Base-64 is not an encryption protocol. It sends data in 7-bit ASCII data format. MIME, web servers, and other Internet servers and clients use Base-64 coding.

 

The provided Base64Enc() function is an encoding function. You need it when you want to send attachments with POP3 for example.

The target string will use 1 additional byte for every 3 bytes.

So make sure the target string is dimensioned longer then the original string.
