KRL: Signing Queries with HMAC_SHA1

I made a set of tests for mathematical functions: hmac_ * KRL. I am comparing KRL results with Python results. KRL gives me different results.

code: https://gist.github.com/980788 results: http://ktest.heroku.com/a421x68

How can I get valid signatures from KRL? I assume the Python results are correct.

UPDATE: it works great if you don't need newlines in the message. How to sign a line containing newline characters?
