Someone can copy encrypted data today and keep it in case future technology lets them decrypt it—a risk known as “harvest now, decrypt later” (HNDL). The concern is especially relevant to information that must stay confidential for years and is protected by quantum-vulnerable public-key cryptography. It does not mean that today’s encryption has already been broken, and no one knows when a quantum computer capable of breaking current public-key cryptography will be available.
How encrypted data could become readable later
An attacker does not necessarily need to decrypt a captured message immediately. They can store ciphertext now and try to read it if their capabilities improve. NIST describes this as the “harvest now, decrypt later” threat. The risk depends on the cryptography involved and how long the information needs to remain secret; it is not a claim that every encrypted file or connection can be decrypted by a future quantum computer. NIST explains the threat and post-quantum cryptography.

The central concern in NIST’s migration guidance is quantum-vulnerable public-key cryptography. That makes long-lived secrets—such as health records, financial data, intellectual property, and national-security information—important to consider. NIST does not give a dependable arrival date for a cryptographically relevant quantum computer: predictions vary, and the timeline is unknown. Some researchers consider a capability possible in less than 10 years, but that is a possibility, not a forecast. NIST’s FAQ discusses the uncertain timeline.
What you can do now
If you manage technology for an organization
- Start with confidentiality lifetime. Identify information whose secrecy must last many years, and determine which systems create, transmit, store, or protect it. Prioritize by sensitivity and the consequences of exposure, not merely by how much data a system holds. NIST names health records, financial data, intellectual property, and national-security information as examples of data to prioritize. NIST’s FAQ gives examples and planning guidance.
- Build a cryptographic inventory. Record where public-key algorithms are used and which assets depend on them. NIST’s guidance includes keys, certificates, protocols, libraries, and hardware security modules, along with the hardware, software, and services that use cryptography. An inventory helps establish what needs attention and where a change could affect other components. NIST’s NCCoE project describes the migration work.
- Assess exposure and migration feasibility. For each important system, consider the data’s sensitivity and required confidentiality lifetime, where public-key cryptography is used, the system’s exposure and impact, and how ready its vendors are to support migration. These factors help determine which changes should come first.
- Make a migration roadmap. Plan how systems will move to post-quantum cryptography (PQC), accounting for dependencies across hardware, software, services, and suppliers. NIST recommends beginning the transition to its standards; the first three finalized PQC standards were released in 2024 and are ready to implement. They are FIPS 203 (ML-KEM), FIPS 204 (ML-DSA), and FIPS 205 (SLH-DSA). NIST’s NCCoE project identifies the standards and migration focus.
- Ask vendors specific questions. Ask whether their products and services use quantum-vulnerable public-key cryptography, what their PQC migration plans are, and when they expect to support the relevant standards. Include suppliers in the roadmap where their technology protects or processes sensitive data. NIST recommends discussing transition plans with technology vendors and suppliers.
NIST notes that integrating new algorithms into information systems has historically taken 10 to 20 years. That figure describes past integration experience; it is not a prediction that this migration will take exactly that long. It is a reason to plan rather than wait for a quantum-computing deadline that no one can reliably set. NIST’s FAQ provides this historical context.

- Certified to FIPS 197 - High-level information security standard approved by the U.S. Government
- Brute-Force Password Attack Protection - Data is automatically erased after 6 failed access attempts. The data and encryption key are securely destroyed and the crypto drive is reset
- Rugged Double-Layer Waterproof* Design - Protects the crypto drive against knocks, drops, break-in and submerging in water. The electronics are shielded by a hardended inner case. The rubberised silicone outer casing provides a final layer of protection
- Auto-lock - The crypto drive will automatically encrypt all data and lock when removed from a PC/Mac or when the screen saver or "computer lock" function is activated on the host PC/Mac
- Secure Entry - Data cannot be accessed without the correct high-strength alphanumeric 8-16 character password. A password hint option is available. The password hint cannot match the password
If you are choosing services or products for personal use
There is no universal consumer setting or physical device identified by NIST’s guidance that makes all existing ciphertext quantum-safe. For information you need to keep private for a long time, look for providers that explain their PQC migration plans and ask how they intend to support the standards. An “encrypted” label by itself does not establish that a service has addressed HNDL; this advice applies NIST’s broader vendor-planning guidance to consumer choices.
What post-quantum standards do—and do not—mean
PQC standards are designed to provide cryptographic methods intended to resist attacks from both conventional and quantum computers. NIST’s first three finalized standards, released in 2024, cover key establishment and digital signatures: FIPS 203 (ML-KEM), FIPS 204 (ML-DSA), and FIPS 205 (SLH-DSA). Their availability gives organizations standards to plan around, but it does not mean that every device, service, or supplier has already adopted them. NIST’s NCCoE project lists the standards and focuses on migration.

Migration is a systems task, not simply a matter of changing one setting. Organizations need to find cryptographic uses, dependencies, and suppliers, then sequence changes without losing track of the systems that protect sensitive data. NIST says integration of new algorithms into information systems has historically taken 10 to 20 years, while encouraging organizations to begin transitioning now. NIST’s FAQ covers the transition guidance and historical timeframe.

Use these questions to decide where to focus first:
Rank #3
- Certified to FIPS 197 - U.S. Government Approved High Level Information Security Standard.
- Protection against brute force password attacks - Data is automatically erased after 6 unsuccessful access attempts. The data of the USB flash drive type c encryption with dual connectors is destroyed and the cryptographic drive is reset.
- Durable dual-layer waterproof design* — Protects the crypto reader from bumps, drops, run-in and immersion in water. The electronics are protected by a hardened internal case. Rubberized silicone outer case provides a final layer of protection.
- Auto-Lock —The cryptographic key automatically encrypts all data and locks when removed from a PC/Mac or when screen protection or "computer lock" is enabled.
- Secure Entry —Data on these flash drives cannot be accessed without the correct alphanumeric password of 8 to 16 characters. A password indication option is available for this flash drive. The hint cannot match the password.
- How long must the information remain confidential? Data that would still be sensitive many years from now deserves earlier attention.
- Does the system use public-key cryptography? Identify the algorithms and cryptographic assets rather than assuming all encryption has the same exposure.
- What would compromise mean? Consider the impact and exposure of the system, not just the technical difficulty of changing it.
- Can the vendor support a transition? A roadmap depends on products, services, and suppliers that participate in protecting the data.
The point is not to predict the arrival date of a future quantum computer. It is to avoid leaving long-lived sensitive information in systems whose cryptographic dependencies and migration plans are unknown.
