Namespace: MimeKit.Cryptography
Assembly: MimeKit (in MimeKit.dll) Version: 4.7.1
Syntax
C#
Copy
public static Task<MultipartSigned> CreateAsync(
	CryptographyContext ctx,
	MailboxAddress signer,
	DigestAlgorithm digestAlgo,
	MimeEntity entity,
	CancellationToken cancellationToken = default
)

Parameters

ctx  CryptographyContext
The cryptography context to use for signing.
signer  MailboxAddress
The signer.
digestAlgo  DigestAlgorithm
The digest algorithm to use for signing.
entity  MimeEntity
The entity to sign.
cancellationToken  CancellationToken  (Optional)
The cancellation token.

Return Value

TaskMultipartSigned
A new MultipartSigned instance.
Exceptions
ExceptionCondition
ArgumentNullException

NotSupportedException The digestAlgo is not supported.
ObjectDisposedExceptionentity has been disposed.
OperationCanceledException The operation was canceled via the cancellation token.
CertificateNotFoundException A signing certificate could not be found for signer.
PrivateKeyNotFoundException The private key could not be found for signer.
