| VerifyHash(Byte[], Byte[], HashAlgorithmName, RSASignaturePadding) |
Verifies data that was signed and already hashed with the specified algorithm and padding mode. |
| VerifyHash(ReadOnlySpan<Byte>, ReadOnlySpan<Byte>, HashAlgorithmName, RSASignaturePadding) |
Verifies that a digital signature is valid by determining the hash value in the signature using the specified hash algorithm and padding, and comparing it to the provided hash value. |
Verifies data that was signed and already hashed with the specified algorithm and padding mode.

- hash
- Byte[]
The hash to verify.
- signature
- Byte[]
The signature of the data.
- hashAlgorithm
- HashAlgorithmName
The hash algorithm name.
- padding
- RSASignaturePadding
The padding mode.
Returns
true if the signature verifies for the hash; otherwise, false.
Exceptions
padding does not equal Pkcs1 or Pss.
-or-
The signature is badly formatted. (In the .NET Framework 4.6 and 4.6.1 only; starting with the .NET Framework 4.6.2, the method returns false if a signature is badly formatted.
