Digest::file - Calculate digests of files
This module provide 3 convenience functions to calculate the digest of files. The following functions are provided:
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.
Same as digest_file(), but return the digest in hex form.
Same as digest_file(), but return the digest as a base64 encoded string.
