esp_aes_xts_setkey_dec() function

The AES XTS context to which the key should be bound.

The decryption key. This is comprised of the XTS key1 concatenated with the XTS key2.

The size of \p key passed in bits. Valid options are: 256 bits (each of key1 and key2 is a 128-bit key) 512 bits (each of key1 and key2 is a 256-bit key)

XTS-AES buffer encryption/decryption

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

This function prepares an XTS context for encryption and sets the encryption key.

This function releases and clears the specified AES XTS context.
