End-to-end encryption
Content is encrypted in your browser before it ever leaves your device. We never see your plaintext.
Your sensitive information is encrypted in your browser, shared through a single-use link, and destroyed the moment it's read.
Create a secretBuilt from the ground up for security-conscious teams and individuals who refuse to compromise on privacy.
Content is encrypted in your browser before it ever leaves your device. We never see your plaintext.
Secrets self-destruct immediately after they are viewed. No copies, no traces, no recovery.
Set precise expiration windows from 1 minute to 7 days. Expired secrets are purged automatically.
Add a passphrase that the recipient must enter. Failed attempts trigger automatic lockout.
Every secret is tied to your account. Revoke any link instantly from your dashboard.
The server stores only encrypted blobs. Even with database access, secrets remain unreadable.
No complex setup. No installations. Just write, share, and forget.
Paste credentials, API keys, or any sensitive text. Choose expiry, password, and attempt limits.
Locker encrypts everything in your browser and generates a unique URL you can share anywhere.
Once the recipient reads it, the secret is permanently destroyed. No one can access it again.
Locker uses a zero-knowledge architecture where encryption and decryption happen entirely in the browser. The encryption key lives in the URL fragment — a part browsers never send to servers.
Client-side AES-256-GCM
Industry-standard authenticated encryption performed in your browser.
Encrypted-at-rest storage
Only ciphertext is stored. The decryption key never reaches the server.
Automatic purge on access
Secrets are permanently deleted after first successful retrieval.
Slack messages persist forever. Emails get forwarded. Locker gives you a secure, self-destructing alternative.
