RSACryptoServiceProvider.VerifyData Method

Verifies the specified signature data by comparing it to the signature computed for the specified data.

Namespace: System.Security.Cryptography
Assembly: mscorlib (in mscorlib.dll)

public bool VerifyData (
	byte[] buffer,
	Object halg,
	byte[] signature
)
public boolean VerifyData (
	byte[] buffer, 
	Object halg, 
	byte[] signature
)
public function VerifyData (
	buffer : byte[], 
	halg : Object, 
	signature : byte[]
) : boolean

Parameters

buffer

The data that was signed.

halg

The name of the hash algorithm used to create the hash value of the data.

signature

The signature data to be verified.

Return Value

true if the signature verifies as valid; otherwise, false.

Exception typeCondition

ArgumentNullException

The halg parameter is a null reference (Nothing in Visual Basic).

ArgumentException

The halg parameter is not a valid type.

This method verifies the RSA digital signature produced by SignData.

The halg parameter can accept a String, a HashAlgorithm, or a Type.
