Api function
#include <shishi.h>
Shishi_crypto * shishi_crypto(Shishi * handle, Shishi_key * key, int keyusage, int32_t etype, const char * iv, size_t ivlen);
shishi handle as allocated by shishi_init().
key to encrypt with.
integer specifying what this key will encrypt/decrypt.
integer specifying what cipher to use.
input array with initialization vector
size of input array with initialization vector.
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.
When the application no longer need to use the context, it should deallocate resources associated with it by calling shishi_crypto_close().
Return a newly allocated crypto context.
