Base64 Decode

Base64 is a binary-to-text encoding scheme whereby an arbitrary sequence of bytes is converted into a sequence of printable ASCII characters. The protocols POP3 and SMTP use this scheme to be able to transfer pictures in a readable text format,so you might get the point why this is not suitable to apply when it comes to encrypting data that should not, under any circumstances, be read by other persons who you don't trust.
