CRYPTPLUG is an independent cryptography plug-in API developed for Sphinx-enabeling KMail and Mutt. CRYPTPLUG was designed for the Aegypten project, but it may be used by 3rd party developers as well to design pluggable crypto backends for the above mentioned MUAs. \note All string parameters appearing in this API are to be interpreted as UTF-8 encoded. \see pgpplugin.c \see gpgplugin.c */ /*! \defgroup groupGeneral Loading and Unloading the Plugin, General Functionality The functions in this section are used for loading and unloading plugins. Note that the actual locating of the plugin and the loading and unloading of the dynamic library is not covered here; this is MUA-specific code for which support code might already exist in the programming environments. */ /*! \defgroup groupDisplay Graphical Display Functionality The functions in this section return stationery that the MUAs can use in order to display security functionality graphically. This can be toolbar icons, shortcuts, tooltips, etc. Not all MUAs will use all this functionality. */ /*! \defgroup groupConfig Configuration Support The functions in this section provide the necessary functionality to configure the security functionality as well as to query configuration settings. Since all configuration settings will not be saved with the plugin, but rather with the MUA, there are also functions to set configuration settings programmatically; these will be used on startup of the plugin when the MUA transfers the configuration values it has read into the plugin. Usually, the functions to query and set the configuration values are not needed for anything but saving to and restoring from configuration files. */ /*! \defgroup groupConfigSign Signature Configuration \ingroup groupConfig The functions in this section provide the functionality to configure signature handling and set and query the signature configuration. */ /*! \defgroup groupConfigCrypt Encryption Configuration \ingroup groupConfig The functions in this section provide the functionality to configure encryption handling and set and query the encryption configuration. \note Whenever the term encryption is used here, it is supposed to mean both encryption and decryption, unless otherwise specified. */ /*! \defgroup groupConfigDir Directory Service Configuration \ingroup groupConfig This section contains messages for configuring the directory service. */ /*! \defgroup groupCertHand Certificate Handling The following methods are used to maintain and query certificates. */ /*! \defgroup groupSignAct Signature Actions This section describes methods that are used for working with signatures. */ /*! \defgroup groupCryptAct Encryption and Decryption The following methods are used to encrypt and decrypt email messages. */ /*! \defgroup groupCertAct Certificate Handling Actions The functions in this section provide local certificate management. */ /*! \defgroup groupCRLAct CRL Handling Actions This section describes functions for managing CRLs. */ // dummy values: typedef enum { CryptPlugFeat_undef = 0, CryptPlugFeat_SignMessages = 1, CryptPlugFeat_VerifySignatures = 2, CryptPlugFeat_EncryptMessages = 3, CryptPlugFeat_DecryptMessages = 4 // more to follow ... } Feature; // dummy values typedef enum { PinRequest_undef = 0, PinRequest_Always = 1, PinRequest_WhenAddingCerts = 2, PinRequest_AlwaysWhenSigning = 3, PinRequest_OncePerSession = 4, PinRequest_AfterMinutes = 5 } PinRequests; // dummy values: typedef enum { SendCert_undef = 0, SendCert_DontSend = 1, SendCert_SendOwn = 2, SendCert_SendChainWithoutRoot = 3, SendCert_SendChainWithRoot = 4 } SendCertificates; // dummy values: typedef enum { SignAlg_undef = 0, SignAlg_SHA1 = 1 } SignatureAlgorithm; typedef enum { EncryptAlg_undef = 0, EncryptAlg_RSA = 1, EncryptAlg_SHA1 = 2, EncryptAlg_TripleDES = 3 } EncryptionAlgorithm; typedef enum { SignEmail_undef = 0, SignEmail_SignAll = 1, SignEmail_Ask = 2, SignEmail_DontSign = 3 } SignEmail; typedef enum { EncryptEmail_undef = 0, EncryptEmail_EncryptAll = 1, EncryptEmail_Ask = 2, EncryptEmail_DontEncrypt = 3 } EncryptEmail; typedef enum { CertSrc_undef = 0, CertSrc_Server = 1, CertSrc_Local = 2, CertSrc_ServerLocal = CertSrc_Server | CertSrc_Local } CertificateSource; /*! \ingroup groupGeneral \brief This function sets up all internal structures.
