Facebook Signature incorrect

Question

Hi there,

I'm Verifying the signature just like this: http://wiki.developers.facebook.com/ind … _Signature

but there's something wrong:

when creating md5 from concatenated string (cookies: expires, session_key, ss, user) plus application secret ... i'm getting different results as it follows:

Example: cookie with signature value: 093dc0c322c04cd35bc2c1d83137219d md5(cookies plus secret) : 93dc0c322c04cd35bc2c1d83137219d

The only difference here is the first digit.

I was doing this signature verification without any problems until now.

I was using the API key and Application secret of an application that i've created on facebook account. Now, i've created a new application on my enterprise facebook page and i'm using the API key and application secret of this new application. Now, it's not working

Does anyone knows what happened?

Thanks

You need the leading zero.
