我正在尝试在具有GnuPG扩展名的PHP上检查PGP公钥的签名。
用$gpg->import($key)导入密钥后，我正在运行$gpg->keyinfo('')，这就是结果；
[0] => Array
(
[disabled] =>
[expired] =>
[revoked] =>
[is_secret] =>
[can_sign] => 1
[can_encrypt] => 1
[uids] => Array
(
[0] => Array
(
[name] => test
[comment] =>
[email] => test@test.com
[uid] => test <test@test.com>
[revoked] =>
[invalid] =>
)
)
[subkeys] => Array
(
[0] => Array
(
[fingerprint] => 123456123456123456123456123456123456

[expires] => 0
[is_secret] =>
[invalid] =>
[can_encrypt] =>
[can_sign] => 1

)
)
很遗憾，它没有签名。我也尝试了verifySignature函数，但显示“未找到签名”。如何使用PHP获得公钥的签名？如果我使用exec运行gpg并解析输出，可以吗？
