![]() If you add a file to a shared folder, the persons who you shared the folder with can access the file now, too.Įncrypted and permission to access for AliceĮncrypted and permission to access for BobĮncrypted and permission to access for Alice and Bob Just as the inheritance of encryption properties, permissions are inherited from the parent folder as well. If you share access to multiple files, make sure that they are all synchronized completely. Keep in mind that it must be synchronized by your cloud provider. Note: Every time you share a file, the file is modified. ![]() If you share the file with somebody, the key will be encrypted with the Boxcryptor account of the receiver and stored in the file as well. The key is encrypted by your Boxcryptor account and is stored within the file itself. Share the cryptographic key in Boxcryptor.Please check your provider’s documentation on how to share files or folders with others. Share the file physically at your cloud provider.Īs a consequence, there are two steps necessary to share an encrypted file: The other person can read the information, but it is useless, since it does not have any semantic meaning. Therefore, sharing an encrypted file with somebody is like writing an email by poking around on your keyboard. To decrypt the information again, you need a cryptographic key that translates the information back into its original state. For programs and humans the encrypted information is rendered useless. If you encrypt a file, however, the information inside the file is modified. Such a file can be read or modified by anyone who has physical access. If you store an unencrypted file on your device or in the cloud, the program you store it with saves the file and the information inside. Safe is another tool in this ecosystem and the main goal is to help more people take control of how their data is stored and transmitted and hopefully bootstrap mainstream digital privacy awareness.For understanding how the sharing of encrypted files works, it is helpful to understand how programs handle unencrypted and encrypted files. I use both depending on the nature of the data I'm keeping private. They are different tools for different situations. Don't just take my word for it, verify yourself. I can guarantee that no data is cached to the local disk unencrypted when using Safe. Safe just chooses the most secure defaults.Īs for your second concern about caching. TrueCrypt is very intimidating to set up for people who don't intimately understand how cryptography works. Try making a new encrypted disk with TrueCrypt, then do the same process with Safe and you'll see what I mean. I designed Safe to be much easier than TrueCrypt to use. This affects the performance of algorithms focused on caching and deduplication.ģ. all data is stored as a single potentially giant file. Most of their drivers/protocols are file-based. ![]() 1:1 File encryption is much faster on network storage you don't control, like NFS, SMB, Drobo, Space Monkey, Dropbox, Google Drive. You can use your existing EncFS encrypted data on Mac/Windows.Ģ. That's just me, Safe is GPL and comes with no warranty :) Personally I store all my tax, legal, and medical documents in Safe. If you need a steel alloy vault, TrueCrypt might be closer to what you're looking for but it's not without its own set of limitations as well. Think of it like the physical safe you keep in your home: burglars will have a hard time cracking it but given enough resources it's not strictly impenetrable. As a tool, it empowers more people to make their own cryptography decisions instead of having to rely on and trust proprietary solutions. Peace of mind if your laptop or external hard gets stolen, or someone hacks into your backup service. a simple way to ensure reasonably private stuff is actually stored privately. Safe's main goal is to make file system encryption easy to use and accessible to more people. It's not for hardcore cryptographic applications, you can't choose specific ciphers and it makes no effort to ensure plausible deniability. Safe forms an ecosystem with similar tools like TrueCrypt. It's called Safe, it's free and you can get it here: Wanted to announce the release of my native Windows/MacOSX port of EncFS. Here's the announcement from a few days ago, linked from Safe's Twitter feed:
