Parameters

signerIdentifierType: SubjectIdentifierType

The scheme to use for identifying which signing certificate was used.

certificate: X509Certificate2

The certificate whose private key will be used to sign a message.

Remarks

This constructor results in the following default property values:

Property	Default value
DigestAlgorithm	2.16.840.1.101.3.4.2.1 (SHA-256)

CmsSigner(SubjectIdentifierType, X509Certificate2, AsymmetricAlgorithm)

Source:: CmsSigner.cs

Source:: CmsSigner.cs

Initializes a new instance of the CmsSigner class with a specified signer certificate, subject identifier type, and private key object.

public:
 CmsSigner(System::Security::Cryptography::Pkcs::SubjectIdentifierType signerIdentifierType, System::Security::Cryptography::X509Certificates::X509Certificate2 ^ certificate, System::Security::Cryptography::AsymmetricAlgorithm ^ privateKey);

public CmsSigner (System.Security.Cryptography.Pkcs.SubjectIdentifierType signerIdentifierType, System.Security.Cryptography.X509Certificates.X509Certificate2? certificate, System.Security.Cryptography.AsymmetricAlgorithm? privateKey);

public CmsSigner (System.Security.Cryptography.Pkcs.SubjectIdentifierType signerIdentifierType, System.Security.Cryptography.X509Certificates.X509Certificate2 certificate, System.Security.Cryptography.AsymmetricAlgorithm privateKey);

new System.Security.Cryptography.Pkcs.CmsSigner : System.Security.Cryptography.Pkcs.SubjectIdentifierType * System.Security.Cryptography.X509Certificates.X509Certificate2 * System.Security.Cryptography.AsymmetricAlgorithm -> System.Security.Cryptography.Pkcs.CmsSigner

Public Sub New (signerIdentifierType As SubjectIdentifierType, certificate As X509Certificate2, privateKey As AsymmetricAlgorithm)

Parameters

signerIdentifierType: SubjectIdentifierType

One of the enumeration values that specifies the scheme to use for identifying which signing certificate was used.

certificate: X509Certificate2

The certificate whose private key will be used to sign a message.

privateKey: AsymmetricAlgorithm

The private key object to use when signing the message.

Remarks

This constructor results in the following default property values:

Property	Default value
DigestAlgorithm	2.16.840.1.101.3.4.2.1 (SHA-256)
IncludeOption	X509IncludeOption.None if SignerIdentifierType is SubjectIdentifierType.NoSignature, X509IncludeOption.ExcludeRoot otherwise

This constructor does not validate that the privateKey parameter corresponds to the public key in certificate. If the keys don't match, the SignedCms class and ComputeCounterSignature(CmsSigner) method throw a CryptographicException during the signing process.

Applies to

certificate: X509Certificate2

The certificate whose private key will be used to sign a message.

privateKey: RSA

The private key object to use when signing the message.

signaturePadding: RSASignaturePadding

The RSA signature padding to use.
