What is Post-Quantum Cryptography (PQC) Software for Mac?

Post-quantum cryptography (PQC) software refers to cryptographic systems and algorithms designed to secure data against the potential future threat posed by quantum computers. Traditional cryptographic methods, such as RSA and ECC (Elliptic Curve Cryptography), rely on the difficulty of certain mathematical problems that could be solved efficiently by a sufficiently powerful quantum computer. Post-quantum cryptography focuses on developing new cryptographic protocols that are resistant to quantum computing threats, utilizing algorithms based on lattice-based, hash-based, multivariate, or code-based cryptography. This software ensures that data remains secure even in the era of quantum computing, offering a bridge between today's cryptographic practices and the future landscape of quantum-enhanced threats.
