Detailed Description

Cipher provider.

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

QCA::CipherContext::CipherContext	(	Provider *	p,
		const QString &	type
	)			`[inline]`

Standard constructor.

Parameters:

	p	the provider associated with this context
	type	the name of the type of cipher provided by this context

Note:: type includes the name of the cipher (e.g. "aes256"), the operating mode (e.g. "cbc" or "ofb") and the padding type (e.g. "pkcs7") if any.

virtual int QCA::CipherContext::blockSize ( ) const [pure virtual]

Returns the block size for this cipher.

virtual bool QCA::CipherContext::final ( SecureArray * out ) [pure virtual]

Finish the cipher processing.

Returns true if successful.

Parameters:

out

pointer to an array that should store the result

virtual KeyLength QCA::CipherContext::keyLength ( ) const [pure virtual]

Returns the KeyLength for this cipher.

virtual void QCA::CipherContext::setup	(	Direction	dir,
		const SymmetricKey &	key,
		const InitializationVector &	iv
	)			`[pure virtual]`

Set up the object for encrypt/decrypt.

Parameters:

	dir	the direction for the cipher (encryption/decryption)
	key	the symmetric key to use for the cipher
	iv	the initialization vector to use for the cipher (not used in ECB mode)

virtual bool QCA::CipherContext::update	(	const SecureArray &	in,
		SecureArray *	out
	)			`[pure virtual]`

Process a chunk of data.

Returns true if successful.

Parameters:

	in	the input data to process
	out	pointer to an array that should store the result
