CipherSpi.EngineUpdateAAD Method

  • Reference

Definition

Namespace:
Javax.Crypto
Assembly:
Mono.Android.dll

Overloads

EngineUpdateAAD(ByteBuffer)

Continues a multi-part update of the Additional Authentication Data (AAD).
EngineUpdateAAD(Byte[], Int32, Int32)

Continues a multi-part update of the Additional Authentication Data (AAD), using a subset of the provided buffer.

EngineUpdateAAD(ByteBuffer)

Continues a multi-part update of the Additional Authentication Data (AAD).

[Android.Runtime.Register("engineUpdateAAD", "(Ljava/nio/ByteBuffer;)V", "GetEngineUpdateAAD_Ljava_nio_ByteBuffer_Handler")]
protected virtual void EngineUpdateAAD (Java.Nio.ByteBuffer? src);
[<Android.Runtime.Register("engineUpdateAAD", "(Ljava/nio/ByteBuffer;)V", "GetEngineUpdateAAD_Ljava_nio_ByteBuffer_Handler")>]
abstract member EngineUpdateAAD : Java.Nio.ByteBuffer -> unit
override this.EngineUpdateAAD : Java.Nio.ByteBuffer -> unit

Parameters

src
ByteBuffer

the buffer containing the AAD

Attributes
RegisterAttribute

Remarks

Continues a multi-part update of the Additional Authentication Data (AAD).

Calls to this method provide AAD to the cipher when operating in modes such as AEAD (GCM/CCM). If this cipher is operating in either GCM or CCM mode, all AAD must be supplied before beginning operations on the ciphertext (via the update and doFinal methods).

All src.remaining() bytes starting at src.position() are processed. Upon return, the input buffer's position will be equal to its limit; its limit will not have changed.

EngineUpdateAAD(Byte[], Int32, Int32)

Continues a multi-part update of the Additional Authentication Data (AAD), using a subset of the provided buffer.

[Android.Runtime.Register("engineUpdateAAD", "([BII)V", "GetEngineUpdateAAD_arrayBIIHandler")]
protected virtual void EngineUpdateAAD (byte[]? src, int offset, int len);
[<Android.Runtime.Register("engineUpdateAAD", "([BII)V", "GetEngineUpdateAAD_arrayBIIHandler")>]
abstract member EngineUpdateAAD : byte[] * int * int -> unit
override this.EngineUpdateAAD : byte[] * int * int -> unit

Parameters

src
Byte[]

the buffer containing the AAD

offset
Int32

the offset in src where the AAD input starts

len
Int32

the number of AAD bytes

Attributes
RegisterAttribute

Exceptions

IllegalStateException

if this cipher instance is not initialized for encryption or decryption.

IllegalArgumentException

if input is null, or if inputOffset and inputLen do not specify a valid chunk in the input buffer.

UnsupportedOperationException

if the cipher does not support AEAD
