Digest::file - Calculate digests of files

(@ARGV) { print digest_file_hex($_, “MD5”), “ $_\n”; }

This module provide 3 convenience functions to calculate the digest of files. The following functions are provided:

digest_file( $file, $algorithm, [$arg,…] )

This function will calculate and return the binary digest of the bytes of the given file. The function will croak if it fails to open or read the file. The $algorithm is a string like MD2, MD5, SHA-1, SHA-512. Additional arguments are passed to the constructor for the implementation of the given algorithm.

digest_file_hex( $file, $algorithm, [$arg,…] )

Same as digest_file(), but return the digest in hex form.

digest_file_base64( $file, $algorithm, [$arg,…] )

Same as digest_file(), but return the digest as a base64 encoded string.
