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

ConstraintType() [1/4]

QCA::ConstraintType::ConstraintType

(

)

Standard constructor.

ConstraintType() [2/4]

QCA::ConstraintType::ConstraintType

(

ConstraintTypeKnown

known

)

Construct a new constraint.

The section will be derived by known.

Parameters

known

the type as part of the ConstraintTypeKnown enumerator

ConstraintType() [3/4]

QCA::ConstraintType::ConstraintType	(	const QString &	id,
		Section	section )

Construct a new constraint.

Parameters

id	the type as an identifier string (OID or internal)
section	the section this type belongs in

See also

id

ConstraintType() [4/4]

QCA::ConstraintType::ConstraintType

(

const ConstraintType &

from

)

Standard copy constructor.

Parameters

from	the constraint type to copy from

Member Function Documentation

id()

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).

known()

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.

operator!=()

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

inline

Inequality operator.

Parameters

other

the constraint type to compare with this constraint

Definition at line 469 of file qca_cert.h.

operator<()

bool QCA::ConstraintType::operator<

(

const ConstraintType &

other

)

const

Comparison operator.

Parameters

other

the constraint type to compare with this constraint

operator=()

ConstraintType & QCA::ConstraintType::operator=

(

const ConstraintType &

from

)

Standard assignment operator.

Parameters

from	the constraint type to assign from

operator==()

bool QCA::ConstraintType::operator==

(

const ConstraintType &

other

)

const

Comparison operator.

Parameters

other

the constraint type to compare with this constraint

section()

Section QCA::ConstraintType::section

(

)

const

The section the constraint is part of.
