Secure File Transfer, Reimagined.
Sencrypt enables lightning-fast, end-to-end encrypted file sharing. Your files are encrypted on-device before they ever touch our servers.
Security First
Everything You Need for Secure Transfer
- On-Device Encryption
Files are encrypted using AES-256 directly in your browser. Our servers only see encrypted blobs. Your privacy is mathematically guaranteed.
- Large File Support
Sending a 4GB file? No problem. Sencrypt splits large files into 10MB encrypted chunks for reliable, resumable, and ultra-fast uploads.
- Verified Recipients
Only users with a registered public key can receive files. This ensures your data doesn't just go to a link, it goes to a person.
Deep Dive
How Sencrypt Protects Your Data
We use industry-standard hybrid encryption to ensure that your files are only accessible to you and your intended recipient.
Client-Side Encryption
Your file is split into 10MB chunks and encrypted using AES-256-GCM directly in your browser. Raw data never leaves your device.
Secure Key Wrapping
A random session key is generated and then 'wrapped' using the recipient's RSA-OAEP Public Key. Only they can unlock it.
Encrypted Transfer
Only encrypted blobs and the wrapped session key are uploaded to our servers. We have zero knowledge of your content.
Peer-to-Peer Privacy
The recipient uses their Private Key to unwrap the session key and decrypt chunks back into the original file.
