iphone - Can iOS really support AES 256? -

-

i have read header of commoncryptor.h, , can find kccalgorithmaes128

but there few answer in stating can, e.g.

aes encryption nsstring on iphone

anyone can answer?

you can use openssl on iphone, , support aes 256.

that being said, kccalgorithmaes128 means block length of 128, not key length. according this example code (found in this answer) need use kcckeysizeaes256 keylength parameter support 256 bit keys.
