AsymmetricSignatureDeformatter.VerifySignature Method

Definition

Namespace:

System.Security.Cryptography

Assembly:

System.Security.Cryptography.dll

Verifies the signature.

Overloads

VerifySignature(Byte[], Byte[])	When overridden in a derived class, verifies the signature for the specified data.
VerifySignature(HashAlgorithm, Byte[])	Verifies the signature from the specified hash value.

VerifySignature(Byte[], Byte[])

Source:

AsymmetricSignatureDeformatter.cs

When overridden in a derived class, verifies the signature for the specified data.

public:
 abstract bool VerifySignature(cli::array <System::Byte> ^ rgbHash, cli::array <System::Byte> ^ rgbSignature);

public abstract bool VerifySignature (byte[] rgbHash, byte[] rgbSignature);

abstract member VerifySignature : byte[] * byte[] -> bool

Public MustOverride Function VerifySignature (rgbHash As Byte(), rgbSignature As Byte()) As Boolean

Parameters

rgbHash

Byte[]

The data signed with rgbSignature.

rgbSignature

Byte[]

The signature to be verified for rgbHash.

Returns

Boolean

true if rgbSignature matches the signature computed using the specified hash algorithm and key on rgbHash; otherwise, false.

Remarks

You must specify a public key and a hash algorithm before calling this method.

VerifySignature(HashAlgorithm, Byte[])

Source:

AsymmetricSignatureDeformatter.cs

Verifies the signature from the specified hash value.

public:
 virtual bool VerifySignature(System::Security::Cryptography::HashAlgorithm ^ hash, cli::array <System::Byte> ^ rgbSignature);

public virtual bool VerifySignature (System.Security.Cryptography.HashAlgorithm hash, byte[] rgbSignature);

abstract member VerifySignature : System.Security.Cryptography.HashAlgorithm * byte[] -> bool
override this.VerifySignature : System.Security.Cryptography.HashAlgorithm * byte[] -> bool

Public Overridable Function VerifySignature (hash As HashAlgorithm, rgbSignature As Byte()) As Boolean

Parameters

hash

HashAlgorithm

The hash algorithm to use to verify the signature.

rgbSignature

Byte[]

The signature to be verified.

Returns

Boolean

true if the signature is valid for the hash; otherwise, false.

Exceptions

ArgumentNullException

The hash parameter is null.

Remarks

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