Member Function Documentation

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

Encrypt a byte string.

Parameters
rnga RandomNumberGenerator derived class
plaintextthe plaintext byte buffer
plaintextLengththe size of the plaintext byte buffer
ciphertexta byte buffer to hold the encrypted string
parametersadditional 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.

Implements PK_Encryptor.

BufferedTransformation * PK_Encryptor::CreateEncryptionFilter ( RandomNumberGenerator rng,
BufferedTransformation attachment = NULL,
const NameValuePairs parameters = g_nullNameValuePairs 
) const
virtualinherited

Create a new encryption filter.

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

virtual size_t PK_CryptoSystem::FixedCiphertextLength ( ) const
inlinevirtualinherited

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 2150 of file cryptlib.h.

virtual Clonable* Clonable::Clone ( ) const
inlinevirtualinherited

Copies this object.

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