Aes 128 Random Key
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. I want to create random AES Encryption key (128 bit) in ios. I have searched in SO but I cannot find a good answer. Please give me some advice. Thanks in advance. UPDATE: I have used BBAES lib. I used the below code to generate the encryption key but when I convert from NSData to NSString, it shows NULL. AES was chosen as a subset of the family of block ciphers known as Rijndael. That family includes no less than 15 variants, for three possible block sizes (128, 192 and 256 bits) and five possible key sizes (128, 160, 192, 224 and 256 bits). IKEv2 Cipher Suites¶. IKEv2 Cipher Suites. The keywords listed below can be used with the ike and esp directives in ipsec.conf or the proposals settings in swanctl.conf to define cipher suites. IANA provides a complete list of algorithm identifiers registered for IKEv2. Jun 14, 2016 An AES-128 expects a key of 128 bit, 16 byte. To generate such a key, use OpenSSL as: openssl rand 16 myaes.key AES-256 expects a key of 256 bit, 32 byte. To generate such a key, use: openssl rand 32 myaes.key – ingenue Oct 12 '17 at 11:57.

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?
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?
Aes 128 Random Key Generator
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.

How secure is AES encryption algorithm?
Random Aes 128 Key
AES encryption is used by U.S. for securing sensitive but unclassified material, so we can say it is enough secure.
