esp_aes_setkey() function

AES context to be initialized

encryption key

must be 128, 192 or 256

This function releases and clears the specified AES context.

This function initializes the specified AES context. It must be the first API called before using the context.

AES-ECB block encryption/decryption

AES-CTR buffer encryption/decryption Warning: You have to keep the maximum use of your counter in mind! Note: Due to the nature of CTR you should use the same key schedule for both encryption and decryption. So a context initialized with esp_aes_setkey_enc() for both AES_ENCRYPT and AES_DECRYPT.

AES-CBC buffer encryption/decryption Length should be a multiple of the block size (16 bytes)

AES-CFB128 buffer encryption/decryption. Note: Due to the nature of CFB you should use the same key schedule for both encryption and decryption. So a context initialized with esp_aes_setkey_enc() for both AES_ENCRYPT and AES_DECRYPT.

This function performs an AES-OFB (Output Feedback Mode) encryption or decryption operation.

Internal AES block encryption function (Only exposed to allow overriding it, see AES_ENCRYPT_ALT)

Internal AES block decryption function (Only exposed to allow overriding it, see AES_DECRYPT_ALT)

AES-CFB8 buffer encryption/decryption. Note: Due to the nature of CFB you should use the same key schedule for both encryption and decryption. So a context initialized with esp_aes_setkey_enc() for both AES_ENCRYPT and AES_DECRYPT.
