Crate tana_auth 

Tana Authentication Library

JWT creation and validation using Ed25519 signatures. Supports both native Rust and WebAssembly compilation.

Key Features

• User-signed JWTs (not server-signed)
• Ed25519 signature verification
• Compatible with existing Tana key format (ed25519_ prefix)
• WASM support for TypeScript/Bun usage

Usage

use tana_auth::{create_jwt, verify_jwt};

// Create JWT signed by user's private key
let jwt = create_jwt(
    "ed25519_abc123...",  // private key
    "@alice",              // username
    90                     // days until expiration
).unwrap();

// Verify JWT against user's public key
let claims = verify_jwt(&jwt, "ed25519_def456...").unwrap();
