4 KB 左右的 ChaCha20Poly1305 认证加密算法实现，参考 https://github.com/thesimj/js-chacha20 和 https://github.com/devi/chacha20poly1305 进行了少量修改。
const { ChaCha20Poly1305 } = require('./chacha20poly1305.min.js');
const hexToBytes = e => new Uint8Array(e.match(/[0-9a-f]{2}/gi).map(e => parseInt(e, 16)));
const bytesToHex = e => Array.from(e).map(e => e.toString(16).padStart(2, 0)).join('');
// Test vectors from:

10 KB 左右的 Ed25519 签名和验证算法实现，在 https://github.com/paulmillr/noble-ed25519 的基础上添加了 IIFE，将使用的 SHA-512 从 Web Crypto API 替换成 https://github.com/emn178/js-sha512 从而实现同步调用，并进行了部分修改以减小 minify 后的大小。
const Ed25519 = require('./ed25519.min.js');
const hexToBytes = e => new Uint8Array(e.match(/[0-9a-f]{2}/gi).map(e => parseInt(e, 16)));
const bytesToHex = e => Array.from(e).map(e => e.toString(16).padStart(2, 0)).join('');
