Authenticated AES-256-GCM

Encrypt sensitive photos, tax records, and documents using military-grade AES-GCM encryption with PBKDF2 key derivation.

Self-Contained Local Vault

Bundle multiple sensitive files into a single encrypted vault file (.vault) that you can store on USB or cloud drives safely.

Zero Cloud Key Storage

We never see, store, or transmit your master passphrase. Even if our servers were seized, your locked files remain unbreakable.

Frequently Asked Questions
Can anyone (including Tangent) decrypt my files without the password?

No. The encryption key is derived directly from your password using PBKDF2 with 100,000 iterations and AES-GCM 256-bit cryptography. Without the password, mathematical decryption is virtually impossible.

What encryption standard does File Vault use?

It uses Web Crypto API authenticated AES-GCM (Galois/Counter Mode) with 256-bit keys and cryptographic random initialization vectors (IV) for every encryption pass.

Can I decrypt my vault offline on another computer?

Yes. Because File Vault uses open web cryptography standards, you can open Tangent on any computer (even offline) and unlock your files instantly.
