Function Documentation

void arm_aes_encrypt ( const uint8_t  src[__static 16],
uint8_t  dst[__static 16] 
)

This function performs dst=E[preset key,src] (Simple ECB block).

This function performs a single-block AES encryption, using the preset key. It is called between arm_aes_start() and arm_aes_finish(). Note that src and dst pointers may be equal.

Parameters:
srcpointer to 128-bit plaintext in
dstpointer for 128-bit ciphertext out
void arm_aes_finish ( void   )

Finish AES operations.

This function is called to terminate a series of AES operations. It may be a no-op, or it may disable AES hardware. Use of the preset key is no longer valid after this call.

Definition at line 76 of file aes_mbedtls_adapter.c.

void arm_aes_start ( const uint8_t  key[__static 16] )

Set the AES key.

This function sets the 128-bit AES key that will be used for future calls to arm_aes_encrypt(). The key must be copied by the function.

Parameters:
keypointer to 128-bit AES key
