ShardHex vs Cryptomator
These tools are often discussed together, but they solve genuinely different problems. This page lays out where each one fits — and where you might want both.
Quick verdict
Cryptomator encrypts a folder before it syncs to one cloud — keeping that cloud blind to your contents. ShardHex splits an encrypted file across multiple clouds with mathematical redundancy — surviving any single cloud's deletion or ban. They are complementary, not competing. Use Cryptomator if you trust your one cloud; use ShardHex if you can't afford to.
Side-by-side comparison
| Property | Cryptomator | ShardHex |
|---|---|---|
| Primary use | Encrypt a folder for sync to one cloud | Split a file with parity across many clouds |
| Encryption | AES-256-GCM, client-side | AES-256-CTR, client-side |
| Redundancy across providers | None — single cloud | Reed-Solomon N-of-K, up to 12 clouds |
| Survives losing a cloud | No — vault dies with the cloud | Yes — any K of N shards restore |
| Sync model | Continuous, file-system mounted | Snapshot, on-demand |
| Steganography | No | Yes (hide shards in JPG/PNG/MP4) |
| Open source | Yes (GPL) | No (source-available not planned) |
| Platforms | Win / Mac / Linux / iOS / Android | Windows (Mac/Linux planned) |
| Pricing | Free desktop; €5–10/mo Cryptomator Hub for teams | Free local; $19.99 one-time Pro for cloud |
| Project maturity | Mature, large dev team, audited | Young, single dev, unaudited |
| Best for | Daily-edited files synced to a trusted cloud | Important snapshots that must survive any one cloud disappearing |
What each tool actually does
Cryptomator
Cryptomator creates an encrypted "vault" — a folder that looks unintelligible to anyone but you. You drag files into it, it transparently encrypts them with AES-256-GCM, and you point your cloud sync client (Google Drive, OneDrive, Dropbox, anything that syncs a folder) at the vault.
The cloud sees only encrypted blobs and can't tell what you stored. You see the vault as a normal mounted drive when you unlock it. It's a clean, well-engineered solution to "I want cloud storage without the cloud reading my files".
Cryptomator is open source (GPL), has been independently security-audited, and runs on every major desktop and mobile platform.
ShardHex
ShardHex doesn't sync. It takes a single file and splits it into N erasure-coded shards (using Reed-Solomon, the same math behind RAID 6 and QR codes). Each shard is AES-256 encrypted before leaving your device, and gets uploaded to a different cloud provider.
The point is redundancy across providers, not encryption per se. If Google bans your account, OneDrive deletes your data, or Dropbox suspends your subscription, you still have shards on K other providers — and any K of the N total are mathematically enough to reconstruct the original file.
ShardHex is a snapshot tool, not a sync tool. You upload a file once; if it changes, you re-split and re-upload. Currently Windows-only, single-developer-maintained, source-available not planned.
When Cryptomator is the right answer
- You have one cloud you basically trust (paid Google Workspace, iCloud Plus, paid Dropbox), and the worry is just "I don't want them reading my files".
- You're editing files daily and need them to sync continuously across your devices.
- You're on Mac, Linux, iOS, or Android — ShardHex isn't there yet.
- You want a fully open-source, audited tool with a long track record.
- You want zero monthly cost (Cryptomator desktop is free; you only pay for the cloud you sync to).
- The cost of "this one cloud disappears entirely" is acceptable to you.
When ShardHex is the right answer
- You've experienced or know someone who experienced a cloud account ban, deletion, or "policy violation" wipeout — and you can't afford a repeat.
- The data is important enough that "single cloud disappearing" is unacceptable.
- You already have multiple cloud accounts (free or paid) and want to use them as a single resilient backup target.
- You want snapshot backups of important files (documents, photos, media archives) — not continuous sync of working folders.
- You're on Windows.
- The steganography option (hiding shards inside ordinary photos) is useful to you — for example, when an obviously-encrypted blob would itself attract scrutiny.
Can you use both? Yes — and it's actually smart.
The two tools cover different layers of the cloud-storage problem. A reasonable combined setup:
- Cryptomator for daily-edited files: working documents, code repositories, source media. The vault syncs continuously to your one trusted cloud.
- ShardHex for important snapshots: tax records, photo archives, recovery keys, family videos, anything where "the next 20 years" matters more than "the next minute". Periodically (monthly or quarterly), split these and scatter shards across multiple clouds.
This is "belt and suspenders": Cryptomator handles everyday cloud privacy with low friction, ShardHex handles disaster recovery for the things that truly matter. The two never collide because they target different files.
Honest summary
Cryptomator is a much more mature project. If you're building your first encrypted-cloud setup and only need one cloud, start there. ShardHex doesn't replace it.
ShardHex solves a problem Cryptomator doesn't try to solve — surviving the loss of an entire cloud provider — at the cost of being newer, narrower in platform support, and not open source. If that specific problem matches your situation, ShardHex is worth $19.99 one-time. If it doesn't, Cryptomator alone is probably enough.
