Detailed Description

Certificate chain and private key pair.

KeyBundle is essentially a convience class that holds a certificate chain and an associated private key. This class has a number of methods that make it particularly suitable for accessing a PKCS12 (.p12) format file, however it can be used as just a container for a Certificate, its associated PrivateKey and optionally additional X.509 Certificate that form a chain.

For more information on PKCS12 "Personal Information Exchange Syntax Standard", see ftp://ftp.rsasecurity.com/pub/pkcs/pkcs-12/pkcs-12v1.pdf.

Constructor & Destructor Documentation

KeyBundle() [1/3]

QCA::KeyBundle::KeyBundle

(

)

Create an empty KeyBundle.

KeyBundle() [2/3]

QCA::KeyBundle::KeyBundle ( const QString & fileName, const SecureArray & passphrase = SecureArray() )

explicit

Create a KeyBundle from a PKCS12 (.p12) encoded file.

This constructor requires appropriate plugin (provider) support. You must check for the "pkcs12" feature before using this constructor.

Parameters

fileName	the name of the file to read from
passphrase	the passphrase that is applicable to the file

See also

fromFile for a more flexible version of the same capability.

Note

This synchronous operation may require event handling, and so it must not be called from the same thread as an EventHandler.

KeyBundle() [3/3]

QCA::KeyBundle::KeyBundle

(

const KeyBundle &

from

)

Standard copy constructor.

Parameters

from	the KeyBundle to use as source

Member Function Documentation

certificateChain()

CertificateChain QCA::KeyBundle::certificateChain

(

)

const

The public certificate part of this bundle.

See also

setCertificateChainAndKey

fromArray()

static KeyBundle QCA::KeyBundle::fromArray ( const QByteArray & a, const SecureArray & passphrase = SecureArray(), ConvertResult * result = nullptr, const QString & provider = QString() )

static

   Import the key bundle from an array in PKCS12 format

   This method requires appropriate plugin (provider)
   support - you must check for the "pkcs12" feature,
   as shown below.

   \code

if( QCA::isSupported("pkcs12") ) { // can use I/O bundle = QCA::KeyBundle::fromArray( array, "pass phrase" ); } else { // not possible to use I/O }

Parameters

a	the array to import from
passphrase	the passphrase for the encoded bundle
result	pointer to the result of the import process
provider	the provider to use, if a specific provider is required

See also

QCA::KeyLoader for an asynchronous loader approach.

Note

This synchronous operation may require event handling, and so it must not be called from the same thread as an EventHandler.

fromFile()

static KeyBundle QCA::KeyBundle::fromFile ( const QString & fileName, const SecureArray & passphrase = SecureArray(), ConvertResult * result = nullptr, const QString & provider = QString() )

static

   Import the key bundle from a file in PKCS12 (.p12) format

   This method requires appropriate plugin (provider)
   support - you must check for the "pkcs12" feature,
   as shown below.

   \code

if( QCA::isSupported("pkcs12") ) { // can use I/O bundle = QCA::KeyBundle::fromFile( filename, "pass phrase" ); } else { // not possible to use I/O }

Parameters

fileName	the name of the file to read from
passphrase	the passphrase for the encoded bundle
result	pointer to the result of the import process
provider	the provider to use, if a specific provider is required

See also

QCA::KeyLoader for an asynchronous loader approach.

Note

This synchronous operation may require event handling, and so it must not be called from the same thread as an EventHandler.

isNull()

bool QCA::KeyBundle::isNull

(

)

const

Test if this key is empty (null)

name()

QString QCA::KeyBundle::name

(

)

const

The name associated with this key.

This is also known as the "friendly name", and if present, is typically suitable to be displayed to the user.

See also

setName

operator=()

KeyBundle & QCA::KeyBundle::operator=

(

const KeyBundle &

from

)

Standard assignment operator.

Parameters

from	the KeyBundle to use as source

privateKey()

PrivateKey QCA::KeyBundle::privateKey

(

)

const

The private key part of this bundle.

See also

setCertificateChainAndKey

setCertificateChainAndKey()

void QCA::KeyBundle::setCertificateChainAndKey	(	const CertificateChain &	c,
		const PrivateKey &	key )

Set the public certificate and private key.

Parameters

c	the CertificateChain containing the public part of the Bundle
key	the private key part of the Bundle

See also

privateKey, certificateChain for getters

setName()

void QCA::KeyBundle::setName

(

const QString &

s

)

Specify the name of this bundle.

Parameters

s	the name to use

toArray()

QByteArray QCA::KeyBundle::toArray	(	const SecureArray &	passphrase,
		const QString &	provider = QString() ) const

   Export the key bundle to an array in PKCS12 format.

   This method requires appropriate plugin (provider)
   support - you must check for the "pkcs12" feature,
   as shown below.

   \code

if( QCA::isSupported("pkcs12") ) { // can use I/O byteArray = bundle.toArray( "pass phrase" ); } else { // not possible to use I/O }

Parameters

passphrase	the passphrase to use to protect the bundle
provider	the provider to use, if a specific provider is required

toFile()

bool QCA::KeyBundle::toFile	(	const QString &	fileName,
		const SecureArray &	passphrase,
		const QString &	provider = QString() ) const

   Export the key bundle to a file in PKCS12 (.p12) format

   This method requires appropriate plugin (provider)
   support - you must check for the "pkcs12" feature,
   as shown below.

   \code

if( QCA::isSupported("pkcs12") ) { // can use I/O bool result = bundle.toFile( filename, "pass phrase" ); } else { // not possible to use I/O }

Parameters

fileName	the name of the file to save to
passphrase	the passphrase to use to protect the bundle
provider	the provider to use, if a specific provider is required
