AsymmetricSignatureDeformatter.VerifySignature Method (HashAlgorithm, Byte[])

Verifies the signature from the specified hash value.

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

abstract VerifySignature : 
        hash:HashAlgorithm * 
        rgbSignature:byte[] -> bool  
override VerifySignature : 
        hash:HashAlgorithm * 
        rgbSignature:byte[] -> bool


Type: System.Security.Cryptography.HashAlgorithm

The hash algorithm to use to verify the signature.

Type: System.Byte[]

The signature to be verified.

Return Value

Type: System.Boolean
true if the signature is valid for the hash; otherwise, false.


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

This method sets the hash algorithm to be used before verifying the signature of the input hash algorithm value.
