C# Class MimeKit.Cryptography.DefaultSecureMimeContext

A default SecureMimeContext implementation that uses an SQLite database as a certificate and private key store.

The default S/MIME context is designed to be usable on any platform where there exists a .NET runtime by storing certificates, CRLs, and (encrypted) private keys in a SQLite database.

Public Methods

Method	Description
DefaultSecureMimeContext ( IX509CertificateDatabase database ) : System	Initializes a new instance of the MimeKit.Cryptography.DefaultSecureMimeContext class. This constructor is useful for supplying a custom IX509CertificateDatabase.
DefaultSecureMimeContext ( string password ) : System	Initializes a new instance of the MimeKit.Cryptography.DefaultSecureMimeContext class. Allows the program to specify its own password for the default database. Requires linking with Mono.Data.Sqlite.
DefaultSecureMimeContext ( string fileName, string password ) : System	Initializes a new instance of the MimeKit.Cryptography.DefaultSecureMimeContext class. Allows the program to specify its own location for the SQLite database. If the file does not exist, it will be created and the necessary tables and indexes will be constructed. Requires linking with Mono.Data.Sqlite.
Import ( Stream stream, bool trusted ) : void	Imports a DER-encoded certificate stream. Imports all of the certificates in the DER-encoded stream.
Import ( Stream stream, string password ) : void	Imports certificates and keys from a pkcs12-encoded stream. Imports all of the certificates and keys from the pkcs12-encoded stream.
Import ( X509Certificate certificate ) : void	Imports a certificate. Imports the specified certificate into the database.
Import ( X509Crl crl ) : void	Imports a certificate revocation list. Imports the specified certificate revocation list.

Protected Methods

Method	Description
Dispose ( bool disposing ) : void	Releases the unmanaged resources used by the DefaultSecureMimeContext and optionally releases the managed resources. Releases the unmanaged resources used by the DefaultSecureMimeContext and optionally releases the managed resources.
GetCertificate ( IX509Selector selector ) : X509Certificate	Gets the X.509 certificate matching the specified selector. Gets the first certificate that matches the specified selector.
GetCertificateRevocationLists ( ) : IX509Store	Gets the certificate revocation lists. A Certificate Revocation List (CRL) is a list of certificate serial numbers issued by a particular Certificate Authority (CA) that have been revoked, either by the CA itself or by the owner of the revoked certificate.
GetCmsRecipient ( MailboxAddress mailbox ) : CmsRecipient	Gets the CmsRecipient for the specified mailbox. Constructs a CmsRecipient with the appropriate certificate and CmsRecipient.EncryptionAlgorithms for the specified mailbox. If the mailbox is a SecureMailboxAddress, the SecureMailboxAddress.Fingerprint property will be used instead of the mailbox address for database lookups.
GetCmsSigner ( MailboxAddress mailbox, DigestAlgorithm digestAlgo ) : CmsSigner	Gets the CmsSigner for the specified mailbox. Constructs a CmsSigner with the appropriate signing certificate for the specified mailbox. If the mailbox is a SecureMailboxAddress, the SecureMailboxAddress.Fingerprint property will be used instead of the mailbox address for database lookups.
GetIntermediateCertificates ( ) : IX509Store	Gets the intermediate certificates. An intermediate certificate is any certificate that exists between the root certificate issued by a Certificate Authority (CA) and the certificate at the end of the chain.
GetPrivateKey ( IX509Selector selector ) : AsymmetricKeyParameter	Gets the private key for the certificate matching the specified selector. Gets the private key for the first certificate that matches the specified selector.
GetTrustedAnchors ( ) : Org.BouncyCastle.Utilities.Collections.HashSet	Gets the trusted anchors. A trusted anchor is a trusted root-level X.509 certificate, generally issued by a Certificate Authority (CA).
UpdateSecureMimeCapabilities ( X509Certificate certificate, EncryptionAlgorithm algorithms, System.DateTime timestamp ) : void	Updates the known S/MIME capabilities of the client used by the recipient that owns the specified certificate. Updates the known S/MIME capabilities of the client used by the recipient that owns the specified certificate.
