Hi all, I'm using Ubuntu 14.04 and I use ecryptfs to encrypt arbitrary directories; to mount the directories I use a command like this: sudo mount -t ecryptfs .secret/ secret/ -o key=passphrase,ecryptfs_cipher=aes,ecryptfs_key_bytes=32,ecryptfs_passthrough=n,ecryptfs_enable_filename_crypto=n The thing is that, somehow, I messed it up when pasting the password on the first mount in one of the directories (yeah, I know that the message saying that I've never mounted with that key before should have been quite clarifying)...copied all the data and unmounted it. Now, when I mount it and try to read files I get errors and messages like this in dmesg: [ 4210.614158] ecryptfs_parse_options: eCryptfs: unrecognized option [ecryptfs_debug=5] [ 4215.347261] Could not find key with description: [306437480dxxxxxx] [ 4215.347269] process_request_key_err: No key [ 4215.347272] ecryptfs_parse_packet_set: Could not find a usable authentication token [ 4215.347277] Valid eCryptfs headers not found in file header region or xattr region, inode 919485 After downloading the code of the Ubuntu package I found out that in the directory tests/userspace there were the tests for verifying passphase signs, so I thought that I could use that to iterate through mutations of the pasted passphrase in the hope of reproducing the mess I provoked. The problem I'm having is that the test program expects four parameters: pass salt expected_sig expected_fekek But since in my configuration I don't have a "file encryption key, encryption key" I don't know how I could modify it in order to try to find my passphrase; or should I use any other executable from ecryptfs?
