DkimSigner(AsymmetricKeyParameter, String, String, DkimSignatureAlgorithm) Constructor

Initialize a new instance of the DkimSigner class.

Namespace: MimeKit.Cryptography
Assembly: MimeKit (in MimeKit.dll) Version: 4.7.1
Syntax
C#
Copy
public DkimSigner(
	AsymmetricKeyParameter key,
	string domain,
	string selector,
	DkimSignatureAlgorithm algorithm = DkimSignatureAlgorithm.RsaSha256
)

Parameters

key  AsymmetricKeyParameter
The signer's private key.
domain  String
The domain that the signer represents.
selector  String
The selector subdividing the domain.
algorithm  DkimSignatureAlgorithm  (Optional)
The signature algorithm.
Exceptions
ExceptionCondition
ArgumentNullException

key is null.

-or-

domain is null.

-or-

selector is null.

ArgumentExceptionkey is not a private key.

Creates a new DkimSigner.

Security note  Security Note
Due to the recognized weakness of the SHA-1 hash algorithm and the wide availability of the SHA-256 hash algorithm (it has been a required part of DKIM since it was originally standardized in 2007), it is recommended that RsaSha1 NOT be used.
