Encrypted personal archives

Audited & minimal JS implementation of Salsa20, ChaCha and AES

TikTok X-Gnarly, X-Bogus, and X-Dynosaur signature generator for Web API requests. Supports SDK version 5.1.2 (build 1.0.0.316). Python implementation with ChaCha20 and RC4 encryption, dynamic round selection, and custom Base64 encoding. Lightweight, fast, and production-ready.

生成19位的Long ID、22位的短UUID、卡号、短卡号、带校验码卡号、激活码、付款码、数据加密、手机号加密、带失效时间的数字加密。生成器是分布式，支持多负载，无需数据库、redis或者zk作为ID分配的key。ID分配无需RPC调用，基于本地内存计算，结构简单，可靠性和性能比较高。
