTR mode. Supported hash algorithms: MD5, SHA-1, SHA-2, SHA-3, GOST, Whirlpool.
