Creating Custom HIPS Signature using MD5 Hash

I'm trying to create a custom HIPS signature to block the fingerprint of 7fce8905e30590e8849ds50604870a6f; however, when entering that MD5 hash into the Fingerprint area of the custom signature, I am receiving the !! and cannot save the policy.

I have other hashes saved from previous policies and the length of the numbers match up.  I manually entered in the hash, and even lower cased the letters to see if that worked.  Nope.

Can someone please help me with this one?

Re: Creating Custom HIPS Signature using MD5 Hash

The letter "s" is not a valid hexadecimal value.
