Ciphertext
Definition
Ciphertext is data that has been transformed through encryption into an unreadable format. Only parties possessing the correct decryption key can recover the original plaintext from ciphertext. Well-designed ciphertext reveals nothing about the underlying message to unauthorized observers.
Technical Explanation
Modern encryption algorithms produce ciphertext indistinguishable from random data (semantic security). Each encryption with the same key produces different ciphertext due to random initialization vectors, preventing pattern analysis. Ciphertext length typically relates to plaintext length but reveals no content information.
The threat of quantum computers motivates post-quantum encryption. Ciphertext encrypted with classical algorithms like RSA could be stored and later decrypted by quantum computers. Ciphertext protected by quantum-resistant algorithms like Kyber remains secure indefinitely, even against future quantum attacks.
SynX Relevance
All sensitive SynX communications produce quantum-resistant ciphertext. Whether it's wallet-to-daemon messages or encrypted transaction data, adversaries capturing this ciphertext cannot decrypt it—not today with classical computers, and not tomorrow with quantum computers.
Frequently Asked Questions
- Can anyone decrypt my SynX ciphertext?
- Only you with your private keys. The ciphertext is quantum-resistant.
- Does storing ciphertext pose a risk?
- With quantum-resistant encryption, no. Stored ciphertext remains secure forever.
- Is SynX ciphertext larger than classical encryption?
- Kyber ciphertexts are slightly larger but still practical for all use cases.
