## プロジェクトの歴史と使われ方

Botan is a permissively licensed C++ cryptography toolkit with a library-first identity and a substantial command-line companion. In package-manager culture it occupies the same broad territory as OpenSSL, libsodium, and Crypto++, but with a C++ API, modular build controls, Python/C FFI surfaces, and an intentionally broad algorithm catalog.

### プロジェクトの歴史

The current public development home is the randombit/botan GitHub repository, created in March 2013, while the official documentation describes Botan as a C++ cryptography library focused on production cryptography. Its handbook frames the project around secure distributed systems, constant-time programming, test coverage, side-channel analysis, safe defaults, portability to modern systems, and post-quantum readiness.

Botan 3 became the active release line, with the upstream README documenting quarterly Botan3 minor releases. Botan2 reached end of life on 2025-01-01, with the final Botan2 release listed as 2.19.5 from 2024-07-08.

### 採用の歴史

Botan is distributed by major Unix-like package systems, including Homebrew, Debian-family distributions, Fedora, Arch, MacPorts, and openSUSE according to the package facts and the upstream README's distribution note. Its adoption is less about a single dominant CLI and more about being a reusable cryptographic substrate for C++ applications that want TLS, X.509, PKCS#11, TPM, password hashing, and newer post-quantum primitives without binding themselves to OpenSSL APIs.

The project also exposes C, Python, and third-party language bindings, which makes it useful to packagers who want one audited native cryptography implementation to serve multiple language ecosystems.

### 使われ方

The installed `botan` executable exposes many library functions in shell form: hashing, HMAC, password hashing, symmetric encryption, public-key operations, certificate handling, TLS-related tooling, and other cryptographic utilities. The library side is used by applications that need a C++ cryptography API with configurable modules and platform certificate-store support.

For package users, Botan is commonly installed as a development dependency as well as a CLI utility; its package significance comes from headers, libraries, ABI concerns, and feature selection as much as from the command-line binary.

### パッケージ好きにとっての重要性

Botan is a classic package-nerd library: it is security-sensitive, ABI-sensitive, heavily tested, and exposed through many downstream packages. Its release notes read like infrastructure maintenance, with CVEs, certificate-path behavior, compiler support, optimized CPU code paths, TLS conformance, and algorithm additions all mattering to downstream maintainers.

It is also notable as a modern C++ crypto stack that deliberately includes post-quantum algorithms and side-channel testing in its project goals, making it a useful barometer for where general-purpose cryptography libraries are moving.

### タイムライン

- 2013: Public GitHub repository created for randombit/botan.
- 2024: Botan 2.19.5 released as the final Botan2 series release.
- 2025: Botan2 reached end of life on January 1.
- 2026: Botan 3.12.0 released with TLS, X.509, performance, and security fixes.

### Related projects

- OpenSSL is the most common comparison point for everyday command-line crypto and TLS tooling.
- Crypto++ is a related C++ cryptography library in the same packaging space.
- libsodium is a related security library with a narrower, opinionated API surface.
