[HostProtectionAttribute(SecurityAction.LinkDemand, MayLeakOnAbort = true)]
public abstract class ECDsa : AsymmetricAlgorithm

NameDescription
System_CAPS_protmethodECDsa()

Initializes a new instance of the ECDsa class.

NameDescription
System_CAPS_pubpropertyKeyExchangeAlgorithm

Gets the name of the key exchange algorithm.(Overrides AsymmetricAlgorithm.KeyExchangeAlgorithm.)

System_CAPS_pubpropertyKeySize

Gets or sets the size, in bits, of the key modulus used by the asymmetric algorithm.(Inherited from AsymmetricAlgorithm.)

System_CAPS_pubpropertyLegalKeySizes

Gets the key sizes that are supported by the asymmetric algorithm.(Inherited from AsymmetricAlgorithm.)

System_CAPS_pubpropertySignatureAlgorithm

Gets the name of the signature algorithm.(Overrides AsymmetricAlgorithm.SignatureAlgorithm.)

NameDescription
System_CAPS_pubmethodClear()

Releases all resources used by the AsymmetricAlgorithm class.(Inherited from AsymmetricAlgorithm.)

System_CAPS_pubmethodSystem_CAPS_staticCreate()

Creates a new instance of the default implementation of the Elliptic Curve Digital Signature Algorithm (ECDSA).

System_CAPS_pubmethodSystem_CAPS_staticCreate(String)

Creates a new instance of the specified implementation of the Elliptic Curve Digital Signature Algorithm (ECDSA).

System_CAPS_pubmethodDispose()

Releases all resources used by the current instance of the AsymmetricAlgorithm class.(Inherited from AsymmetricAlgorithm.)

System_CAPS_protmethodDispose(Boolean)

Releases the unmanaged resources used by the AsymmetricAlgorithm class and optionally releases the managed resources.(Inherited from AsymmetricAlgorithm.)

System_CAPS_pubmethodEquals(Object)

Determines whether the specified object is equal to the current object.(Inherited from Object.)

Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.)

System_CAPS_pubmethodFromXmlString(String)

When overridden in a derived class, reconstructs an AsymmetricAlgorithm object from an XML string. Otherwise, throws a NotImplementedException.(Inherited from AsymmetricAlgorithm.)

System_CAPS_pubmethodGetHashCode()

Serves as the default hash function. (Inherited from Object.)

System_CAPS_pubmethodGetType()

Gets the Type of the current instance.(Inherited from Object.)

System_CAPS_protmethodHashData(Byte[], Int32, Int32, HashAlgorithmName)

When overridden in a derived class, computes the hash value of the specified portion of a byte array by using the specified hashing algorithm.

System_CAPS_protmethodHashData(Stream, HashAlgorithmName)

When overridden in a derived class, computes the hash value of the specified binary stream by using the specified hashing algorithm.

System_CAPS_protmethodMemberwiseClone()

Creates a shallow copy of the current Object.(Inherited from Object.)

System_CAPS_pubmethodSignData(Byte[], HashAlgorithmName)

Computes the hash value of the specified byte array using the specified hash algorithm and signs the resulting hash value.

Returns a string that represents the current object.(Inherited from Object.)

System_CAPS_pubmethodToXmlString(Boolean)

When overridden in a derived class, creates and returns an XML string representation of the current AsymmetricAlgorithm object. Otherwise, throws a NotImplementedException.(Inherited from AsymmetricAlgorithm.)

System_CAPS_pubmethodVerifyData(Byte[], Byte[], HashAlgorithmName)

Verifies that a digital signature is valid by calculating the hash value of the specified data using the specified hash algorithm and comparing it to the provided signature.

System_CAPS_pubmethodVerifyData(Byte[], Int32, Int32, Byte[], HashAlgorithmName)

Verifies that a digital signature is valid by calculating the hash value of the data in a portion of a byte array using the specified hash algorithm and comparing it to the provided signature.

System_CAPS_pubmethodVerifyData(Stream, Byte[], HashAlgorithmName)

Verifies that a digital signature is valid by calculating the hash value of the specified stream using the specified hash algorithm and comparing it to the provided signature.

System_CAPS_pubmethodVerifyHash(Byte[], Byte[])

Verifies a digital signature against the specified hash value.
