Digest::file - Calculate digests of files
# Poor mans "md5sum" command use Digest::file qw(digest_file_hex); for (@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 dig- est 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 con- structor 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.
