NAME
Digest::file - Calculate digests of filesSYNOPSIS
# Poor mans "md5sum" command
use Digest::file qw(digest_file_hex);
for (@ARGV) {
print digest_file_hex($_, "MD5"), " $_\n";
}
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.
is a string like ``MD2'', ``MD5'', ``SHA-1'', ``SHA-512''. Additional arguments are passed to the constructor for the implementation of the given algorithm.The $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. - 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.
