Feature Request: URL Safe

[z2z]

Add something like Base64url

Ref: https://docs.microsoft.com/en-us/dotnet/api/microsoft.identitymodel.tokens.base64urlencoder.encode?view=azure-dotnet#Microsoft_IdentityModel_Tokens_Base64UrlEncoder_Encode_System_String_

"The following functions perform base64url encoding which differs from regular base64 encoding as follows

padding is skipped so the pad character '=' doesn't have to be percent encoded the 62nd and 63rd regular base64 encoding characters ('+' and '/') are replace with ('-' and '_') The changes make the encoding alphabet file and URL safe."

Sorry for the late response, I've been busy. I don't think we need this feature, it will break backwards compatibility without offering any significant benefits. Besides, it's not that hard to change the encoding format, before and after decrypt/encrypt operations.
