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.

Constructor & Destructor Documentation

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.


Member Function Documentation

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
