Open CAD, BIM, medical, and enterprise files without paying $300-30K/year for the native software. Gerber Viewer ships first.
Encrypt and decrypt any file with AES-256-GCM in your browser via the Web Crypto API. Passphrase-based, 600k PBKDF2 iterations. No upload, no server.
AES-256-GCM with PBKDF2 key derivation, which is military-grade encryption.
Yes. Anyone with the encrypted file and the correct password can decrypt it using this tool.
Yes. The tool uses the Web Crypto API for cryptographic operations, providing the same security level as native applications.
Two files — a `.enc` containing the raw AES-256-GCM ciphertext and a `.key.json` sidecar holding the PBKDF2 salt, AES-GCM IV, original filename, and algorithm metadata. The recipient unzips the bundle and feeds both files plus the password into the decrypt tool. Switch the Output format toggle to ".encrypted file" if you prefer one self-contained file instead.
