md5

(PHP 3, PHP 4 )

md5 -- Calculate the md5 hash of a string

Description

string md5 ( string str [, bool raw_output])

Calculates the MD5 hash of str using the RSA Data Security, Inc. MD5 Message-Digest Algorithm, and returns that hash. The hash is a 32-character hexadecimal number. If the optional raw_output is set to TRUE, then the md5 digest is instead returned in raw binary format with a length of 16.

Замечание: The optional raw_output parameter was added in PHP 5.0.0 and defaults to FALSE
