Description

Encoding tag implementing Base64URL, as per http://www.ietf.org/rfc/rfc4648.txt. (Essentially the same as the Base64 encoding scheme but the '=' padding character is omitted and the '+' & '/' characters are exchanged for the URL-safe '-' & '_'.)

Sample Usage

Encode_Base64URL( encrypt_blowfish2('Hello world James Harvard 12345',-seed='secret') );
// returns "SW9h_SZVfV0x1T9BSuLPEBdvlZWXZOe9b1LeTYp-9A" which is safe for use in URLs

// For comparison:
Encode_Base64( encrypt_blowfish2('Hello world James Harvard 12345',-seed='secret') );
// returns "SW9h/SZVfV0x1T9BSuLPEBdvlZWXZOe9b1LeTYp+9A=="
