PGP 密钥服务器具有通过 HTTPS 下载的功能？

Question

我公司的防火墙阻止了端口 80 上的密钥服务器，我希望支持的一些发行版还不具备 HKPS 功能以通过 TLS 获取。

是否有提供通过 HTTPS 简单下载给定密钥的密钥服务器？例如，我可以在https://keybase.io/naftulikay/pgp_keys.asc上获取我自己的个人密钥，该密钥位于密钥库中

是否有资源可以在不使用密钥服务器协议的情况下通过 HTTPS 获取密钥？我正在编写 Ansible，因此通过 HTTPS 获取内容很容易。

openpgp.org有https的设施。只是通过他们的指纹导入了几个密钥。路径是可预测的，您只需要用${KEY_FINGERPRINT}要导入的密钥的指纹替换即可。当然必须已经上传到https://keys.openpgp.org：

curl --sSL https://keys.openpgp.org/vks/v1/by-fingerprint/${KEY_FINGERPRINT} | \
  gpg --import

Ubuntu 密钥服务器还有一个 HTTP(S) API，通过它可以获取 ASCII 格式的密钥：

curl -sSL https://keyserver.ubuntu.com/pks/lookup?op=get&search=0x${KEY_FINGERPRINT} | \
  gpg --import

注意| gpg --import管道，它用于将密钥数据导入 GnuPG 密钥环。

通过 HTTPS 自动导入 GPG/PGP 密钥：

由于路径https://keys.openpgp.org是可预测的，并且仅因存储在服务器上的密钥指纹而异，因此我们可以自动导入由指纹识别的密钥列表。下面经过测试并知道可以正常工作

要使脚本适合您自己的使用，只需将我的 (3) 个样本密钥指纹替换为您要导入的密钥指纹，当然还可以将变量设置PATHSCRIPTS为您想要的路径：

#!/bin/bash

PATHSCRIPTS='/home/pi'

# Create text file using a Here-Doc containing Key Fingerprints of keys to import into keyring:

cat <<EOF> $PATHSCRIPTS/Key-fingerprints-list.txt
AEB042FFD73BAA7545EDA021343A2DF613C5E7F8
7AFAF20259E69236E43EEF521F45D0F6E89F27A6
704FCD2556C40AF8F2FBD8E2E5A1DE67F98FA66F
EOF

# Read the text file we created into an array
readarray arrayKeyFingerprints < $PATHSCRIPTS/Key-fingerprints-list.txt

# Loop through the array adding each key in turn by its fingerprint from keys.openpgp.org:
for i in ${arrayKeyFingerprints[@]}; do
    curl https://keys.openpgp.org/vks/v1/by-fingerprint/$i | gpg --import
done

上述脚本的结果 - 保存为test.sh并在 Raspberry Pi 上运行 - 如下所示：

我们做了一个密钥列表，有我们的 (3) 个导入的密钥：

pi@pi4-ap1:~ $ gpg --list-keys
