VerifyData()

DSA::VerifyData(const ByteArrayPtr&, const ByteArrayPtr&, const HashAlgorithmName&) method

Verifies that the signature of the specified data is valid.

bool System::Security::Cryptography::DSA::VerifyData(const ByteArrayPtr &data, const ByteArrayPtr &signature, const HashAlgorithmName &hash_algorithm)

Arguments

Parameter	Type	Description
data	const ByteArrayPtr&	Signed data.
signature	const ByteArrayPtr&	Signature data.
hash_algorithm	const HashAlgorithmName&	Hash algorithm. return true if signature is valid, otherwise - false.

DSA::VerifyData(const ByteArrayPtr&, int32_t, int32_t, const ByteArrayPtr&, const HashAlgorithmName&) method

Verifies that the signature of the specified data is valid.

bool System::Security::Cryptography::DSA::VerifyData(const ByteArrayPtr &data, int32_t offset, int32_t count, const ByteArrayPtr &signature, const HashAlgorithmName &hash_algorithm)

Arguments

Parameter	Type	Description
data	const ByteArrayPtr&	Signed data.
offset	int32_t	Offset in data.
count	int32_t	Number of bytes to hash.
signature	const ByteArrayPtr&	Signature data.
hash_algorithm	const HashAlgorithmName&	Hash algorithm. return true if signature is valid, otherwise - false.

DSA::VerifyData(const StreamPtr&, const ByteArrayPtr&, const HashAlgorithmName&) method
