Detailed Description

Public key implementation provider base.

Note: This class is part of the provider plugin interface and should not be used directly by applications. You probably want PKey, PublicKey, or PrivateKey instead.

Constructor & Destructor Documentation

◆ PKeyBase()

QCA::PKeyBase::PKeyBase	(	Provider *	p,
		const QString &	type )

Standard constructor.

Parameters

p	the Provider associated with this context
type	type of key provided by this context

Member Function Documentation

◆ bits()

virtual int QCA::PKeyBase::bits ( ) const

pure virtual

Returns the number of bits in the key.

◆ canExport()

virtual bool QCA::PKeyBase::canExport ( ) const

pure virtual

Returns true if the components of this key are accessible and whether it can be serialized into an output format.

Private keys from a smart card device will often not be exportable.

◆ convertToPublic()

virtual void QCA::PKeyBase::convertToPublic ( )

pure virtual

If the key is a private key, this function will convert it into a public key (all private key data includes the public data as well, which is why this is possible).

If the key is already a public key, then this function has no effect.

◆ decrypt()

virtual bool QCA::PKeyBase::decrypt	(	const SecureArray &	in,
		SecureArray *	out,
		EncryptionAlgorithm	alg )

virtual

Decrypt data.

Parameters

in	the input data to decrypt
out	pointer to an array to store the plaintext result
alg	the encryption algorithm used to generate the input data

◆ deriveKey()

virtual SymmetricKey QCA::PKeyBase::deriveKey ( const PKeyBase & theirs )

virtual

Compute a symmetric key based on this private key and some other public key.

Essentially for Diffie-Hellman only.

Parameters

theirs the other side (public key) to be used for key generation.

◆ encrypt()

virtual SecureArray QCA::PKeyBase::encrypt	(	const SecureArray &	in,
		EncryptionAlgorithm	alg )

virtual

Encrypt data.

Parameters

in	the input data to encrypt
alg	the encryption algorithm to use

◆ endSign()

virtual QByteArray QCA::PKeyBase::endSign ( )

virtual

Complete a signing operation, and return the signature value.

If there is an error signing, an empty array is returned.

◆ endVerify()

virtual bool QCA::PKeyBase::endVerify ( const QByteArray & sig )

virtual

Complete a verify operation, and return true if successful.

If there is an error verifying, this function returns false.

Parameters

sig	the signature to verify with the input data

◆ finished

void QCA::PKeyBase::finished ( )

signal

Emitted when an asynchronous operation completes on this key.

Such operations will be documented that they emit this signal.

◆ isNull()

virtual bool QCA::PKeyBase::isNull ( ) const

pure virtual

Returns true if this object is not valid.

This is the default state, and the object may also become this state if a conversion or generation function fails.

◆ isPrivate()

virtual bool QCA::PKeyBase::isPrivate ( ) const

pure virtual

Returns true if this is a private key, otherwise false.

◆ maximumEncryptSize()

virtual int QCA::PKeyBase::maximumEncryptSize ( EncryptionAlgorithm alg ) const

virtual

Returns the maximum number of bytes that can be encrypted by this key.

Parameters

alg	the algorithm to be used for encryption

◆ startSign()

virtual void QCA::PKeyBase::startSign	(	SignatureAlgorithm	alg,
		SignatureFormat	format )

virtual

Begin a signing operation.

Parameters

alg	the signature algorithm to use
format	the signature format to use

◆ startVerify()

virtual void QCA::PKeyBase::startVerify	(	SignatureAlgorithm	alg,
		SignatureFormat	format )

virtual

Begin a verify operation.

Parameters

alg	the signature algorithm used by the input signature
format	the signature format used by the input signature

◆ type()

virtual PKey::Type QCA::PKeyBase::type ( ) const

pure virtual

Returns the type of public key.

◆ update()

virtual void QCA::PKeyBase::update ( const MemoryRegion & in )

virtual

Process the plaintext input data for either signing or verifying, whichever operation is active.

Parameters

in	the input data to process
