Checksum on a File?

[JRyanCon]

I am trying to figure out how to run a md5 on a file.

I have seen this done against a string. For instance:

md5pure::md5 "hello world"


But I would like to be able to run it against a file. Any suggestions you might be able to point me at?

Thank

md5::hmac $options, but this is not a checksum and I'm not sure it fits the bill. Try the man pages for crc32 or crc16,
or the active state docs here:
