COBOL
Business-oriented programming language still common in core finance systems—not a cryptosystem; quantum risk sits in surrounding PKI and channels.
Definition
COBOL implements large volumes of transactional and batch business logic in banks and governments. Longevity reflects investment in tested logic, not cryptographic modernity.
Quantum planning should inventory TLS, certificates, HSMs, and partner links the applications use—not treat the language itself as breakable by Shor.
