AsymmetricSignatureDeformatter.VerifySignature 方法

定义

验证签名。Verifies the signature.

重载

VerifySignature(Byte[], Byte[])

在派生类中重写时,验证指定数据的签名。When overridden in a derived class, verifies the signature for the specified data.

VerifySignature(HashAlgorithm, Byte[])

通过指定的哈希值验证签名。Verifies the signature from the specified hash value.

VerifySignature(Byte[], Byte[])

在派生类中重写时,验证指定数据的签名。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

参数

rgbHash
Byte[]

rgbSignature 签名的数据。The data signed with rgbSignature.

rgbSignature
Byte[]

要为 rgbHash 验证的签名。The signature to be verified for rgbHash.

返回

Boolean

如果 rgbSignature 与使用指定的哈希算法和密钥在 rgbHash 上计算出的签名匹配,则为 true;否则为 falsetrue if rgbSignature matches the signature computed using the specified hash algorithm and key on rgbHash; otherwise, false.

注解

在调用此方法之前,必须指定公钥和哈希算法。You must specify a public key and a hash algorithm before calling this method.

适用于

VerifySignature(HashAlgorithm, Byte[])

通过指定的哈希值验证签名。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

参数

hash
HashAlgorithm

用于验证签名的哈希算法。The hash algorithm to use to verify the signature.

rgbSignature
Byte[]

要验证的签名。The signature to be verified.

返回

Boolean

如果签名对哈希有效,则为 true;否则为 falsetrue if the signature is valid for the hash; otherwise, false.

例外

hash 参数为 nullThe hash parameter is null.

注解

此方法设置在验证输入哈希算法值的签名之前要使用的哈希算法。This method sets the hash algorithm to be used before verifying the signature of the input hash algorithm value.
