Technical details

AES encryption is done using the Rijndael algorithm and a 256 bits key. The result is converted to Base64 characters. For RC4 and Blowfish the input is also converted to Base64. In all cases, the key used is actually the sha-256 result of the pass phrase you write. In the case of hashes, if the Salt option is selected, the salt generated is a random string of 64 characters which is prepended to the input text.
