class System.Security.Cryptography.ECAlgorithm
Assembly: System.Security.Cryptography
Inheritance: object → AsymmetricAlgorithm → ECAlgorithm
Represents the abstract class from which elliptic-curve asymmetric algorithms can inherit.
Fields and Constants
protected
int
KeySizeValue
Represents the size, in bits, of the key modulus used by the asymmetric algorithm.
protected
KeySizes[]
LegalKeySizesValue
Specifies the key sizes that are supported by the asymmetric algorithm.
Properties
public
string
KeyExchangeAlgorithm
When overridden in a derived class, gets the name of the key exchange algorithm. Otherwise, throws an <see cref="T:System.NotImplementedException" /> .
public
int
KeySize
Gets or sets the size, in bits, of the key modulus used by the asymmetric algorithm.
public
KeySizes[]
LegalKeySizes
Gets the key sizes that are supported by the asymmetric algorithm.
public
string
SignatureAlgorithm
When implemented in a derived class, gets the name of the signature algorithm. Otherwise, always throws a <see cref="T:System.NotImplementedException" /> .
Methods
public
byte[]
ExportECPrivateKey() Returns A byte array containing the ECPrivateKey representation of this key.
Exports the current key in the ECPrivateKey format.
public
string
ExportECPrivateKeyPem() Returns A string containing the PEM-encoded ECPrivateKey.
Exports the current key in the ECPrivateKey format, PEM encoded.
public
ECParameters
ExportExplicitParameters(bool includePrivateParameters)
includePrivateParameters
<see langword="true" /> to include private parameters, otherwise, <see langword="false" /> .
Returns The exported explicit parameters.
When overridden in a derived class, exports the explicit <see cref="T:System.Security.Cryptography.ECParameters" /> for an ECCurve.
public
ECParameters
ExportParameters(bool includePrivateParameters)
includePrivateParameters
<see langword="true" /> to include private parameters, otherwise, <see langword="false" /> .
Returns The exported parameters.
When overridden in a derived class, exports the named or explicit <see cref="T:System.Security.Cryptography.ECParameters" /> for an ECCurve.
If the curve has a name, the Curve property will contain named curve parameters otherwise it will contain explicit parameters.
When overridden in a derived class, generates a new public/private keypair for the specified curve.
