PHP - mhash() Functions

The mhash() function can compute a hash.

Syntax

string mhash( int $hash , string $data [, string $key ] )

The mhash() function can apply a hash function specified by hash to the data.

The mhash() function can return the resulting hash (also called digest) or HMAC as a string, or false on error.

Example 1

<?php
   $mes01 = "Water dropping day by day wears the hardest rock away.";

   $alg01 = MHASH_SHA256; // ALGO = 17

   $ctl01 = "6r0pp1n9";

   $hmacD = mhash($alg01, $mes01, $ctl01);
   $hmacH = bin2hex($hmacD);

   echo "ALGO ( " . $alg01 . " )ORIGINAL MESSAGE:" . $mes01 
        . "MHASH RAW-BINARY:" . $hmacD 
        . "MHASH HEXADECIMAL:" . $hmacH;
?> 

Output

ALGO ( 17 )ORIGINAL MESSAGE:Water dropping day by day wears the hardest rock away.MHASH RAW-BINARY:@�KLe.��!��ɧd�u����b��f���2�MHASH HEXADECIMAL:021340804b4c652ea4b121c0d5c9a764dd75f7bbfbfc0262e7dc66899cfa32ef

Example 2

<?php
   $mes02 = "Water dropping day by day wears the hardest rock away.";

   $nbrh = mt_rand(0, 33);

   $alg02 = $nbrh;
   $ctl02 = "6r0pp1n9";

   $hmacD = @mhash($alg02, $mes02, $ctl02);
   $hmacH = bin2hex($hmacD);

   echo "ALGO ( " . $alg02 . " )ORIGINAL MESSAGE:" . $mes02 
        . "MHASH RAW-BINARY:" . $hmacD 
        . "MHASH HEXADECIMAL:" . $hmacH;
?> 

Output
