How we test

Calculators are checked against results worked out by hand, and crypto tools (JWT, AES, PASETO, password hashing) against an independent implementation, before every release.

Be careful with

• Real passwords, API keys and production tokens
• Legally binding contracts and official financial documents
• Tax, payroll and loan figures that must be exact
• Encryption and password hashing for production systems
