Detailed Description

A chain of related Certificates.

CertificateChain is a list (a QList) of certificates that are related by the signature from one to another. If Certificate C signs Certificate B, and Certificate B signs Certificate A, then C, B and A form a chain.

The normal use of a CertificateChain is from a end-user Certificate (called the primary, equivalent to QList::first()) through some intermediate Certificates to some other Certificate (QList::last()), which might be a root Certificate Authority, but does not need to be.

You can build up the chain using normal QList operations, such as QList::append().

See also
QCA::CertificateCollection for an alternative way to represent a group of Certificates that do not necessarily have a chained relationship.

Constructor & Destructor Documentation

◆ CertificateChain() [1/2]

QCA::CertificateChain::CertificateChain ( )

Create an empty certificate chain.

Definition at line 1231 of file qca_cert.h.

◆ CertificateChain() [2/2]

QCA::CertificateChain::CertificateChain ( const Certificate & primary)

Create a certificate chain, starting at the specified certificate.

primarythe end-user certificate that forms one end of the chain

Definition at line 1241 of file qca_cert.h.

Member Function Documentation

◆ complete()

CertificateChain QCA::CertificateChain::complete ( const QList< Certificate > & issuers = QList<Certificate>(),
Validity * result = nullptr ) const

Complete a certificate chain for the primary certificate, using the rest of the certificates in the chain object, as well as those in issuers, as possible issuers in the chain.

If there are issuers missing, then the chain might be incomplete (at the worst case, if no issuers exist for the primary certificate, then the resulting chain will consist of just the primary certificate). Use the result argument to find out if there was a problem during completion. A result of ValidityGood means the chain was completed successfully.

The newly constructed CertificateChain is returned.

If the certificate chain is empty, then this will return an empty CertificateChain object.

◆ primary()

const Certificate & QCA::CertificateChain::primary ( ) const

Return the primary (end-user) Certificate.


Definition at line 1249 of file qca_cert.h.

◆ validate()

Validity QCA::CertificateChain::validate ( const CertificateCollection & trusted,
const QList< CRL > & untrusted_crls = QList<CRL>(),
UsageMode u = UsageAny,
ValidateFlags vf = ValidateAll ) const

Check the validity of a certificate chain.

untrusted_crlsa list of additional CRLs, not necessarily trusted
