| 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:
-
src pointer to 128-bit plaintext in dst pointer 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 Use of the preset key is no longer valid after this call.

| 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:
-
key pointer to 128-bit AES key
