ECDsaOpenSsl(IntPtr)	Initializes a new instance of the ECDsaOpenSsl class from an existing OpenSSL key represented as an EC_KEY*.

ECDsaOpenSsl()

Source:

ECDsaOpenSsl.cs

Initializes a new instance of the ECDsaOpenSsl class.

public:
 ECDsaOpenSsl();

[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 ECDsaOpenSsl ();

Public Sub New ()

Attributes

UnsupportedOSPlatformAttribute

Remarks

This constructor does not generate a new public/private keypair immediately. This constructor sets the KeySize property to 521 and when a key is needed, the saved size is used to identify the target curve. If a key is loaded via the ImportParameters method or another key import method, the key size from this constructor has no meaning.

ECDsaOpenSsl(Int32)

Source:

ECDsaOpenSsl.cs

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

public:
 ECDsaOpenSsl(int keySize);

[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 ECDsaOpenSsl (int keySize);

[<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.ECDsaOpenSsl : int -> System.Security.Cryptography.ECDsaOpenSsl

Public Sub New (keySize As Integer)

Parameters

keySize

Int32

The size of the key. Valid key sizes are 256, 384, and 521 bits.

Attributes

UnsupportedOSPlatformAttribute

Exceptions

CryptographicException

keySize specifies an invalid length.

Remarks

This constructor does not generate a new public/private keypair immediately. This constructor sets the KeySize property to the provided value and when a key is needed, the saved size is used to identify the target curve. If a key is loaded via the ImportParameters method or another key import method, the key size from this constructor has no meaning.

ECDsaOpenSsl(IntPtr)

Source:

ECDsaOpenSsl.cs

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

public:
 ECDsaOpenSsl(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 ECDsaOpenSsl (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.ECDsaOpenSsl : nativeint -> System.Security.Cryptography.ECDsaOpenSsl

Public Sub New (handle As IntPtr)

Parameters

handle

IntPtr

nativeint

The OpenSSL EC_KEY* value to use as the key.

Attributes

UnsupportedOSPlatformAttribute

Exceptions

ArgumentException

handle is Zero.

CryptographicException

handle is not a valid EC_KEY*.

Remarks

Important

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

ECDsaOpenSsl(ECCurve)

Source:

ECDsaOpenSsl.cs

Initializes a new instance of the ECDsaOpenSsl class and generates a new key on the specified curve.

public:
 ECDsaOpenSsl(System::Security::Cryptography::ECCurve curve);

[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 ECDsaOpenSsl (System.Security.Cryptography.ECCurve curve);

[<System.Runtime.Versioning.UnsupportedOSPlatform("android")>]

Parameters

curve

ECCurve

The curve used to generate an ephemeral public/private key pair.

Attributes

UnsupportedOSPlatformAttribute

Exceptions

CryptographicException

curve does not validate.

ArgumentNullException

curve is null.

ECDsaOpenSsl(SafeEvpPKeyHandle)

Source:

ECDsaOpenSsl.cs

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

public:
 ECDsaOpenSsl(System::Security::Cryptography::SafeEvpPKeyHandle ^ pkeyHandle);

[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 ECDsaOpenSsl (System.Security.Cryptography.SafeEvpPKeyHandle pkeyHandle);

[<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.ECDsaOpenSsl : System.Security.Cryptography.SafeEvpPKeyHandle -> System.Security.Cryptography.ECDsaOpenSsl

Public Sub New (pkeyHandle As SafeEvpPKeyHandle)

Parameters

pkeyHandle

SafeEvpPKeyHandle

The OpenSSL EVP_PKEY* value to use as the key, represented as a SafeEvpPKeyHandle.

Attributes

UnsupportedOSPlatformAttribute

Exceptions

ArgumentException

pkeyHandle represents an invalid handle.

ArgumentNullException

pkeyHandle is null.

CryptographicException

pkeyHandle does not represent a elliptic curve (EC) key.

Remarks

In .NET 9 and later versions, external modifications of pkeyHandle also affect the handle stored in the instance that this constructor creates.

Important

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