Regarding Ray Paseur's comment, the strings hash to: Note: Before you get some idea like using md5 with password as way to prevent others tampering with message, read pages "Length extension attack" and "Hash-based message authentication code" on wikipedia. Return Value: Returns the converted string. From RFC 1321 - The MD5 Message-Digest Algorithm: "The MD5 message-digest algorithm takes as input a message of arbitrary length and produces as output a 128-bit "fingerprint" or "message digest" of the input. for details and best practices. In Brute-Force we specify a Charset and a password length range. md5是MD5加密的函数 This is quite a lot faster. 개요 md5()는 문자열에서 md5 해시값을 생성하는 함수입니다.
