Message Digest Algorithm 5 (MD5)
MD5 is a hash function, that produce a 128-bit footprint for a value.
MD5 was used a lot for secure hashing and control. Nowadays, it may be useful for hashing and comparing data, though it is not considered secure.
<?php
//Generate a MD5 hash with the history md5() native function
echo hash('md5', 'Le rapide goupil brun sauta par dessus le chien paresseux.');
//Generate a MD5 hash with the history md5() native function
print md5("Some text.")
?>
