Real fucking shellcode encryptor & obfuscator tool

🛡 Make safest code in Android. (基于libsodium实现chacha20算法,key在native中,防止被二次打包){长期维护,请star,勿fork}

Ruby FFI binding to the Networking and Cryptography (NaCl) library (a.k.a. libsodium)

Encrypted personal archives

Audited & minimal JS implementation of Salsa20, ChaCha and AES

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。
