Re: [PLUG] Backup packages


Quote from Jungledisk faq, located here

http://www.jungledisk.com/encryption.shtml

"For technically savvy users, here are some details on how Jungle Disk encrypts your files.
Jungle Disk encrypts files that are stored on S3 prior to uploading them using 256-bit AES. AES is an industry (and government) standard and is one of the most well studied and most secure encryption algorithms available. Jungle Disk uses a unique key for each file, and constructs the key using a HMAC that helps protect against certain attacks. Code that demonstrates how data is encrypted/decrypted is available for download on the Jungle Disk Download page under the GPL license.
Jungle Disk adds a special metadata header to each file when it is uploaded. The header identifies the type of encryption used and contains a salt value and a one-way hash of the salted key. This allows Jungle Disk to determine the correct key to use to decrypt the file. Note that without the decryption keys the header is of no use, and you cannot even tell which files are encrypted with which keys unless you possess the keys."

Very interesting...what encryption setup do you use?
