VerifyHash(Byte[], Byte[], HashAlgorithmName, RSASignaturePadding)	使用指定的雜湊演算法和填補，並和提供的雜湊值比較，來為簽章判斷雜湊值，藉此驗證數位簽章是否有效。
VerifyHash(ReadOnlySpan<Byte>, ReadOnlySpan<Byte>, HashAlgorithmName, RSASignaturePadding)	使用指定的雜湊演算法和填補，並和提供的雜湊值比較，來為簽章判斷雜湊值，藉此驗證數位簽章是否有效。

參數

hash: Byte[]

已簽署資料的雜湊值。

signature: Byte[]

要驗證的簽章資料。

hashAlgorithm: HashAlgorithmName

用來建立該雜湊值的雜湊演算法。

padding: RSASignaturePadding

填補模式。

傳回

Boolean

如果簽章有效則為 true，否則為 false。

例外狀況

NotImplementedException

衍生的類別必須覆寫這個方法。

ArgumentNullException

hash 或 padding 為 null。

ArgumentException

hashAlgorithm.Name 是 null 或 Empty。

CryptographicException

padding 未知，或不支援此實作。
