Symmetric Encryption
Symmetric encryption uses the same key for encryption and decryption. It is extremely fast but requires a secure way to share the key. AES-256 is the most common symmetric algorithm used in messaging.
Privacy Guide
Symmetric vs Asymmetric Encryption Explained
Symmetric encryption uses one shared key while asymmetric uses a key pair. Modern secure messaging combines both methods for optimal speed and security.

Asymmetric Encryption
Asymmetric encryption uses a public key to encrypt and a private key to decrypt. It solves the key distribution problem but is computationally slower than symmetric methods.
Hybrid Approach in Messaging
Modern messengers like WeTalkin use asymmetric encryption to exchange symmetric session keys. The actual message content is then encrypted with fast symmetric algorithms. This combines the security of asymmetric with the speed of symmetric.
Which Is More Secure?
Neither is inherently more secure—they serve different purposes. The hybrid approach used by WeTalkin provides the strongest protection by leveraging the best properties of each method.

Frequently Asked Questions
Does WeTalkin use symmetric or asymmetric encryption?
WeTalkin uses both in a hybrid system. Asymmetric encryption establishes secure connections, then symmetric encryption handles fast message encryption.
Is AES-256 unbreakable?
AES-256 is considered computationally infeasible to break with current or foreseeable technology. It would take billions of years for the fastest computers to crack.
Why not use asymmetric encryption for everything?
Asymmetric encryption is roughly 1000x slower than symmetric. The hybrid approach gives you both strong key exchange and fast message processing.
