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.
