MessageDigestSpi.EngineDigest Method

  • Reference

Definition

Namespace:
Java.Security
Assembly:
Mono.Android.dll

Overloads

EngineDigest()

Completes the hash computation by performing final operations such as padding.
EngineDigest(Byte[], Int32, Int32)

Completes the hash computation by performing final operations such as padding.

EngineDigest()

Completes the hash computation by performing final operations such as padding.

[Android.Runtime.Register("engineDigest", "()[B", "GetEngineDigestHandler")]
protected abstract byte[]? EngineDigest ();
[<Android.Runtime.Register("engineDigest", "()[B", "GetEngineDigestHandler")>]
abstract member EngineDigest : unit -> byte[]

Returns

Byte[]

the array of bytes for the resulting hash value.

Attributes
RegisterAttribute

Remarks

Completes the hash computation by performing final operations such as padding. Once engineDigest has been called, the engine should be reset (see #engineReset() engineReset). Resetting is the responsibility of the engine implementor.

EngineDigest(Byte[], Int32, Int32)

Completes the hash computation by performing final operations such as padding.

[Android.Runtime.Register("engineDigest", "([BII)I", "GetEngineDigest_arrayBIIHandler")]
protected virtual int EngineDigest (byte[]? buf, int offset, int len);
[<Android.Runtime.Register("engineDigest", "([BII)I", "GetEngineDigest_arrayBIIHandler")>]
abstract member EngineDigest : byte[] * int * int -> int
override this.EngineDigest : byte[] * int * int -> int

Parameters

buf
Byte[]

the output buffer in which to store the digest

offset
Int32

offset to start from in the output buffer

len
Int32

number of bytes within buf allotted for the digest. Both this default implementation and the SUN provider do not return partial digests. The presence of this parameter is solely for consistency in our API's. If the value of this parameter is less than the actual digest length, the method will throw a DigestException. This parameter is ignored if its value is greater than or equal to the actual digest length.

Returns

Int32

the length of the digest stored in the output buffer.

Attributes
RegisterAttribute

Exceptions

DigestException

if an error occures.

IllegalArgumentException

if offset or len are not valid in respect to buf.

Remarks

Completes the hash computation by performing final operations such as padding. Once engineDigest has been called, the engine should be reset (see #engineReset() engineReset). Resetting is the responsibility of the engine implementor.

This method should be abstract, but we leave it concrete for binary compatibility. Knowledgeable providers should override this method.
