It depends. CRC is a pretty weak algorithm that is merely intented to catch transmission errors (but is fairly lightweight in its calculation). Cryptographic hashes (MD5, SHA1, MD160) are strong (but slow) algorithms to improve your degree of trust that nobody manipulated the files protected by them. Of course, as both are transfered within the same file, the value of the cryptographic hash is somewhat questionable. -- cheers, J"org .-.-. --... ...-- -.. .
