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.
