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 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.
