Hash: SHA1
I thought some other people would be interested in the other hashes
that you can do with mhash that aren't on the php.net docs after the
recent news that SHA-1 might be weaker than previously thought:
http://www.schneier.com/blog/archives/2005/02/sha1_broken.html
The built in constants that the mhash docs have listed are simply
integers that tell mhash what to use. So I found the integers in
mhash's mhash.h:
http://cvs.sourceforge.net/viewcvs.py/mhash/mhash/lib/mhash.h?rev=1.25&view=auto
The following works for alternate hashes in the Win32 PHP 5.0.3
release of libmhash.h. For anyone wanting a step up from SHA-1, SHA256
works.
$hashes = array('CRC32' => 0,
~ 'CRC32B' => 9, ~ 'ADLER32' => 18, ~ 'MD4' => 16, ~ 'MD5' => 1, ~ 'RIPEMD160' => 5, ~ 'SHA1' => 2, ~ 'SHA256' => 17, ~ 'HAVAL128' => 13, ~ 'HAVAL160' => 12, ~ 'HAVAL192' => 11, ~ 'HAVAL224' => 10, ~ 'HAVAL256' => 3, ~ 'TIGER128' => 14, ~ 'TIGER160' => 15, ~ 'TIGER192' => 7, ~ 'GOST' => 8);foreach($hashes as $name => $number) {
~ echo '<br />'; ~ echo $name, ': ', bin2hex(mhash($number, 'this is a test'));} or as PHP constants: $hashes = array('CRC32' => MHASH_CRC32,
~ 'CRC32B' => MHASH_CRC32B, ~ 'ADLER32' => MHASH_ADLER32, ~ 'MD4' => MHASH_MD4, ~ 'MD5' => MHASH_MD5, ~ 'RIPEMD160' => MHASH_RIPEMD160, ~ 'SHA1' => MHASH_SHA1, ~ 'SHA256' => MHASH_SHA256, ~ 'HAVAL128' => MHASH_HAVAL128, ~ 'HAVAL160' => MHASH_HAVAL160, ~ 'HAVAL192' => MHASH_HAVAL192, ~ 'HAVAL224' => MHASH_HAVAL224, ~ 'HAVAL256' => MHASH_HAVAL256, ~ 'TIGER128' => MHASH_TIGER128, ~ 'TIGER160' => MHASH_TIGER160, ~ 'TIGER192' => MHASH_HAVAL192, ~ 'GOST' => MHASH_GOST);foreach($hashes as $name => $number) {
~ echo '<br />'; ~ echo $name, ': ', bin2hex(mhash($number, 'this is a test'));} I suspect if you were able to compile a more recent version of mhash, the following complete list of mhash's hashes would work, including SHA512 and WHIRLPOOL. $hashes = array('CRC32' => 0,
~ 'CRC32B' => 9, ~ 'ADLER32' => 18, ~ 'MD2' => 27, ~ 'MD4' => 16, ~ 'MD5' => 1, ~ 'RIPEMD160' => 5, ~ 'RIPEMD128' => 22, ~ 'RIPEMD256' => 23, ~ 'RIPEMD320' => 24, ~ 'SHA1' => 2, ~ 'SHA224' => 19, ~ 'SHA256' => 17, ~ 'SHA384' => 21, ~ 'SHA512' => 20, ~ 'HAVAL128' => 13, ~ 'HAVAL160' => 12, ~ 'HAVAL192' => 11, ~ 'HAVAL224' => 10, ~ 'HAVAL256' => 3, ~ 'TIGER128' => 14, ~ 'TIGER160' => 15, ~ 'TIGER192' => 7, ~ 'GOST' => 8, ~ 'WHIRLPOOL' => 21, ~ 'SNEFRU128' => 25, ~ 'SNEFRU256' => 26);foreach($hashes as $name => $number) {
~ echo '<br />'; ~ echo $name, ': ', bin2hex(mhash($number, 'this is a test'));} -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.0 (MingW32) Comment: Using GnuPG with Thunderbird - http://enigmail.mozdev.org iD8DBQFCEtHtqLBH+DmBuAIRAhN1AJ9YjaYRNP7d1FVp9zLXNDlBAeWvUQCgutlh 7d+AAPjv1Kh3rWiqld654DE= =dhyN -----END PGP SIGNATURE-----
