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.

Definition at line 901 of file qca_cert.cpp.

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

Definition at line 906 of file qca_cert.cpp.

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

QCA::ConstraintType::ConstraintType

(

const ConstraintType &

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).

Definition at line 947 of file qca_cert.cpp.

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.

Definition at line 942 of file qca_cert.cpp.

bool QCA::ConstraintType::operator!=

(

const ConstraintType &

other

)

const [inline]

Inequality operator.

Parameters:

other

the constraint type to compare with this constraint

Definition at line 463 of file qca_cert.h.

bool QCA::ConstraintType::operator<

(

const ConstraintType &

other

)

const

Comparison operator.

Parameters:

other

the constraint type to compare with this constraint

Definition at line 952 of file qca_cert.cpp.

ConstraintType & QCA::ConstraintType::operator=

(

const ConstraintType &

from

)

Standard assignment operator.

Parameters:

from

the constraint type to assign from

Definition at line 931 of file qca_cert.cpp.

bool QCA::ConstraintType::operator==

(

const ConstraintType &

other

)

const

Comparison operator.

Parameters:

other

the constraint type to compare with this constraint

Definition at line 975 of file qca_cert.cpp.

ConstraintType::Section QCA::ConstraintType::section

(

)

const

The section the constraint is part of.

Definition at line 937 of file qca_cert.cpp.
