DSAOpenSsl()	Initializes a new instance of the DSAOpenSsl class with a default key size of 2048 bits.
DSAOpenSsl(Int32)	Initializes a new instance of the DSAOpenSsl class with a specified key size.
DSAOpenSsl(IntPtr)	Initializes a new instance of the DSAOpenSsl class from an existing OpenSSL key represented as a DSA*.

DSAOpenSsl()

Source:

DSAOpenSsl.cs

Initializes a new instance of the DSAOpenSsl class with a default key size of 2048 bits.

public:
 DSAOpenSsl();

[System.Runtime.Versioning.UnsupportedOSPlatform("android")]
[System.Runtime.Versioning.UnsupportedOSPlatform("browser")]
[System.Runtime.Versioning.UnsupportedOSPlatform("ios")]
[System.Runtime.Versioning.UnsupportedOSPlatform("tvos")]
[System.Runtime.Versioning.UnsupportedOSPlatform("windows")]
public DSAOpenSsl ();

Public Sub New ()

Attributes

UnsupportedOSPlatformAttribute

Remarks

This constructor does not generate a new DSA public/private keypair immediately, it just sets the size which will be used to generate a key when one is needed. If key is loaded via the ImportParameters method, or other key import method, the key size from this constructor has no meaning.

DSAOpenSsl(Int32)

Source:

DSAOpenSsl.cs

Initializes a new instance of the DSAOpenSsl class with a specified key size.

public:
 DSAOpenSsl(int keySize);

[System.Runtime.Versioning.UnsupportedOSPlatform("browser")]
[System.Runtime.Versioning.UnsupportedOSPlatform("ios")]

[<System.Runtime.Versioning.UnsupportedOSPlatform("windows")>]
new System.Security.Cryptography.DSAOpenSsl : int -> System.Security.Cryptography.DSAOpenSsl

Public Sub New (keySize As Integer)

Parameters

keySize

Int32

The size of the key to generate, when a key is needed.

Attributes

UnsupportedOSPlatformAttribute

Exceptions

CryptographicException

The keySize value is not supported by this implementation.

Remarks

This constructor does not generate a new DSA public/private keypair immediately, it just sets the size which will be used to generate a key when one is needed. If key is loaded via the ImportParameters method, or other key import method, the keySize provided to this constructor has no meaning.

DSAOpenSsl(IntPtr)

Source:

DSAOpenSsl.cs

Initializes a new instance of the DSAOpenSsl class from an existing OpenSSL key represented as a DSA*.

public:
 DSAOpenSsl(IntPtr handle);

[System.Runtime.Versioning.UnsupportedOSPlatform("android")]
[System.Runtime.Versioning.UnsupportedOSPlatform("browser")]
[System.Runtime.Versioning.UnsupportedOSPlatform("ios")]
[System.Runtime.Versioning.UnsupportedOSPlatform("tvos")]
[System.Runtime.Versioning.UnsupportedOSPlatform("windows")]
public DSAOpenSsl (IntPtr handle);

[<System.Runtime.Versioning.UnsupportedOSPlatform("android")>]
[<System.Runtime.Versioning.UnsupportedOSPlatform("browser")>]
[<System.Runtime.Versioning.UnsupportedOSPlatform("ios")>]
[<System.Runtime.Versioning.UnsupportedOSPlatform("tvos")>]
[<System.Runtime.Versioning.UnsupportedOSPlatform("windows")>]
new System.Security.Cryptography.DSAOpenSsl : nativeint -> System.Security.Cryptography.DSAOpenSsl

Public Sub New (handle As IntPtr)

Parameters

handle

IntPtr

nativeint

The OpenSSL DSA* value to use as the key.

Attributes

UnsupportedOSPlatformAttribute

Exceptions

ArgumentException

handle is Zero.

CryptographicException

handle is not a valid DSA*.

Remarks

Important

OpenSSL supports multiple library versions being loaded within the same process. Before calling this constructor, verify your pointer value came from the same version of OpenSSL that this class uses. For more information, see OpenSslVersion.

DSAOpenSsl(DSAParameters)

Source:

DSAOpenSsl.cs

[System.Runtime.Versioning.UnsupportedOSPlatform("android")]
[System.Runtime.Versioning.UnsupportedOSPlatform("browser")]
[System.Runtime.Versioning.UnsupportedOSPlatform("ios")]
