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
• 某科学的 PGP 算号指南

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

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 和使用 GPU（CUDA）的 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。

GitHub Actions 有自动编译好的二进制文件。

使用方法

$ opencl_vanity_gpg -h
Usage: opencl_vanity_gpg [OPTIONS]

Options:
  -c, --cipher-suite <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. [default: ed25519] [possible values: ed25519, cv25519, rsa2048, rsa3072, rsa4096, ecdh-p256, ecdh-p384, ecdh-p521, ecdsa-p256, ecdsa-p384, ecdsa-p521]
  -u, --user-id <USER_ID>            OpenPGP compatible user ID [default: "Dummy <dummy@example.com>"]
  -p, --pattern <PATTERN>            A pattern less than 40 chars for matching fingerprints
                                     Format:
                                     * 0-9A-F are fixed, G-Z are wildcards
                                     * Other chars will be ignored
                                     * Case insensitive
                                     Example:
                                     * 11XXXX** may output a fingerprint ends with 11222234 or 11AAAABF
                                     * 11XXYYZZ may output a fingerprint ends with 11223344 or 11AABBCC
  -f, --filter <FILTER>              OpenCL kernel function for uint h[5] for matching fingerprints
                                     Ignore the pattern and no estimate is given if this has been set
                                     Example:
                                     * (h[4] & 0xFFFF)     == 0x1234     outputs a fingerprint ends with 1234
                                     * (h[0] & 0xFFFF0000) == 0xABCD0000 outputs a fingerprint starts with ABCD
  -o, --output <OUTPUT>              The dir where the vanity keys are saved
  -d, --device <DEVICE>              Device ID to use
  -t, --thread <THREAD>              Adjust it to maximum your device's usage
  -i, --iteration <ITERATION>        Adjust it to maximum your device's usage [default: 512]
      --timeout <TIMEOUT>            Exit after a specified time in seconds
      --oneshot                      Exit after getting a vanity key
      --no-progress                  Don't print progress
      --no-secret-key-logging        Don't print armored secret key
      --device-list                  Show available OpenCL devices then exit
  -h, --help                         Print help
  -V, --version                      Print version

一个 Curve25519 的密钥由用来签名和认证的 Ed25519 主密钥和用来加密的 Cv25519 子密钥组成。VanityGPG 只能生成主密钥为“靓号”的密钥，而这个项目也可以生成子密钥为“靓号”的密钥（只需要添加参数 -c cv25519 即可）。对于其他 NISP P-*** 的椭圆曲线的密钥也是类似的。

性能对比

这个项目	CPU	120m	Xeon w5-2465X ×16 cores CPU 也可以是 OpenCL 的计算设备，虽然性能损耗比较严重……
TransparentLC/webgl-vanity-gpg	GPU	2b	GTX 1070
这个项目	GPU	3b	GTX 1070
TransparentLC/webgl-vanity-gpg	GPU	7b	RTX A5500
