Assembly: mscorlib (in mscorlib.dll)
The DSASignatureDeformatter type exposes the following members.
| Name | Description | |
|---|---|---|
![]() | DSASignatureDeformatter() | Initializes a new instance of the DSASignatureDeformatter class. |
![]() | DSASignatureDeformatter(AsymmetricAlgorithm) | Initializes a new instance of the DSASignatureDeformatter class with the specified key. |
| Name | Description | |
|---|---|---|
![]() | Equals(Object) | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |
![]() | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
![]() | GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
![]() | GetType | Gets the Type of the current instance. (Inherited from Object.) |
![]() | MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
![]() | SetHashAlgorithm | Specifies the hash algorithm for the Digital Signature Algorithm (DSA) signature deformatter. (Overrides AsymmetricSignatureDeformatter::SetHashAlgorithm(String).) |
![]() | SetKey | Specifies the key to be used for the Digital Signature Algorithm (DSA) signature deformatter. (Overrides AsymmetricSignatureDeformatter::SetKey(AsymmetricAlgorithm).) |
![]() | ToString | Returns a string that represents the current object. (Inherited from Object.) |
![]() | VerifySignature(array<Byte>, array<Byte>) | Verifies the Digital Signature Algorithm (DSA) signature on the data. (Overrides AsymmetricSignatureDeformatter::VerifySignature(array<Byte>, array<Byte>).) |
![]() | VerifySignature(HashAlgorithm, array<Byte>) | Verifies the signature from the specified hash value. (Inherited from AsymmetricSignatureDeformatter.) |
