Verifies a digital signature.
| VerifyData(Byte[], Byte[]) |
Verifies the digital signature of the specified data. |
| VerifyData(Stream, Byte[]) |
Verifies the digital signature of the specified data stream, reading to the end of the stream. |
| VerifyData(Byte[], Int32, Int32, Byte[]) |
Verifies a signature for the specified length of data, beginning at the specified offset. |

- data
- Byte[]
The data that was signed.
- signature
- Byte[]
The signature to be verified.
Returns
true if the signature is valid; otherwise, false.
Exceptions
data or signature is null.
Remarks
This method generates a signature for the given data by hashing the input data using the HashAlgorithm property, and then signing the result.
