Methods

BlockUpdate(byte[], int, int)

Update the signer with a block of bytes.

public virtual void BlockUpdate(byte[] input, int inOff, int inLen)

Parameters

input byte[]

the byte array containing the data.

inOff int

the offset into the byte array where the data starts.

inLen int

the length of the data.

BlockUpdate(ReadOnlySpan<byte>)

Update the signer with a span of bytes.

public virtual void BlockUpdate(ReadOnlySpan<byte> input)

Parameters

input ReadOnlySpan<byte>

the span containing the data.

GenerateSignature()

Generate a signature for the message we've been loaded with using the key we were initialised with.

public virtual byte[] GenerateSignature()

Returns

byte[]

A byte array containing the signature for the message.

GetMaxSignatureSize()

public virtual int GetMaxSignatureSize()

Returns

int

Init(bool, ICipherParameters)

Initialise the signer for signing or verification.

public virtual void Init(bool forSigning, ICipherParameters parameters)

Parameters

forSigning bool

true if for signing, false otherwise.

parameters ICipherParameters

necessary parameters.

Reset()

Reset the signer back to its initial state.

public virtual void Reset()

Update(byte)

Update the signer with a single byte.

public virtual void Update(byte b)

Parameters

b byte

VerifySignature(byte[])

Return true if the internal state represents the signature described in the passed in array.

public virtual bool VerifySignature(byte[] signature)

Parameters

signature byte[]

an array containing the candidate signature to verify.

Returns

bool

true if the internal state represents the signature described in the passed in array.
