Erasure-coded security for everyone

Split. Scatter.
Secure.

When one cloud bans your account or deletes your data, your backup is already gone. ShardHex splits files into encrypted shards across 13 cloud providers — losing any one of them is just an inconvenience, not a disaster.

Features

Engineered for resilience

Built for the day a cloud provider deletes your data, bans your account, or silently corrupts a file — and you still need it back.

Survives Cloud Outages

Reed-Solomon erasure coding splits your file into N shards across different providers — any K are enough to restore. A single cloud going down, banning your account, or losing your data can't take your files with it.

Provider-Blind Encryption

AES-256-CTR encryption applied client-side before anything leaves your machine. Even if every shard leaks — or every cloud is compromised — the bytes are unreadable without your key.

Hide What You're Hiding

Steganography embeds your encrypted data inside ordinary photos or videos. The carrier opens normally — your data is invisible. Useful when an encrypted blob would itself attract attention.

13 Cloud Providers Supported

Google Drive, OneDrive, Dropbox, MEGA, S3 / R2 / B2 / Wasabi / MinIO, plus free anonymous hosts. Mix and match across consumer and object-storage providers — your manifest tracks what went where.

Parallel & Chunked Transfers

Multi-threaded uploads and HTTP-Range chunked downloads saturate your bandwidth. Auto-retry on transient failures, instant cancellation, per-shard progress.

Detect Tampering & Loss

Every shard carries a SHA-256 checksum. Verify all clouds in one click — silent corruption, mid-transfer flip, or a deleted file are caught before you actually need to restore.

Self-Healing Repair

Missing shards? Download the surviving K, mathematically reconstruct the missing pieces using the original key, and re-upload — restoring full N-of-K redundancy. No data ever touches an unencrypted state.
