Function Documentation

void aes_decrypt ( void *  ctx,
const u8 crypt,
u8 plain 
)

aes_decrypt - Decrypt one AES block : Context pointer from aes_encrypt_init() : Encrypted data (16 bytes) : Buffer for the decrypted data (16 bytes)

Definition at line 141 of file aes-internal-dec.c.

void aes_decrypt_deinit ( void *  ctx  ) 

aes_decrypt_deinit - Deinitialize AES decryption : Context pointer from aes_encrypt_init()

Definition at line 147 of file aes-internal-dec.c.

void* aes_decrypt_init ( const u8 key,
size_t  len 
)

aes_decrypt_init - Initialize AES for decryption : Decryption key : Key length in bytes (usually 16, i.e., 128 bits) Returns: Pointer to context data or NULL on failure

Definition at line 62 of file aes-internal-dec.c.

static void rijndaelDecrypt ( const u32  rk[],
const u8  ct[16],
u8  pt[16] 
) [static]

Definition at line 74 of file aes-internal-dec.c.

void rijndaelKeySetupDec ( u32  rk[],
const u8  cipherKey[] 
)

Expand the cipher key into the decryption key schedule.

Returns:
the number of rounds for the given cipher key size.
