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

CipherContext()

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

blockSize()

virtual int QCA::CipherContext::blockSize ( ) const

pure virtual

Returns the block size for this cipher.

final()

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

keyLength()

virtual KeyLength QCA::CipherContext::keyLength ( ) const

pure virtual

Returns the KeyLength for this cipher.

setup()

virtual void QCA::CipherContext::setup ( Direction dir, const SymmetricKey & key, const InitializationVector & iv, const AuthTag & tag )

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)
tag	the AuthTag to use (only for GCM and CCM modes)

tag()

virtual AuthTag QCA::CipherContext::tag ( ) const

pure virtual

Returns the authentication tag for this cipher.

update()

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
