Alarm bells are ringing: Base64 is NOT an encryption scheme. It is a 
useful way for encoding binary content as ascii - for example, it's used 
to send binary attachments by email - but it provides absolutely no 
additional security as anyone who knows the algorithm can decode it. I 
sincerely hope this merchant account has more "security" than just base64!

Best regards,
