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.
