NAME
Digest::file - Calculate digests of files
SYNOPSIS
# Poor mans "md5sum" command
use Digest::file qw(digest_file_hex);
for (@ARGV) {
print digest_file_hex($_, "MD5"), " $_
";
}
DESCRIPTION
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.
