Size of SHA1 or MD5 hash hex-encoded?

Hello. I'm just trying to mess around with the MHASH-library functions to create MD5 and SHA1 hashes. Is there a limit to how large the output from mhash(MHASH_MD5, $input) or mhash(MHASH_SHA1, $input) will be? I'd like to store some MD5 (or SHA1) hashes in a database (after converting them from binary to hex) and I need to know how large the hashes can be. I've tried looking at the PHP documentation on the 'net but have not been able to find this out by myself. Can anyone help? -- Eivind Olsen eivind@aminor.no
