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

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.

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
