----------------------------------------

This is a set of simple routines that encrypt some data using a
|
|
passphrase. There are defined in the header `cryptobox.h`, inside
|
|
namespace `Botan::CryptoBox`.
|
|
|
|
It generates cipher and MAC keys using 8192 iterations of PBKDF2 with
|
|
HMAC(SHA-512), then encrypts using Serpent in CTR mode and authenticates using a
|
|
HMAC(SHA-512) mac of the ciphertext, truncated to 160 bits.

.. cpp:function:: std::string encrypt(const uint8_t input[], size_t input_len, \
|
|
const std::string& passphrase, \
|
|
RandomNumberGenerator& rng)
|
|
|
|
Encrypt the contents using *passphrase*.

.. cpp:function:: std::string decrypt(const uint8_t input[], size_t input_len, \
|
|
const std::string& passphrase)
|
|
|

Decrypts something encrypted with encrypt.
