shishi_crypto3
Api function
Usage
#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_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. |
Overview
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.
