# Post-Quantum Encrypted Cloud Storage for Long-Term Privacy # Post-Quantum Encrypted Cloud Storage ML-KEM+AES-256 on Every Upload [Post quantum encryption](/post-quantum-encryption/) protects your files today, tomorrow and against future quantum threats that are designed to steal your private data. DragBin's [client side](/client-side-encryption/), quantum resistant encryption (ML-KEM + AES-256) offers security from Harvest Now, Decrypt Later threats and complete privacy in a zero knowledge security architecture. [Try DragBin Free](https://app.dragbin.com/signup)[Read Security Whitepaper](/whitepaper.pdf) ## Why You Need Post-Quantum Encryption for Cloud Storage [End-to-end encryption](/end-to-end-encryption/) is not enough for encrypted cloud storage because it cannot combat the threats posed by quantum computers. Google itself has [set a 2029 timeline](https://blog.google/innovation-and-ai/technology/safety-security/cryptography-migration-timeline/) for post quantum migration, urging people to adopt post quantum solutions. For this reason, DragBin's post quantum encrypted cloud storage offers both to enhance security. ### [Harvest Now, Decrypt Later](/harvest-now-decrypt-later/) Attackers can collect encrypted data today and store it until future advances in computing make it possible to decrypt. This means sensitive information intercepted today could become readable years later, even if it is currently protected by encryption. ### Quantum Threat to RSA and ECC A sufficiently powerful quantum computer could use Shor's algorithm to break widely used public-key cryptography such as RSA and ECC. Since these algorithms help secure key exchange and digital signatures, their compromise could expose encrypted communications and undermine digital trust. ### Long-Term Data Protection Sensitive data that must remain confidential for years needs post-quantum cryptography to withstand future advances in computing. Protecting data means securing not just the files themselves but also the cryptographic keys used to access them. ## How DragBin's Post-Quantum Encryption Protects Your Cloud Files As one of the best post-quantum encrypted cloud storage platforms out there, DragBin offers complete file privacy and top-notch security. Our zero knowledge cloud storage does not store or manage your encryption keys. You are the sovereign master of your own files and nobody can see them - not even the employees of DragBin. ### MLKEM Key Encapsulation Quantum-resistant key encapsulation mechanism securing asymmetric key exchanges against future threats. ### AES-256 Encryption Industry-standard symmetric encryption with 256-bit keys. Your files are encrypted in transit and at rest. ### Argon2 Key Derivation Winner of the Password Hashing Competition. Securely derives keys from your password with high computational cost. With complete metadata protection and a [zero knowledge security architecture](/zero-knowledge-encryption/), your confidential files are completely safe. Post quantum encryption is an additional layer of security that protects your data further. Whether it's recently stored files or ten years down the line, your data will always be secure and private to you. ## Secure File Sharing With Granular Access Controls Protect all your shared files with [password protection, expiring links, view and download limits](/features/secure-file-sharing/), one-time watch, geo-restrictions among others. Get detailed analytics and track every click on the file you shared. [Secure folder sharing](/blog/folder-sharing/) allows you to share larger folders while keeping privacy as the top priority. ### Link Analytics LiveLast AccessedMar 4, 2026, 2:14 PMTotal Views 0 Unique Views 0 Downloads 0 Sessions 0 Views Over Time ViewsUniqueDriveDropboxOneDriveS3AWS S3PrAePsAiFHCDrDragBinAny cloud - Any app - Anywhere ## Manage and Access Files Across Your Devices Access your files across devices without worrying about file size restrictions.
