I want to backup my crypto wallet keys securely somewhere. Is there an app/open source lib that can help me encrypt and save a directory to google drive or dropbox or somewhere else ?
- 7-zip is really easy and free to use. You can put your files into a 7-zip archive and then password protect them. It will encrypt the zip with strong AES-256 encryption. You can then move the zip to the cloud and store it there or share to others and they will only need 7zip ( free and easy to use ) instead of learning or paying for other software.
- Our startup Kalepso is bringing to the market a quantum-proof solution for encrypted data storage on any cloud. With our solution, you don't have to give your keys to the cloud providers, and we are the only ones to combine dynamic re-encryption with differential privacy. Let me know if you are interested, and I can give you free early access.
