There are many JWT libraries, but many of them are hard to use (unclear or fixed API), not optimal (unneeded allocations + strange API). This library addresses all these issues. It's simple to read, to use, memory and CPU conservative. Features
Simple API. Clean and tested code. Optimized for speed. Concurrent-safe. Dependency-free. All well-known algorithms are supported HMAC (HS) RSA (RS) RSA-PSS (PS) ECDSA (ES) EdDSA (EdDSA) or your own!
Health score breakdown
