Member Function Documentation

template<class T>

void DL_EncryptorBase< T >::Encrypt	(	RandomNumberGenerator &	rng,
		const byte *	plaintext,
		size_t	plaintextLength,
		byte *	ciphertext,
		const NameValuePairs &	parameters = `g_nullNameValuePairs`
	)		const

inlinevirtual

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	a set of NameValuePairs to initialize this object

Precondition: CiphertextLength(plaintextLength) != 0 ensures the plaintext isn't too large; COUNTOF(ciphertext) == CiphertextLength(plaintextLength) ensures the output byte buffer is large enough.

See also: PK_Decryptor

Implements PK_Encryptor.
