Mcrypt is deprecated, what is the alternative? As deprecated earlier; use mcrypt_encrypt and mcrypt_decrypt. Copy of php with mcrypt to decrypt the old data. As of PHP 7.1, the php-mcrypt was deprecated. And as of PHP 7.2 it was completely removed. This is a problem, since a number of server software titles still depend upon this encryption tool.

Note that the IV must be the same for mcrypt_encrypt and mcrypt_decrypt, otherwise you will have corrupted data after decryption. Pass it to php, and do it again. Mcrypt can be used to encrypt and decrypt using the above mentioned ciphers. If you linked against libmcrypt-2.2.x, the four important mcrypt commands. I could En/Decrypt within VB and PHP just fine But when I tried to encrypt one in VB and decrypt in PHP.
I'm looking for a simple yet cryptographically strong PHP implementation of AES using Mcrypt.
Hoping to boil it down to a simple pair of functions, $garble = encrypt($key, $payload) and $payload = decrypt($key, $garble).

Php Encryption Password
I'm recently learning about this subject, and am posting this answer as a community wiki to share my knowledge, standing to be corrected.
It's my understanding that AES can be achieved using Mcrypt with the following constants as options:
During encryption, a randomized non-secret initialization vector (IV) should be used to randomize each encryption (so the same encryption never yields the same garble). This IV should be attached to the encryption result in order to be used later, during decryption.
Results should be Base 64 encoded for simple compatibility.
Implementation:
Output looks like this:
Add function to clean control characters (�).

Class Mycrypt
Try using this class. Here. All you need to pass is key and string.

This code is rather inefficient, I'm not surprised it doesn't give intended results.
Tested and it appears to work fine for me.
Either way I feel I should warn you that this is a really insecure form of encryption, most passwords use the same sets of characters and a fairly small range of lengths, which makes this system very vulnerable to people being able to work out with a fairly good level of accuracy the password.

Here's another method:

trantetranteI used jlogsdon enc_encrypt and enc_decrypt in prestashop 1.4.4.1 to wrap encrypt and decrypt methods from Rijndael class, witch are using mcrypt. I didn'e check if enc_encrypt and enc_decrypt give exacly the same resulst as mcrypt_encrypt and mcrypt_decrypt, but they seem to work in prestashop 1.4.4.1. Thanks a lot.
Php Encrypt Decrypt Without Mcrypt
The question is old but, as PHP 7 don't have mcrypt, I had the same problem. The best solution I found is using OpenSSL. It is built into PHP and you don't need any external library.
