EngineGenerateSecret()
Generates the shared secret and returns it in a new buffer.
[Android.Runtime.Register("engineGenerateSecret", "()[B", "GetEngineGenerateSecretHandler")]
protected abstract byte[]? EngineGenerateSecret ();[<Android.Runtime.Register("engineGenerateSecret", "()[B", "GetEngineGenerateSecretHandler")>]
abstract member EngineGenerateSecret : unit -> byte[]Returns
the new buffer with the shared secret
- Attributes
Exceptions
if this key agreement is not complete.
Remarks
Generates the shared secret and returns it in a new buffer.
This method resets this KeyAgreementSpi object, so that it can be reused for further key agreements. Unless this key agreement is reinitialized with one of the engineInit methods, the same private information and algorithm parameters will be used for subsequent key agreements.

abstract member EngineGenerateSecret : string -> Javax.Crypto.ISecretKeyParameters
- algorithm
- String
the requested secret key algorithm
Returns
the shared secret key
- Attributes
Exceptions
if this key agreement is not complete.
if the specified algorithm for the secret key does not exists.
if a SecretKey with the specified algorithm cannot be
created using the generated shared secret.
Remarks
Creates the shared secret and returns it as a secret key object of the requested algorithm type.

Applies to
EngineGenerateSecret(Byte[], Int32)
Generates the shared secret, and places it into the buffer
sharedSecret, beginning at offset inclusive.
[Android.Runtime.Register("engineGenerateSecret", "([BI)I", "GetEngineGenerateSecret_arrayBIHandler")]
protected abstract int EngineGenerateSecret (byte[]? sharedSecret, int offset);[<Android.Runtime.Register("engineGenerateSecret", "([BI)I", "GetEngineGenerateSecret_arrayBIHandler")>]
abstract member EngineGenerateSecret : byte[] * int -> intParameters
- sharedSecret
- Byte[]
the buffer for the shared secret
- offset
- Int32
the offset in sharedSecret where the
shared secret will be stored
Returns
the number of bytes placed into sharedSecret
- Attributes
Exceptions
if this key agreement is not complete.
if the specified buffer is too small for the shared secret.
Remarks
Generates the shared secret, and places it into the buffer sharedSecret, beginning at offset inclusive.
If the sharedSecret buffer is too small to hold the result, a ShortBufferException is thrown. In this case, this call should be repeated with a larger output buffer.
