Cryptobox
========================================
Encryption using a passphrase
----------------------------------------
.. versionadded:: 1.8.6
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.
.. cpp:function:: std::string decrypt(const std::string& input, \
const std::string& passphrase)
Decrypts something encrypted with encrypt.
