Encrypt
Choose an algorithm, provide data, and generate a protected result with a key you can store separately.
Cryptographic operations platform
Put sensitive data behind a real perimeter.
Encrypt text and files, retain custody of the key, and control every protected asset from a hardened private workspace.
- Authenticated encryption
- User-controlled keys
- Role-based oversight
Verified security stack
Protection is active at every boundary.
Four independent controls protect the path from sign-in to ciphertext release.

Enforced separation
The ciphertext and its key never share a trust boundary.
CipherSphere keeps protection steps explicit: encrypt the payload, take custody of the key, and release plaintext only after integrity verification.

- Envelope sealedAuthenticated encryption binds content and metadata.
- Custody transferredThe encryption key remains under user control.
- Integrity enforcedModified ciphertext is rejected before release.
Operational sequence
A controlled protection workflow
Each stage has one purpose, one owner, and a clear security boundary.
Retain custody
Save encrypted files to your vault and review the algorithm, size, owner, and creation date.
Authorize access
Give a named user explicit permissions and an expiry instead of sending untracked copies.
Verify and recover
Supply the protected data and matching key, then copy text or download the restored file.
Initialize workspace
Control the data before it leaves your hands.
Create a private workspace and generate your first authenticated encrypted asset.
