What makes these programs different is the fact that they make it easy to encrypt files before uploading to cloud storage they streamline the process. In terms of encryption, all of the following programs are nothing unique they encrypt files just like other encryption utilities. FREE CLOUD STORAGE FILE ENCRYPTION SOFTWARE That is why we have put together a list of three programs which can be used to do just that. So if you use cloud storage, you probably want to check out an encryption program specifically designed to help streamline encryption of files you are going to store in the cloud. They can be used to protect files stored in cloud storage yes, but they aren’t specifically designed for cloud storage files. However, most encryption programs don’t have the cloud storage model in mind. There are plenty of encryption programs out there, such as dotTech’s favorite TrueCrypt and AxCrypt. The second best way to address these concerns is by using encryption.Įncryption helps insure that even if your files are accessed by an unauthorized person, they won’t be able be able to open/read them (assuming you used a strong password and proper encryption). However, I’m sure that isn’t an option for some people. The best way to combat these concerns is to simply not use cloud storage. One of the major concerns with cloud storage is the safety and privacy of data no one wants their files, documents, etc. However this can limit can be circumvented by specific apps if the library \(()\) is used for file system calls.I’m sure many dotTechies use cloud storage service, at least sparingly if not frequently. The NTFS specification according to () allows for up to 32000 characters in a file name and is actually artificially limited in windows APIs to 260 characters. *Originally posted by:* have been following your work with interest for a while now while now and would like to personally thank you for all the effort you have put into the cryptsync project. I would therefore like to ask if you could test this library with your cryptsync project and see if it works as this would resolve the filepath/name limitation when encrypted filenames are used.Īgain, thanks for your continued work on this project. The Delimon pages posits that implementing their process in existing projects should be straight forward. However this can limit can be circumvented by specific apps if the library ( ) is used for file system calls.Ī proof of concept is also demonstrated using the delimon Win32 Explorer which works remarkably well for long file names.įor example I've created 573 character paths using the delimon win32 explorer, copied files to these paths and removed them without issue.Ĭryptsync conducts this very same process but runs into issues because of the aforementioned limits when encrypted filenames are used. The NTFS specification according to allows for up to 32000 characters in a file name and is actually artificially limited in windows APIs to 260 characters. I am currently using it and ran into the issue that occurs if Long File names are used and the resulting encrypted file names that reach and sometimes exceed windows 260 character limit. Originally posted by: have been following your work with interest for a while now while now and would like to personally thank you for all the effort you have put into the cryptsync project. What version of the product are you using? On what operating system? Sure, its a bit harder than just encrypting the filename/dirname itself, but it gets around the limit of characters.Īnd it could also let you embed further information within the metadata file such as a MD5 of the original file, which could be used for verification/comparison to see if the original has changed. Thus if a directory was scrambled to "dir000001" then in that dir there might be a "dir0000001.crypt" that would contain the real name of that directory. Then, when the files are being decrypted, this can be extracted from the 7zip and used in restoring the file.įor directories, an encrypted 7zip file that only contains metadata for the directory name could be used, with a rule for example that the file has to match the name of the parent directory. In reality, you don't want the filename encrypted, you just want it hidden, so instead of encrypting the filename itself, just use a randomized name (file00000001.crypt) and embed a metadata file within the encyrpted 7zip that contains the real filename. Originally created by: steps will reproduce the problem?Ĭurrently filename encryption cannot support long paths due to the character limitation of the filesystems.
