public ref class DSASignatureFormatter : AsymmetricSignatureFormatter

NameDescription
System_CAPS_pubmethodDSASignatureFormatter()

Initializes a new instance of the DSASignatureFormatter class.

System_CAPS_pubmethodDSASignatureFormatter(AsymmetricAlgorithm^)

Initializes a new instance of the DSASignatureFormatter class with the specified key.

NameDescription
System_CAPS_pubmethodCreateSignature(array<Byte>^)

Creates the Digital Signature Algorithm (DSA) PKCS #1 signature for the specified data.(Overrides AsymmetricSignatureFormatter::CreateSignature(array<Byte>^).)

System_CAPS_pubmethodCreateSignature(HashAlgorithm^)

Creates the signature from the specified hash value.(Inherited from AsymmetricSignatureFormatter.)

System_CAPS_pubmethodEquals(Object^)

Determines whether the specified object is equal to the current object.(Inherited from Object.)

System_CAPS_protmethodFinalize()

Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.)

System_CAPS_pubmethodGetHashCode()

Serves as the default hash function. (Inherited from Object.)

System_CAPS_pubmethodGetType()

Gets the Type of the current instance.(Inherited from Object.)

System_CAPS_protmethodMemberwiseClone()

Creates a shallow copy of the current Object.(Inherited from Object.)

System_CAPS_pubmethodSetHashAlgorithm(String^)

Specifies the hash algorithm for the Digital Signature Algorithm (DSA) signature formatter.(Overrides AsymmetricSignatureFormatter::SetHashAlgorithm(String^).)

System_CAPS_pubmethodSetKey(AsymmetricAlgorithm^)

Specifies the key to be used for the Digital Signature Algorithm (DSA) signature formatter.(Overrides AsymmetricSignatureFormatter::SetKey(AsymmetricAlgorithm^).)

System_CAPS_pubmethodToString()

Returns a string that represents the current object.(Inherited from Object.)
