What is post-quantum cryptography?

Post-quantum crypto uses math problems — like lattices or hashes — that quantum machines struggle with, unlike factoring primes in RSA.

When will quantum computers break bank encryption?

Optimists say 2030s with million-qubit machines; realists point to NIST's 2033 deadline as the panic trigger.

How can fintechs prepare for quantum threats?

Start with hybrid keys in TLS 1.3, audit vendors for NIST PQC support, and budget 2x for key management upgrades.
