Member Function Documentation

std::string AlgorithmImpl< DL_EncryptorBase< SCHEME_OPTIONS::Element > , SCHEME_OPTIONS::AlgorithmInfo >::AlgorithmName (  )  const [inline, virtual, inherited]

Reimplemented from Algorithm.

Definition at line 42 of file simple.h.

void DL_EncryptorBase< SCHEME_OPTIONS::Element >::Encrypt ( RandomNumberGenerator rng,
const byte *  plaintext,
size_t  plaintextLength,
byte *  ciphertext,
const NameValuePairs parameters = g_nullNameValuePairs 
) const [inline, virtual, inherited]

Encrypt a byte string.

Parameters:
rng a RandomNumberGenerator derived class
plaintext the plaintext byte buffer
plaintextLength the size of the plaintext byte buffer
ciphertext a byte buffer to hold the encrypted string
parameters additional configuration options
Precondition:
CiphertextLength(plaintextLength) != 0 ensures the plaintext isn't too large
COUNTOF(ciphertext) == CiphertextLength(plaintextLength) ensures the output byte buffer is large enough.

PK_Decryptor

Implements PK_Encryptor.

size_t DL_CryptoSystemBase< PK_Encryptor , DL_PublicKey< SCHEME_OPTIONS::Element > >::MaxPlaintextLength ( size_t  ciphertextLength  )  const [inline, virtual, inherited]

Implements PK_CryptoSystem.

Definition at line 1408 of file pubkey.h.

size_t DL_CryptoSystemBase< PK_Encryptor , DL_PublicKey< SCHEME_OPTIONS::Element > >::CiphertextLength ( size_t  plaintextLength  )  const [inline, virtual, inherited]

Implements PK_CryptoSystem.

Definition at line 1414 of file pubkey.h.

bool DL_CryptoSystemBase< PK_Encryptor , DL_PublicKey< SCHEME_OPTIONS::Element > >::ParameterSupported ( const char *  name  )  const [inline, virtual, inherited]

Implements PK_CryptoSystem.

Definition at line 1420 of file pubkey.h.

BufferedTransformation * PK_Encryptor::CreateEncryptionFilter ( RandomNumberGenerator rng,
BufferedTransformation attachment = NULL,
const NameValuePairs parameters = g_nullNameValuePairs 
) const [virtual, inherited]

Create a new encryption filter.

Note:
The caller is responsible for deleting the returned pointer.
Encoding parameters should be passed in the "EP" channel.

Definition at line 816 of file cryptlib.cpp.

virtual size_t PK_CryptoSystem::FixedCiphertextLength (  )  const [inline, virtual, inherited]

return fixed ciphertext length, if one exists, otherwise return 0

Note:
"Fixed" here means length of ciphertext does not depend on length of plaintext. It usually does depend on the key length.

Definition at line 2151 of file cryptlib.h.

virtual Clonable* Clonable::Clone (  )  const [inline, virtual, inherited]

Copies this object.

Returns:
a copy of this object
Exceptions:
NotImplemented 
Note:
this is not implemented by most classes
