Re: Base64 Encoding

[Mihael Schmidt <mihael@xxxxxxxxxxxxxx>]

Base64 encoding is character set dependent. If you encode your data with 
an encoder for some EBCDIC CCSID and your online encoder expects it to 
be UTF8 it won't work.

The ILEastic project has a Base64 encoder for UTF8. This will definitely 
work better with the online encoders. I have successfully used it for 
JWT signing where you also have to Base64 encode the parts of the JWT token.

Best regards
