Post-quantum cryptography · Software security

Security
that does not expire.

We protect the information your organization needs to keep secret for decades, today and once quantum computing arrives.

post-quantum encryption: ML-KEM-768, long-term confidentiality, code analysis: SAST, cybersecurity advisory

Standards we work with: FIPS 203, ML-KEM-768, AES-256-GCM, OWASP Top 10, OWASP ASVS, CWE, CVSS, SARIF, CycloneDX, SBOM.

01 · Try it

Type something your company cannot afford to leak.

We encrypt it twice: with the cryptography adopted worldwide today, and with Klara's. Then move the clock forward.

Your message travels encrypted. Someone copies it and keeps it.

How many years must it stay secret?

Your information has to stay secret until 2036. Under classical encryption, whatever is intercepted today is exposed before then.

If someone stores your encrypted communications today, all they have to do is wait. Migrating takes years, so it pays to start before the risk is visible.

Let's talk about your case

Illustrative simulation: nothing is encrypted or sent. Reference dates: NIST IR 8547 (draft, 2024) proposes deprecating RSA and elliptic curves from 2030 and disallowing them from 2035.

02 · The problem

Harvest Now, Decrypt Later.

Whatever travels today under classical encryption can be intercepted and stored. Once a quantum computer with enough capacity exists, it can be read.

  1. TODAY

    Encrypted data is intercepted and stored

    Under classical encryption it is still unreadable. For now.

  2. LATER

    A capable quantum computer arrives

    RSA and elliptic curves stop protecting what was stored.

  3. OUTCOME

    What was confidential no longer is

    With no warning and no way to undo it.

Your information has to stay confidential for

10–30

years

That data is already at risk today.

  • Legal files

    Professional secrecy and litigation strategy

  • Medical records

    Health data that lasts a lifetime

  • Financial and government information

    Sensitive operations, contracts and communications

03 · Product

Klara changes the level of security, not the way you work.

Klara

File and message encryption with post-quantum cryptography. It works over the channels you already use, and the decryption key never leaves the device.

  1. Protect

    Pick the file or message and its recipients. It is encrypted on your device.

  2. Share

    Send it by email, messaging, cloud or USB, as you always do.

  3. Open

    Only the recipient can decrypt it, on their own device.

04 · Services

Security with technical judgment.

  • Code analysis (SAST)

    We review your source code and its dependencies, and deliver prioritized findings referenced to OWASP and CWE.

  • Cybersecurity advisory

    We help you understand your exposure, prioritize risks and decide where to invest first.

  • Post-quantum assessment

    We identify which information and systems are exposed to harvest now, decrypt later, and where to start.
