HMAC Algorithm #7
Description
In the HMAC algorithm code, there is a line:
secret = v + 1
When I enable debug and print the value of secret and string_to_sign variables, secret is really string_to_sign and string_to_sign is null. It seems that v is a pointer to the last variable in the conf for that directive. However, when I change secret = v -1, the data for secret ends up being the value of secret + the value of string_to_sign concated together.
With secret = v-1
set $secret 'yzY3mIMZfyO03';
set $string_to_sign 'ec_country_allow=US';
set_hmac_sha1 $tok $secret $string_to_sign;
from log:
secret=yzY3mIMZfyO03ec_country_allow=US, string_to_sign=ec_country_allow=US
With secret = v+1
secret=ec_country_allow=US, string_to_sign=(null)
Any ideas? Thank you
