digest-file

Arguments: md-name filespec return

You may need to evaluate (require :digest) to load the digest code before calling this function.

Using digest-init, digest-update, and digest-final, compute the hash on the contents of the file given by filespec.

name can be one of the symbols md2, md4, md5, sha1, sha224, sha256, sha384, sha512, and rmd160, specifying the type of hashing.

This function returns the value of digest-final on the implicitly created context. The return argument is passed to digest-final (where the various possible values are discussed). Note the warning about integer returns perhaps losing leading 0's.

See MD5, SHA*, HMAC, RC4, and other message digest support in miscellaneous.htm.
