sha512

[marquis]

how do u use sha512 i can get sha1 to work but not 512

[MrAdam]

well i think you'd need to use it with the "mhash()" function, an example of it using md5:mhash(MHASH_MD5, $str);i'm not sure if "sha512" is valid or not.. the mhash function doesn't come as a standard with PHP i believe, you have download it.

Sha512 isn't supported by PHP (yet).. just use Md5 (only the easy way comparing with MrAdam's code ):

md5 ( 'mypassword/string' );

SHA-512 might be supported, depending on your version of PHP. PHP 5.2.0, for example, does support SHA-512. Use this code to determine which hashing algorithms your system supports:

<?phpprint_r(hash_algos());?>

On the server that I am on, I see this result:

Array(	[0] => md4	[1] => md5	[2] => sha1	[3] => sha256	[4] => sha384	[5] => sha512	[6] => ripemd128	[7] => ripemd160	[8] => whirlpool	[9] => tiger128,3	[10] => tiger160,3	[11] => tiger192,3	[12] => tiger128,4	[13] => tiger160,4	[14] => tiger192,4	[15] => snefru	[16] => gost	[17] => adler32	[18] => crc32	[19] => crc32b	[20] => haval128,3	[21] => haval160,3	[22] => haval192,3	[23] => haval224,3	[24] => haval256,3	[25] => haval128,4	[26] => haval160,4	[27] => haval192,4	[28] => haval224,4	[29] => haval256,4	[30] => haval128,5	[31] => haval160,5	[32] => haval192,5	[33] => haval224,5	[34] => haval256,5)

That means that I can use any of those algorithms with the hash function:

hash("sha512", $str);hash("whirlpool", $str);hash("haval256,4", $str);
