# opencl_vanity_gpg 使用 GPU（OpenCL）快速生成带有“靓号”的 PGP 密钥！ “靓号”指的是带有连号等特定格式的密钥指纹或 ID（例如以 `77777777` 结尾），具体介绍和生成原理请参见： * [一位 PGP 进步青年的科学算号实践](https://www.douban.com/note/763978955/) * [某科学的 PGP 算号指南](https://blog.dejavu.moe/posts/the-scientific-vanity-pgp-counting-guide/) ![](https://github.com/user-attachments/assets/e6364d93-fffe-4fcd-9857-b70155e6f476) 简单来说，密钥指纹是密钥生效时间和公钥内容的 SHA-1，通过不断生成密钥和修改时间（成本更低）的暴力遍历方式找到“靓号”。 > [!TIP] > > 姊妹项目：使用 WebGL 实现的网页版 [TransparentLC/webgl-vanity-gpg](https://github.com/TransparentLC/webgl-vanity-gpg) > > 实际上这个项目也可以当成是它的“锈化”版…\_φ(･ω･` ) 目前最好的同类工具是使用 CPU 的 [RedL0tus/VanityGPG](https://github.com/RedL0tus/VanityGPG) 和使用 GPU（CUDA）的 [cuihaoleo/gpg-fingerprint-filter-gpu](https://github.com/cuihaoleo/gpg-fingerprint-filter-gpu)。这个项目是使用 GPU（OpenCL）实现的，优点当然是开箱即用了。 > TODO: GitHub Actions 自动编译 # 使用方法 ```console $ opencl_vanity_gpg -h Usage: opencl_vanity_gpg [OPTIONS] Options: -c, --cipher-suite Cipher suite of the vanity key ed25519, ecdsa-****, rsa**** => Primary key cv25519, ecdh-**** => Subkey Use gpg CLI for further editing of the key.
