RSAOpenSsl()

Source:: RSAOpenSsl.cs

Source:: RSAOpenSsl.cs

Source:: RSAOpenSsl.cs

Initializes a new instance of the RSAOpenSsl class with a random 2048-bit key pair.

public:
 RSAOpenSsl();

public RSAOpenSsl ();

[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 RSAOpenSsl ();

Public Sub New ()

Attributes: UnsupportedOSPlatformAttribute

Remarks

This constructor does not generate a new public/private keypair immediately. This constructor sets the KeySize property to 2048 and when a key is needed, one is generated using the property value. If a key is loaded via the ImportParameters method or another key import method, the key size from this constructor has no meaning.

Applies to

Source:: RSAOpenSsl.cs

Source:: RSAOpenSsl.cs

Source:: RSAOpenSsl.cs

Initializes a new instance of the RSAOpenSsl class with a randomly generated key of the specified size.

The size of the key to generate in bits.

Attributes: UnsupportedOSPlatformAttribute

Exceptions

CryptographicException

keySize is not valid.

Applies to

RSAOpenSsl(IntPtr)

Source:: RSAOpenSsl.cs

Source:: RSAOpenSsl.cs

Source:: RSAOpenSsl.cs

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

public:
 RSAOpenSsl(IntPtr handle);

public RSAOpenSsl (IntPtr handle);

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

Public Sub New (handle As IntPtr)

Parameters

handle: IntPtr
nativeint

The OpenSSL RSA* value to use as the key.

Attributes: UnsupportedOSPlatformAttribute

Exceptions

CryptographicException

handle is not a valid RSA*.

ArgumentException

handle is invalid

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.

Applies to

RSAOpenSsl(RSAParameters)

Source:: RSAOpenSsl.cs

Source:: RSAOpenSsl.cs

Source:: RSAOpenSsl.cs

Initializes a new instance of the RSAOpenSsl class using specified key parameters.

public:
 RSAOpenSsl(System::Security::Cryptography::RSAParameters parameters);

public RSAOpenSsl (System.Security.Cryptography.RSAParameters parameters);

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

Public Sub New (parameters As RSAParameters)

Parameters

parameters: RSAParameters

The parameters for the key.

Remarks

This constructor is equivalent to using the default constructor and calling ImportParameters.

Applies to

[System.Runtime.Versioning.UnsupportedOSPlatform("ios")]
[System.Runtime.Versioning.UnsupportedOSPlatform("tvos")]
[System.Runtime.Versioning.UnsupportedOSPlatform("windows")]
public RSAOpenSsl (System.Security.Cryptography.SafeEvpPKeyHandle pkeyHandle);

new System.Security.Cryptography.RSAOpenSsl : System.Security.Cryptography.SafeEvpPKeyHandle -> System.Security.Cryptography.RSAOpenSsl

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

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

CryptographicException

pkeyHandle does not represent an RSA key.

ArgumentNullException

pkeyHandle is null

ArgumentException

pkeyHandle is invalid according to IsInvalid.

Remarks

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