-大多数公开讨论的 OpenPGP 安全问题
-实际上都源于工具或应用的糟糕可用性或糟糕实现（或两者兼而有之）。
-区分 OpenPGP（IETF 加密标准）
-和 GnuPG (GPG)（实现 OpenPGP 的命令行工具）尤为重要。
-许多对 OpenPGP 的公开批评实际上是在讨论 GnuPG，而 Delta Chat 从未使用过 GnuPG。
-Delta Chat 而是使用 OpenPGP Rust 实现 <a href="https://github.com/rpgp/rpgp">rPGP</a>，
-作为 <a href="https://crates.io/crates/pgp">独立的“pgp”软件包</a> 提供，
-并且 <a href="https://delta.chat/assets/blog/2019-first-security-review.pdf">在 2019 年进行了安全审计</a>。</p>
+<p>OpenPGP is not insecure by itself.
+Most publically discussed OpenPGP security problems
+actually stem from bad usability or bad implementations of tools or apps (or both).
+It is particularly important to distinguish between OpenPGP, the IETF encryption standard, 
+and GnuPG (GPG), a command line tool implementing OpenPGP. 
+Many public critiques of OpenPGP actually discuss GnuPG which Delta Chat has never used. 
+Delta Chat rather uses the OpenPGP Rust implementation <a href="https://github.com/rpgp/rpgp">rPGP</a>,
+available as <a href="https://crates.io/crates/pgp">an independent “pgp” package</a>,
+and <a href="#security-audits">security-audited in 2019 and 2024</a>.</p>
 
 <p>我们的目标是与其他 OpenPGP 实现者一起，
 通过实施 <a href="https://datatracker.ietf.org/doc/draft-ietf-openpgp-crypto-refresh/">新的 IETF OpenPGP Crypto-Refresh</a>
