MD5 Encryption :
$str = "Hello";
echo md5($str);
if (md5($str) == '8b1a9953c4611296a827abf8c47804d7')
{
echo "
Hello world!";
exit;
}
The output of the above code would be :
8b1a9953c4611296a827abf8c47804d7
Hello world!
Crypt Encryption :
$password = crypt('mypassword'); // let the salt be automatically generated
/* You should pass the entire results of crypt() as the salt for comparing a
password, to avoid problems when different hashing algorithms are used. (As
it says above, standard DES-based password hashing uses a 2-character salt,
but MD5-based hashing uses 12.) */
if (crypt($user_input, $password) == $password) {
echo "Password verified!";
}
