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;
}
