 You can use the subkey with signing capability whose fingerprint is `C17D11ADF199F12A30A0910F1F80449BE0B08CB8`.

+### Set key's trust level
+
+With the `trust_level` input, you can specify the trust level of the GPG key.
+
+Valid values are:
+* `1`: unknown
+* `2`: never
+* `3`: marginal
+* `4`: full
+* `5`: ultimate
