Hello,

not familiar with python functions, have you tried with Kamailio transformation?

https://www.kamailio.org/wiki/cookbooks/5.5.x/transformations#sdecodebase64url

Maybe you have to specify in Python that it is ASCII, I remember I had to do decoding when porting kamcli to work with Python3 -- had to change from using directly the variables received as parameter to a decoded value, something like:

prefix = tprefix.encode("ascii", "ignore").decode()

Also, if you can, share the identity header here to test with and see if can be reproduced.

Cheers,
Daniel

I am unable to base64url decode the json payload in identity header generated by secsipid.

 

(Using python for test)

decoded_payload = url64.decode(‘payload’)

UnicodeDecodeError: 'utf-8' codec can't decode byte 0xc2 in position 27: invalid continuation byte

 

Header decodes fine this way but not payload.

 

Is this an issue with the payload encoding?
