How to Use This Calculator
- Enter the algorithm type (symmetric, asymmetric, hash) and key or parameter size.
- Set the compliance framework: NIST, FIPS 140-3, or CNSA Suite.
- Review the security strength rating in bits.
- Flag any algorithm below 112-bit security for immediate deprecation planning.
- Use the output to compile a cryptographic inventory for compliance audits.
