Cypher for .net

PGPBase..::..VerifyData Method

Verifies that a digital signature is valid by calculating the hash value of the data in a portion of a byte array using the specified hash algorithm and padding, and comparing it to the provided signature.

Assembly:  Walter.Cypher (in Walter.Cypher.dll)

Syntax


public bool VerifyData(
	byte[] data,
	int offset,
	int count,
	byte[] signature,
	HashAlgorithmName hashAlgorithm,
	RSASignaturePadding padding
)

Parameters

data
Type: array<Byte>[]()[][]
The signed data.
offset
Type: Int32
The starting index at which to compute the hash.
count
Type: Int32
The number of bytes to hash.
signature
Type: array<Byte>[]()[][]
The signature data to be verified.
hashAlgorithm
Type: HashAlgorithmName
The hash algorithm used to create the hash value of the data.
padding
Type: RSASignaturePadding
The padding mode.

Return Value

true if the signature is valid; otherwise, false.
