HQC Joins the Crypto Party: NIST’s Latest Backup Plan for a Secure Future
NIST’s cryptographic playlist gets a remix with the addition of HQC, the fifth algorithm in its post-quantum cryptography (PQC) lineup. HQC is the backup dancer to ML-KEM, ready to step in when needed. While HQC is a bit of a resource hog, it promises secure moves with its error-correcting code choreography.

Hot Take:
Who knew post-quantum cryptography could sound like a game of “backup the backup”? NIST is adding a fifth algorithm, HQC, to its portfolio, ensuring that when it comes to quantum-proofing our secrets, we’ve got all the bases covered. It’s like having a spare tire for your spare tire – because who needs a quantum computer to mess with your data when you’ve got HQC on your side?
Key Points:
- NIST adds HQC as a fifth algorithm to its post-quantum cryptography (PQC) portfolio.
- The finalized HQC standard is expected to be available by 2027.
- HQC will serve as a backup for ML-KEM, a key encapsulation mechanism (KEM).
- NIST recommends migrating to existing finalized standards ahead of HQC’s completion.
- HQC’s algorithm is based on error-correcting codes, offering a different mathematical approach.
