Base64url Encoding

See more Encryption Examples

Base64url encoding is identical to base64 encoding except it uses non-reserved URL characters (e.g. '–' is used instead of '+', and '_' is used instead of '/') and it omits the padding characters. CkPython

import chilkat

success = False

# This example requires the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

pkey = chilkat.CkPrivateKey()
rsa = chilkat.CkRsa()
rsa.GenKey(1024,pkey)
rsa.UsePrivateKey(pkey)

strData = "This is the string to be signed."

# Get the signature in base64url
rsa.put_EncodingMode("base64url")
strSig = rsa.signStringENC(strData,"sha256")

print(strSig)
