Detailed Description

Certificate constraint.

X.509 certificates can be constrained in their application - that is, some certificates can only be used for certain purposes. This class is used to identify an approved purpose for a certificate.

Note
It is common for a certificate to have more than one purpose.

Constructor & Destructor Documentation

QCA::ConstraintType::ConstraintType ( )

Standard constructor.

QCA::ConstraintType::ConstraintType ( ConstraintTypeKnown  known)

Construct a new constraint.

The section will be derived by known.

Parameters
knownthe type as part of the ConstraintTypeKnown enumerator
QCA::ConstraintType::ConstraintType ( const QString id,
Section  section 
)

Construct a new constraint.

Parameters
idthe type as an identifier string (OID or internal)
sectionthe section this type belongs in

id
QCA::ConstraintType::ConstraintType ( const ConstraintType from)

Standard copy constructor.

Parameters
fromthe constraint type to copy from

Member Function Documentation

QString QCA::ConstraintType::id ( ) const

The type as an identifier string.

For types that have OIDs, this function returns an OID in string form. For types that do not have OIDs, this function returns an internal identifier string whose first character is not a digit (this allows you to tell the difference between an OID and an internal identifier).

It is hereby stated that the KeyUsage bit fields shall use the internal identifier format "KeyUsage.[rfc field name]". For example, the keyEncipherment field would have the identifier "KeyUsage.keyEncipherment".

Applications should not store, use, or compare against internal identifiers unless the identifiers are explicitly documented (e.g. KeyUsage).

ConstraintTypeKnown QCA::ConstraintType::known ( ) const

The type as part of the ConstraintTypeKnown enumerator.

This function may return a value that does not exist in the enumerator. In that case, you may use id() to determine the type.

bool QCA::ConstraintType::operator!= ( const ConstraintType other) const
inline

Inequality operator.

Parameters
otherthe constraint type to compare with this constraint

Definition at line 469 of file qca_cert.h.

bool QCA::ConstraintType::operator< ( const ConstraintType other) const

Comparison operator.

Parameters
otherthe constraint type to compare with this constraint
ConstraintType& QCA::ConstraintType::operator= ( const ConstraintType from)

Standard assignment operator.

Parameters
fromthe constraint type to assign from
bool QCA::ConstraintType::operator== ( const ConstraintType other) const

Comparison operator.

Parameters
otherthe constraint type to compare with this constraint
Section QCA::ConstraintType::section ( ) const

The section the constraint is part of.
