Quantum Computing: Breaking the RSA Encryption Barrier
The Quantum Threat
Quantum computers leverage the principles of quantum mechanics to process information in ways classical computers cannot. The most significant threat they pose is to current cryptographic algorithms, specifically RSA.
Using Shor's algorithm, a sufficiently powerful quantum computer could factor large integers efficiently, completely dismantling the security of RSA encryption which relies on this complexity.

Post-Quantum Cryptography
The transition to post-quantum cryptography (PQC) is no longer a theoretical exercise but an urgent engineering requirement. Organizations must evaluate their cryptographic agility today.
