参数

hash: Byte[]

已签名数据的哈希值。

signature: Byte[]

要验证的签名数据。

hashAlgorithm: HashAlgorithmName

用于创建哈希值的哈希算法。

padding: RSASignaturePadding

填充模式。

Boolean

如果签名有效，则为 true；否则为 false。

例外

NotImplementedException

派生方法必须重写此方法。

ArgumentNullException

hash 或 padding 为 null。

ArgumentException

hashAlgorithm.Name 为 null 或 Empty。

CryptographicException

padding 未知或不受此实现支持。
