Implementation for php 7.x was added
As you see this implementation is using openssl instead of mcrypt and the result of the encryption/decryption is not compatible with each other.
The mcrypt function will be deprecated feature in PHP 7.1.x

What is AES encryption?
Apr 27, 2016 Encrypt data using AES and 256-bit keys AES stands for Advanced Encryption Standard and is an industry-standard algorithm for encrypting data symmetrically which even the US government has approved for SECRET documents. Generating an AES key. An AES key is a random bitstring of the right length. For a 128-bit AES key you need 16 bytes. For a 256-bit AES key you need 32 bytes. If you need to generate your own AES key for encrypting data, you should use a good random source. The strength of the key depends on the unpredictability of the random. The AES key is nothing more than a specific sized byte array (256-bit for AES 256 or 32 bytes) that is generated by the keytool (see above).
It is a webtool to encrypt and decrypt text using AES encryption algorithm. You can chose 128, 192 or 256-bit long key size for encryption and decryption. The result of the process is downloadable in a text file.

How to use AES encryption?
There are multiple ways of generating an encryption key. Most implementations rely on a random object. All examples mentioned here use a secure cryptographic randomizer.
If you want to encrypt a text put it in the white textarea above, set the key of the encryption then push the Encrypt button.
The result of the encryption will appear in base64 encoded to prevent character encoding problems.
If you want to decrypt a text be sure it is in base64 encoded and is encrypted with AES algorithm!
Put the encrypted text in the white textarea, set the key and push the Decrypt button.

When is helpful to use AES encryption?
When you want to encrypt a confidential text into a decryptable format, for example when you need to send sensitive data in e-mail.
The decryption of the encrypted text it is possible only if you know the right password.

What is AES encryption?
AES (acronym of Advanced Encryption Standard) is a symmetric encryption algorithm.
The algorithm was developed by two Belgian cryptographer Joan Daemen and Vincent Rijmen.
AES was designed to be efficient in both hardware and software, and supports a block length of 128 bits and key lengths of 128, 192, and 256 bits.

AES encryption is used by U.S. for securing sensitive but unclassified material, so we can say it is enough secure.
