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.

Member Enumeration Documentation

Section of the certificate that the constraint belongs in.

Enumerator:
KeyUsage  Stored in the key usage section.
ExtendedKeyUsage  Stored in the extended key usage section.


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:
known the type as part of the ConstraintTypeKnown enumerator

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  ) 

Standard copy constructor.

Parameters:
from the 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:
other the constraint type to compare with this constraint

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

Comparison operator.

Parameters:
other the constraint type to compare with this constraint

ConstraintType& QCA::ConstraintType::operator= ( const ConstraintType from  ) 

Standard assignment operator.

Parameters:
from the constraint type to assign from

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

Comparison operator.

Parameters:
other the constraint type to compare with this constraint

Section QCA::ConstraintType::section (  )  const

The section the constraint is part of.
