MessageSigner Class

Represents the utility which can be used to sign arbitrary data or verify existing signatures by using asymmetric encryption.

Definition

Namespace: SysadminsLV.PKI.Tools.MessageOperations
Assembly: SysadminsLV.PKI.Win (in SysadminsLV.PKI.Win.dll) Version: 4.0.1.0 (4.0.1.0)

C#

public class MessageSigner : ICryptSigner, 
	IDisposable

VB

Public Class MessageSigner
	Implements ICryptSigner, IDisposable

C++

public ref class MessageSigner : ICryptSigner, 
	IDisposable

F#

type MessageSigner = 
    class
        interface ICryptSigner
        interface IDisposable
    end

Inheritance: Object MessageSigner

Implements: ICryptSigner, IDisposable

Remarks

This class implements IDisposable interface. It is recommended to wrap this class in using statement to automatically release unmanaged resources during signing procedure.

Constructors

MessageSigner(X509Certificate2)	Initializes a new instance of the MessageSigner class from signer certificate and default hash algorithm. Default hash algorithm is SHA256.
MessageSigner(X509Certificate2, Oid2)	Initializes a new instance of the MessageSigner class from signer certificate and client-provided hash algorithm.

Properties

HashingAlgorithm	Gets or sets the hashing algorithm that is used to calculate the hash during signing or signature verification processes.
PaddingScheme	Gets or sets signature padding scheme for RSA signature creation and validation. Default is PKCS1.
PssSaltByteCount	Gets or sets the size, in bytes, of the random salt to use for the PSS padding. Default value matches the hash output length: 16 bytes for MD5, 20 bytes for SHA1, 32 bytes for SHA256, 48 bytes for SHA384 and 64 bytes for SHA512 hashing algorithm.
PublicKeyAlgorithm	Gets public key algorithm.
SignatureAlgorithm	Gets resulting signature algorithm identifier.
SignerCertificate	Gets the certificate associated with the current instance of MessageSigner.
