Performing Cipher Encryption and Decryption Based on the Context

For details, see Performing Cipher Encryption and Decryption Based on the Context. This section only adds the tag input parameter for invoking the callback function in the poll thread after the task is complete.

struct cipher_async_tag {
  void *ctx;
void *pool;
int thread_id;
int cnt;
} *tag;
tag = malloc(sizeof(*tag));
tag->ctx = ctx;
tag->thread_id = thread_id;
tag->cnt = 0;
tag->pool = pool;
wd_do_cipher(ctx, &opdata, tag);
