encrypt->decode producing blank output

[SOLVED]
Thanks noctrum. I just figured it out. I had my fields set as varchar with a length of 35. I had forgotten that the encryption function can make the encrypted fields up to 3 or more times the length after encryption. I changed my fields to TEXT format and now it's working fine,

Just out of interest. Would it be a good idea to MD5 the result to end up with consistent sized results?

cheers,
