How are AES and mcrypt key sizes different?

Therefore they’re using different block sizes which produces entirely different encrypted data as mcrypt uses the number to specify the block size, where OpenSSL used the number to specify the key size (AES only has one block size of 128-bits). So basically AES is Rijndael with a block size of 128-bits and key sizes of 128, 192 and 256 bits.

What kind of encryption is used in mcrypt?

To use with a 32-byte binary key, you can specify aes-256-cbc which is much obvious than MCRYPT_RIJNDAEL_128. Unauthenticated AES-256-CBC encryption library written in Mcrypt with PKCS7 padding.
