SYNOPSIS

#include <shishi.h>

Shishi_crypto * shishi_crypto(Shishi * handle, Shishi_key * key, int keyusage, int32_t etype, const char * iv, size_t ivlen);

DESCRIPTION

Initialize a crypto context. This store a key, keyusage, encryption type and initialization vector in a "context", and the caller can then use this context to perform encryption via shishi_crypto_encrypt() and decryption via shishi_crypto_encrypt() without supplying all those details again. The functions also takes care of propagating the IV between calls.
