RSAOpenSsl()

Source:

RSAOpenSsl.cs

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

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.

RSAOpenSsl(Int32)

Source:

RSAOpenSsl.cs

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

public:
 RSAOpenSsl(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 RSAOpenSsl (int keySize);

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

Public Sub New (keySize As Integer)

Parameters

keySize

Int32

The size of the key to generate in bits.

Attributes

UnsupportedOSPlatformAttribute

Exceptions

CryptographicException

keySize is not valid.

RSAOpenSsl(IntPtr)

Source:

RSAOpenSsl.cs

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

public:
 RSAOpenSsl(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 RSAOpenSsl (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.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.

RSAOpenSsl(RSAParameters)

Source:

RSAOpenSsl.cs

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

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

[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 (System.Security.Cryptography.RSAParameters parameters);

[<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.RSAOpenSsl : System.Security.Cryptography.RSAParameters -> System.Security.Cryptography.RSAOpenSsl

Public Sub New (parameters As RSAParameters)

Parameters

parameters

RSAParameters

The parameters for the key.

Attributes

UnsupportedOSPlatformAttribute

Exceptions

CryptographicException

parameters is not a valid RSA key.

Remarks

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

RSAOpenSsl(SafeEvpPKeyHandle)

Source:

RSAOpenSsl.cs

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

public:
 RSAOpenSsl(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 RSAOpenSsl (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.RSAOpenSsl : System.Security.Cryptography.SafeEvpPKeyHandle -> System.Security.Cryptography.RSAOpenSsl

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.

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.
