| VerifySignature(ReadOnlySpan<Byte>, ReadOnlySpan<Byte>, DSASignatureFormat) |
Verifies that a digital signature is valid for the provided hash. |
| VerifySignature(Byte[], Byte[]) |
When overridden in a derived class, verifies the DSA signature for the specified data. |
| VerifySignature(ReadOnlySpan<Byte>, ReadOnlySpan<Byte>) |
Verifies that a digital signature is valid for a provided data hash. |
| VerifySignature(Byte[], Byte[], DSASignatureFormat) |
Verifies that a digital signature is valid for the provided hash. |

- hash
- ReadOnlySpan<Byte>
The signed hash.
- signature
- ReadOnlySpan<Byte>
The signature to verify.
- signatureFormat
- DSASignatureFormat
The encoding format for signature.
Returns
true if the digital signature is valid for the provided data; otherwise, false.
Exceptions
signatureFormat is not a known format.
An error occurred in the verification operation.

When overridden in a derived class, verifies the DSA signature for the specified data.
public:
abstract bool VerifySignature(cli::array <System::Byte> ^ rgbHash, cli::array <System::Byte> ^ rgbSignature);public abstract bool VerifySignature(byte[] rgbHash, byte[] rgbSignature);abstract member VerifySignature : byte[] * byte[] -> boolPublic MustOverride Function VerifySignature (rgbHash As Byte(), rgbSignature As Byte()) As BooleanParameters
- rgbHash
- Byte[]
The hash of the data signed with rgbSignature.
- rgbSignature
- Byte[]
The signature to be verified for rgbData.
Returns
true if rgbSignature matches the signature computed using the specified hash algorithm and key on rgbHash; otherwise, false.
Exceptions
The implementation type only supports legacy DSA (FIPS 186-2), and the hash value is not 20 bytes long.
-or-
Verifying the signature otherwise failed.

override this.VerifySignature : ReadOnlySpan<byte> * ReadOnlySpan<byte> -> boolPublic Overridable Function VerifySignature (hash As ReadOnlySpan(Of Byte), signature As ReadOnlySpan(Of Byte)) As BooleanParameters
- hash
- ReadOnlySpan<Byte>
The data hash to verify.
- signature
- ReadOnlySpan<Byte>
The signature to be verify.
Returns
true if the digital signature is valid for the hash; otherwise, false.
Exceptions
The implementation type only supports legacy DSA (FIPS 186-2), and the hash value is not 20 bytes long.
-or-
Verifying the signature otherwise failed.
Remarks
The default implementation of this method calls VerifySignature(Byte[], Byte[]) after copying the spans to arrays. Derived types should override this method to avoid the intermediate array creation.
