## 项目历史与用法

ntbTLS, the Not Too Bad TLS Library, is a small GnuPG-family TLS 1.2 client library intended to pair with Libgcrypt and LibKSBA. It deliberately leaves certificate verification to callers such as GnuPG's `dirmngr`.

### 项目历史

The GnuPG wiki says ntbTLS started in 2014 as Werner Koch's stripped-down fork of PolarSSL, later known as mbedTLS, using Libgcrypt and existing GnuPG modules for X.509 handling. The official page says the code replaced PolarSSL crypto with Libgcrypt, removed older SSL/TLS protocol support, and has been used by the GnuPG version of Gpg4win since 2017.

### 采用历史

ntbTLS is narrow infrastructure rather than a general TLS competitor. The GnuPG libraries page lists it under other GnuPG-related libraries, while the project page frames it as a good fit where GnuPG already has certificate verification and wants to avoid pulling in another TLS library's crypto stack.

The release directory shows public tarballs from 0.1.0 on February 21, 2017 through 0.3.2 on January 12, 2024. On July 1, 2026, Homebrew listed ntbTLS 0.3.2 with 62 installs in its 365-day analytics window, which matches its specialized role.

### 使用方式

Package users usually encounter `ntbtls-config` and the library as build-time plumbing for GnuPG-adjacent software. It is not a drop-in OpenSSL replacement: the README says the server part and TLS 1.3 are not implemented in version 0.3, and callers must do certificate verification themselves.

### 为什么软件包爱好者会关心

ntbTLS matters because it shows the GnuPG project's preference for minimizing independent crypto implementations inside the stack. For packagers, the important details are its Libgcrypt/LibKSBA dependencies, GPL licensing, and intentionally limited protocol surface.

### 时间线

- 2014: ntbTLS began as a stripped-down PolarSSL fork.
- February 21, 2017: the GnuPG file area published ntbtls-0.1.0.
- 2017: Gpg4win's GnuPG build began using ntbTLS.
- January 12, 2024: ntbtls-0.3.2 tarball date in the GnuPG file area.
- July 1, 2026: Homebrew listed stable version 0.3.2.

### Related projects

- Libgcrypt supplies cryptographic primitives.
- LibKSBA supplies X.509 and CMS handling.
- PolarSSL/mbedTLS is the historical source base for the TLS protocol code.
- GnuPG and Gpg4win are the main practical ecosystem.
