Drop in sensitive notes, passwords, or API keys. CipherSend creates a single-use link that expires automatically after it is viewed once or 24 hours have passed.
Client-side encryption
Optionally seal secrets with your own passphrase.
Automatic burnout
Secrets delete themselves after viewing or 24h.
We've stripped away everything that gets in the way of secure sharing. No accounts, no tracking, just encryption.
Secrets are encrypted before storage. We only keep the minimum metadata needed to orchestrate delivery and expiration.
Each URL self-destructs after a single open, preventing secrets from floating around in inboxes and chats.
No onboarding or account switch. Paste a secret, share the link, and get back to work in seconds.
Drop the message into the form. Add your own passphrase if you want client-side encryption.
Send the generated one-time link to the recipient through your favorite channel.
Once opened, the secret burns itself. Unopened links vanish after 24 hours automatically.
CipherSend is completely free to use with no hidden costs. Share secrets securely without limits.
Perfect for individuals and casual sharing
For power users who need more control
For teams with advanced security needs
CipherSend uses industry-standard encryption to protect your secrets. When you enable client-side encryption, your data is encrypted in your browser before it ever reaches our servers, ensuring zero-knowledge security. All secrets are automatically deleted after first access or 24 hours, whichever comes first.
No! CipherSend is designed to be completely frictionless. Neither you nor your recipients need to create an account or sign in. Simply create a secret, share the link, and you're done.
All secrets automatically expire after 24 hours, even if they're never opened. This ensures that forgotten or undelivered links don't remain accessible indefinitely. The secret and all associated data are permanently deleted.
Currently, CipherSend is optimized for sharing text-based secrets like passwords, API keys, and sensitive notes. File sharing capabilities are on our roadmap for future releases.
Choose a strong, unique passphrase that you can share with the recipient through a different channel (like a phone call or separate message). Avoid using passwords you've used elsewhere. For maximum security, use a random passphrase generator.
Yes! CipherSend is completely free to use with no limits on the number of secrets you can create. We believe secure secret sharing should be accessible to everyone. We're exploring premium features for power users in the future, but the core functionality will always remain free.
