Module aes 

Constants

AES_128_KEY_LEN

Length of an AES-128 key in bytes.

AES_192_KEY_LEN

Length of an AES-192 key in bytes.

AES_256_KEY_LEN

Length of an AES-256 key in bytes.

AES_BLOCK_LEN

AES_CBC_IV_LEN

The number of bytes for an AES-CBC initialization vector (IV)

AES_CFB_IV_LEN

The number of bytes for an AES-CFB initialization vector (IV)

AES_CTR_IV_LEN

The number of bytes for an AES-CTR initialization vector (IV)

AES_OFB_IV_LEN

The number of bytes for an AES-OFB initialization vector (IV)

MAX_CFB1_CHUNK_LEN 🔒

Bounds one AES_cfb1_encrypt call so the byte-to-bit conversion cannot overflow, which it would above usize::MAX / 8 = 512 MiB (on a 32-bit target). Mirrors MAXBITCHUNK in AWS-LC’s crypto/decrepit/cfb/cfb.c.

aes_cfb128_decrypt 🔒

aes_cfb128_encrypt 🔒

aes_ctr128_encrypt 🔒

aes_ecb_decrypt 🔒

aes_ecb_encrypt 🔒

aes_ofb128_encrypt 🔒

AES_ofb128_encrypt takes no direction argument: the keystream does not depend on the data, so OFB encryption and decryption are the same operation.

cfb1_cipher 🔒

iv is the feedback register and carries the state across chunks, so splitting the input does not change the result. AES_cfb1_encrypt serves both directions.

cfb1_cipher_in_chunks 🔒

Chunk length is a parameter so tests can reach the multi-chunk path.
