Inheritance

Direct Base Classes: Poco::RefCountedObject

All Base Classes: Poco::RefCountedObject

Member Summary

Member Functions: blockSize, cipher, getIV, getKey, ivSize, keySize, mode, name, setIV, setKey

Inherited Functions: duplicate, referenceCount, release

Types

ByteVec

typedef std::vector < unsigned char > ByteVec;

Ptr

typedef Poco::AutoPtr < CipherKeyImpl > Ptr;

Enumerations

Mode

Cipher mode of operation. This mode determines how multiple blocks are connected; this is essential to improve security.

MODE_STREAM_CIPHER

Stream cipher

MODE_ECB

Electronic codebook (plain concatenation)

MODE_CBC

Cipher block chaining (default)

MODE_CFB

Cipher feedback

MODE_OFB

Output feedback

MODE_CTR

Counter mode

MODE_GCM

Galois/Counter mode

MODE_CCM

Counter with CBC-MAC

Constructors

CipherKeyImpl

CipherKeyImpl(
    const std::string & name
);

Creates a new CipherKeyImpl object. Autoinitializes key and initialization vector.

CipherKeyImpl

CipherKeyImpl(
    const std::string & name,
    const ByteVec & key,
    const ByteVec & iv
);

Creates a new CipherKeyImpl object, using the given cipher name, key and initialization vector.

CipherKeyImpl

CipherKeyImpl(
    const std::string & name,
    const std::string & passphrase,
    const std::string & salt,
    int iterationCount,
    const std::string & digest
);

Creates a new CipherKeyImpl object, using the given cipher name, passphrase, salt value and iteration count.

Destructor

~CipherKeyImpl virtual

virtual ~CipherKeyImpl();

Destroys the CipherKeyImpl.

Member Functions

blockSize

int blockSize() const;

setKey inline

void setKey(
    const ByteVec & key
);
