Hello, I've posted a question on Crypto Stack Exchange and someone suggested that I asked here. This is my first time using a mailing list so I don't know if this is the right way to do it. I have about two years of ecryptfs backups and I need to find for a specific deleted file that probably was on one of these backups. I made a list of all the filenames but don't know how to decrypt/decode them in any way. Found already the key using keyctl but don't know what is the next step but read something about parse tag 70 (?). As there is a lot of backups it would be very time consuming to extract, mount all of them and search for a file. I don't have a lot of programming skills beside the very basics but I'm willing to learn if it's necessary but thought that must have any command like " openssl *** " that can help me. English is not my primary language so if it needs more explaining I'll be glad to reformulate. Question on Crypto Stack Exchange (but I believe this email is a lot better on the explaining side): https://crypto.stackexchange.com/questions/75500/how-to-decode-decrypt-ecryptfs-filename Thanks in advance!
