Md5 hash: Encryption of a string |
md5 returns the hash of a string. This is used to encrypt strings and particularly encrypting the passwords of the user. This function returns the encrypted string by using RSA Data Security Inc.
Let us try to learn how to use this function.
$str="Hello";
echo md5($str);
The output of the above code will be
8b1a9953c4611296a827abf8c47804d7
md5 encryption is useful to store passwords and other sensitive data. md5 encryption is one way only, there is no standard method to generate the source or the original string from the hash of the string. So passwords can't be retrieved and it can only be reset.
Here is a script to display the md5 output for a given string.
Maximum 8 char length allowed
