Quantum-Resistant Cryptography
Security
Jan 10, 2025
As quantum computing advances, traditional cryptographic algorithms face unprecedented threats. In this post, we'll explore how quantum-resistant cryptography can future-proof our systems and the practical steps we've taken here at Egea to implement these solutions.
Why Traditional Crypto is Vulnerable
Algorithms like RSA and ECC rely on mathematical problems that quantum computers can solve exponentially faster using algorithms like Shor's algorithm.
Shor's algorithm breaks down large numbers in O(log³ N) time, devastating RSA security
Pro Tip: Start auditing your crypto usage today! Check for any RSA, ECC, or SHA-1 usage patterns in your codebase.
