Rust/Tokio
SDK built using 100% safe rust for maximum security and performance
Powered using the Tokio asynchronous runtime
Extreme Security
Post-quantum key exchange, multi-layered ratcheting, per-message adjustable multi-layered cryptography, and many other adjustable options
P2P
Includes built-in NAT traversal for enabling the use of peer to peer applications
File Transfer Scrambling
All files transferred between client/server or peer-to-peer are scrambled with an independent key for higher security
Perfect Forward Secrecy + Best Effort Mode
Each session can be configured to enforce perfect forward secrecy for maximum security, or, best-effort mode for maximum throughput
Hybrid Cryptography
Each session by default uses TLS or QUIC as a base layer coupled with the post-quantum Lusna Protocol for quantum resistance
Argon2id Password Hashing
A built-in parameter autotuner and authenticator allows creating secure authenticated sessions seemlessly
Passwordless Authentication
Configure sessions to use passwordless authentication for connections
Credentialed Authentication
Configure sessions to use credentials for added security
SDK in Action
Citadel SDK
Use the Citadel SDK to rapidly create decentralized or traditional client/server network applications using the latest advancements in network security
Client Code (Authenticated User)
Fast
The Citadel SDK uses the rust programming language to leverage speed and efficiency.
The file-transfer API makes use of asynchronous multithreading to boast speeds up to 50% faster than SCP
Single/Multi-Threaded Modes
Easily change between single and multi-threaded protocol event loops at compile-time to fine-tune to the requirements of your application
Scalable Backends
Configure your application to use a MySQL, PostgreSQL, SQLite, or Redis backends to scale your application across a network
