Description

TlsDatabase is used to lookup certificates and other information from a certificate or key store. It is an abstract base class which TLS library specific subtypes override.

Most common client applications will not directly interact with TlsDatabase. It is used internally by TlsConnection.

Since: 2.30

Methods

createCertificateHandle

tlsDatabaseCreateCertificateHandle Source #

Arguments

:: (HasCallStack, MonadIO m, IsTlsDatabase a, IsTlsCertificate b)
=> a	`self`: a `TlsDatabase`
-> b	`certificate`: certificate for which to create a handle.
-> m (Maybe Text)	Returns: a newly allocated string containing the handle.

Create a handle string for the certificate. The database will only be able to create a handle for certificates that originate from the database. In cases where the database cannot create a handle for a certificate, Nothing will be returned.

This handle should be stable across various instances of the application, and between applications. If a certificate is modified in the database, then it is not guaranteed that this handle will continue to point to it.

lookupCertificateForHandle

tlsDatabaseLookupCertificateForHandle Source #

Arguments

:: (HasCallStack, MonadIO m, IsTlsDatabase a, IsTlsInteraction b, IsCancellable c)
=> a	`self`: a `TlsDatabase`
-> Text	`handle`: a certificate handle
-> Maybe b	`interaction`: used to interact with the user if necessary
-> TlsDatabaseLookupFlags	`flags`: Flags which affect the lookup.
-> Maybe c	`cancellable`: a `Cancellable`, or `Nothing`
-> m (Maybe TlsCertificate)	Returns: a newly allocated `TlsCertificate`, or `Nothing`. Use `objectUnref` to release the certificate. (Can throw `GError`)

Lookup a certificate by its handle.

The handle should have been created by calling tlsDatabaseCreateCertificateHandle on a TlsDatabase object of the same TLS backend. The handle is designed to remain valid across instantiations of the database.

If the handle is no longer valid, or does not point to a certificate in this database, then Nothing will be returned.

This function can block, use tlsDatabaseLookupCertificateForHandleAsync to perform the lookup operation asynchronously.

-> TlsDatabaseLookupFlags	`flags`: Flags which affect the lookup.
-> Maybe c	`cancellable`: a `Cancellable`, or `Nothing`
-> Maybe AsyncReadyCallback	`callback`: callback to call when the operation completes
-> m ()

tlsDatabaseVerifyChain Source #

Arguments

-> Maybe e	`cancellable`: a `Cancellable`, or `Nothing`
-> m [TlsCertificateFlags]	Returns: the appropriate `TlsCertificateFlags` which represents the result of verification. (Can throw `GError`)

Determines the validity of a certificate chain after looking up and adding any missing certificates to the chain.

chain is a chain of TlsCertificate objects each pointing to the next certificate in the chain by its TlsCertificate:issuer property. The chain may initially consist of one or more certificates. After the verification process is complete, chain may be modified by adding missing certificates, or removing extra certificates. If a certificate anchor was found, then it is added to the chain.

purpose describes the purpose (or usage) for which the certificate is being used. Typically purpose will be set to TLS_DATABASE_PURPOSE_AUTHENTICATE_SERVER which means that the certificate is being used to authenticate a server (and we are acting as the client).

The identity is used to check for pinned certificates (trust exceptions) in the database. These will override the normal verification process on a host by host basis.

Currently there are no flags, and TlsDatabaseVerifyFlagsNone should be used.

If chain is found to be valid, then the return value will be 0. If chain is found to be invalid, then the return value will indicate the problems found. If the function is unable to determine whether chain is valid or not (eg, because cancellable is triggered before it completes) then the return value will be TlsCertificateFlagsGenericError and error will be set accordingly. error is not set when chain is successfully analyzed but found to be invalid.

This function can block, use tlsDatabaseVerifyChainAsync to perform the verification operation asynchronously.
