    Types

    Context ¶
    Source

    Context :: struct {
	_subkeys:        [17][16]u8,
	_impl:           aes.Implementation,
	_is_initialized: bool,
}
     

    Context is a keyed Deoxys-II-256 instance.

    Constants

    IV_SIZE ¶
    Source

    IV_SIZE: int : 15
     

    IV_SIZE iss the Deoxys-II-256 IV size in bytes.

    KEY_SIZE ¶
    Source

    KEY_SIZE: int : 32
     

    KEY_SIZE is the Deoxys-II-256 key size in bytes.

    TAG_SIZE ¶
    Source

    TAG_SIZE: int : 16
     

    TAG_SIZE is the Deoxys-II-256 tag size in bytes.

    Procedures

    init ¶
    Source

    init :: proc(ctx: ^Context, key: []u8, impl: aes.Implementation = aes.DEFAULT_IMPLEMENTATION) {…}
     

    init initializes a Context with the provided key.

    is_hardware_accelerated ¶
    Source

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

    is_hardware_accelerated returns true iff hardware accelerated Deoxys-II is supported.

    open ¶
    Source

    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 iff 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.
