Rijndael 128 frente a aes 256

Use different random data for the initialisation vector each time encryption is made with the same key. mcrypt_create_iv() is one choice for random data. Template:Infobox block cipher. The Advanced Encryption Standard (AES) is a symmetric-key encryption standard adopted by the U.S. government. The standard comprises three block ciphers, AES-128, AES-192 and AES-256 The default encryption algorithm is: aes128-sha1 aes256-sha1 aes128-sha256 aes256-sha256 aes128gcm aes256gcm chacha20poly1305. With null encryption, IPsec traffic can offload NPU/CP. FortiOS supports I read recently that Fedora only offers AES 128 LUKS encryption.

I notice that the question is captioned AES RIJNDAEL 256 but the first line of PHP code says this: $cipher = mcrypt_module_open(MCRYPT_RIJNDAEL_128, '', MCRYPT_MODE_CBC You encrypt the entire thing with AES-256 using a random IV that you prepend to the message.

So the block size is always 128. I can't point you to any official documentation because (so far as I'm aware) AES- has always been an unofficial shorthand. Rijndael was the only AES candidate which defined a different number of rounds for their 128, 192, and 256-bit versions (10, 12, and 14, respectively). The others had a fixed number of rounds (32 for Serpent, 16 for Twofish, etc.) regardless of the key size.
