RSACng.VerifyHash(Byte[], Byte[], HashAlgorithmName, RSASignaturePadding) 方法

定義

命名空間:
System.Security.Cryptography
組件:
System.Security.Cryptography.Cng.dll
組件:
System.Core.dll

驗證已簽署且已使用指定演算法和填補模式雜湊處理的資料。Verifies data that was signed and already hashed with the specified algorithm and padding mode.

public:
 override bool VerifyHash(cli::array <System::Byte> ^ hash, cli::array <System::Byte> ^ signature, System::Security::Cryptography::HashAlgorithmName hashAlgorithm, System::Security::Cryptography::RSASignaturePadding ^ padding);
public override bool VerifyHash (byte[] hash, byte[] signature, System.Security.Cryptography.HashAlgorithmName hashAlgorithm, System.Security.Cryptography.RSASignaturePadding padding);
override this.VerifyHash : byte[] * byte[] * System.Security.Cryptography.HashAlgorithmName * System.Security.Cryptography.RSASignaturePadding -> bool
Public Overrides Function VerifyHash (hash As Byte(), signature As Byte(), hashAlgorithm As HashAlgorithmName, padding As RSASignaturePadding) As Boolean

參數

hash
Byte[]

要驗證的雜湊。The hash to verify.

signature
Byte[]

資料的簽章。The signature of the data.

hashAlgorithm
HashAlgorithmName

雜湊演算法名稱。The hash algorithm name.

padding
RSASignaturePadding

填補模式。The padding mode.

傳回

Boolean

如果雜湊的簽章驗證無誤，則為 true；否則為 false。true if the signature verifies for the hash; otherwise, false.

例外狀況

ArgumentNullException

hash 為 null。hash is null.

-或--or- signature 為 null。signature is null.

-或--or- padding 為 null。padding is null.

ArgumentException

hashAlgorithm 的 Name 屬性值為 null 或 Empty。The value of the Name property of hashAlgorithm is null or Empty.

CryptographicException

padding 不等於 Pkcs1 或 Pss。padding does not equal Pkcs1 or Pss.

-或--or- 簽章的格式不正確。The signature is badly formatted. 僅限 .NET Framework 4.6.NET Framework 4.6 和 4.6.1；從 .NET Framework 4.6.2.NET Framework 4.6.2 開始，如果簽章的格式不正確，此方法會傳回 false。(In the .NET Framework 4.6.NET Framework 4.6 and 4.6.1 only; starting with the .NET Framework 4.6.2.NET Framework 4.6.2, the method returns false if a signature is badly formatted.
