I observed a similar behavior, but it was the result of my cutting and pasting the
identity header from sngrep, which looks to have dropped a few bytes on the line break.
Any chance that’s what you’re doing, too?

Subject: Re: [SR-Users] SECSIPID Identity Decode
Here is an example, payload taken from Identity header.
Identity was added with secsipid_add_identity
Payload test:
$var(test) =
"eyJhdHRlc3QiOiJBIiwiZGVzdCI6eyJ0biI6I5ODkyODkyMjgwIl19LCJpYXQiOjE2MjUxMDk2MzQsIm9yaWciOnsidG4iOiI5ODk0MDA0MjMwIn0sIm9yaWdpZCI6IjNmYmE4NTg0LTRkNzMtNGU2NC04NDc5LTQ5MjU2ZGIyMWFhYSJ9";
xlogl("L_WARN", "$(var(test){s.decode.base64t})\n");
Result is:
{"attest":"A","dest":{"tn":#���#��##�#002%���&�#027B#�#023c#S#023#003�#023sB�&�&�r#��'F�#�#���C#003#003C#3#002'��&�&�v�B#�Vc�s#006f"�&6#026#022�CVCB�#023c3#022�3#0066#�#026#6#026S�r'

Subject: Re: [SR-Users] SECSIPID Identity Decode
That’s the same way I am doing it, I was just trying to do a verification that the
identity header/payload was correct before activating new changes.
I will do further testing and share results. Just found it odd that the header would
decode but payload wouldn’t.

I DO IT WITH:
# Break JWT
$var(jwt1) = $(hdr(Identity){s.select,0,.}{s.decode.base64t});
$var(jwt2) = $(hdr(Identity){s.select,1,.}{s.decode.base64t});

Hello,
not familiar with python functions, have you tried with Kamailio transformation?
https://www.kamailio.org/wiki/cookbooks/5.5.x/transformations#sdecodebase64…
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?
