KEY_SIZE #

Source 
KEY_SIZE :: 32

Procedures

5

is_hardware_accelerated #

Source 
is_hardware_accelerated :: proc "contextless" () -> bool {…}

is_hardware_accelerated returns true if and only if (⟺) hardware accelerated Deoxys-II is supported.

open #

Source 
@(require_results)
open :: proc(
	ctx:                           ^Context, 
	dst, iv, aad, ciphertext, tag: []u8, 
) -> bool {…}

open authenticates the aad and ciphertext, and decrypts the ciphertext, with the provided Context, iv, and tag, and stores the output in dst, returning true if and only if (⟺) the authentication was successful. If authentication fails, the destination buffer will be zeroed. dst and plaintext MUST alias exactly or not at all.

reset #

Source 
reset :: proc "contextless" (ctx: ^Context) {…}

reset sanitizes the Context. The Context must be re-initialized to be used again.

seal #

Source 
seal :: proc(
	ctx:                          ^Context, 
	dst, tag, iv, aad, plaintext: []u8, 
) {…}

seal encrypts the plaintext and authenticates the aad and ciphertext, with the provided Context and iv, stores the output in dst and tag. dst and plaintext MUST alias exactly or not at all.
