NAME
       shishi_crypto - API function


SYNOPSIS
       #include <shishi.h>

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


ARGUMENTS
       Shishi * handle
                   shishi handle as allocated by shishi_init().

       Shishi_key * key
                   key to encrypt with.

       int keyusage
                   integer specifying what this key will encrypt/decrypt.

       int32_t etype
                   integer specifying what cipher to use.

       const char * iv
                   input array with initialization vector

       size_t ivlen
                   size of input array with initialization vector.


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.

       When the application no longer need to use the context, it should deallocate resources associated with it
       by calling shishi_crypto_close().


RETURN VALUE
       Return a newly allocated crypto context.
