oauth_problem=signature_invalid

Question

I'm using pecl oauth in php, it workds fine in plain php using localhost, and I was able to get the request token. But when I use it on a framework, it throws exception and gives me oauth_problem=signature_invalid.

this framework is being used on a virtual host. Any idea?

Answer 1

Two of your three paste bins aren't working for me, but I'm also creating an OAuth provider myself and I ran into a problem with my keys. How are you storing them in the database?

In my case, I was saving the SHA1 keys into BINARY(20) columns by calling the MYSQL function UNHEX() when I inserted them and then calling HEX() when I pulled them out[1]. The problem was that HEX and UNHEX return uppercase values, and when I was generating the SHA1 keys using the sha1() function they were lowercase[2]. Make sure they are the same case, because it will affect the signature.
