[ACCEPTED]-Best way to separate two base64 strings-base64
All you have to do is to use a separator 4 which is not a valid Base64 character. Comma is 3 not a base64 character so you can use.
Base64 2 characters are
[0-9a-zA-Z/=+] (all numbers, uppercase, lowercase, forward 1 slash plus and equal sign).
This seems like a good solution. The comma 1 cannot be part of a base64 index table so it is a safe separator.
