Detailed Description

This class provides high-level interface to sign and verify data using Virgil Security keys.

This module can sign / verify data that is fed to the signer sequentially.

Constructor & Destructor Documentation

virgil::crypto::VirgilSeqSigner::VirgilSeqSigner ( foundation::VirgilHash::Algorithm  hashAlgorithm = foundation::VirgilHash::Algorithm::SHA384 )

explicit

Create signer with predefined hash function.

Note

Specified hash function algorithm is used only during signing.

Member Function Documentation

VirgilByteArray virgil::crypto::VirgilSeqSigner::sign	(	const VirgilByteArray &	privateKey,
		const VirgilByteArray &	privateKeyPassword = VirgilByteArray()
	)

Sign data that was collected by update() function.

Returns

Virgil Security sign.

void virgil::crypto::VirgilSeqSigner::startSigning

(

)

Start new data signing.

void virgil::crypto::VirgilSeqSigner::startVerifying

(

const VirgilByteArray &

signature

)

Start new data verifying.

Parameters

signature

-

void virgil::crypto::VirgilSeqSigner::update

(

const VirgilByteArray &

data

)

Append new data chunk to be signed or verified.

Parameters

data	- next data chunk.

bool virgil::crypto::VirgilSeqSigner::verify

(

const VirgilByteArray &

publicKey

)

Verify sign and data that was collected by update() function to be conformed to the given public key.

Returns

true if sign is valid and data was not malformed.
