I went with your other suggestion instead: void *input and void *output.
This keeps the code simple and avoids having to do:

if (encap) {
  in = info->key;
  in_len = info->key_len;
  out = info->blob_len;
  out_len = info->key_len + CAAM_BLOB_OVERHEAD; 
} else {
  in = info->blob;
  in_len = info->blob_len;
  out = info->key_len;
  out_len = info->blob_len - CAAM_BLOB_OVERHEAD; 
}
