Decryption
Short answer: Decryption converts ciphertext back into readable plaintext using a key. Learn where it happens and whether quantum computers could decrypt your data.
Definition
Decryption is the process of converting ciphertext back into readable plaintext using a cryptographic key. In symmetric encryption, the same key encrypts and decrypts; in asymmetric encryption, the private key decrypts what the public key encrypted.
Technical Explanation
Decryption reverses encryption by applying inverse operations with the key. For AES, this involves inverse SubBytes, ShiftRows, MixColumns, and AddRoundKey operations. For public-key systems, mathematical trapdoors allow key holders to efficiently reverse encryption that's hard to break otherwise.
Post-quantum decryption must resist quantum attacks. Kyber decapsulation recovers shared secrets that quantum computers cannot derive from ciphertexts. The computational asymmetry remains: decrypting with the key is easy; breaking without it stays hard even for quantum adversaries.
SynX Relevance
SynX decryption operations use Kyber-768 for key decapsulation and AES-256 for symmetric decryption. When your wallet receives encrypted data, it securely decrypts using your private keysโkeys that remain quantum-resistant and locally stored.
Frequently Asked Questions
- Who can decrypt my SynX messages?
- Only you with your private key. The encryption is end-to-end.
- Could quantum computers decrypt my data?
- Not with Kyber-768โit's specifically designed to resist quantum attacks.
- Where does decryption happen?
- Locally on your device. Encrypted data travels; decryption happens on your machine.
