Could you please help me find a good file encryption tool? The target OS is Linux, but tools for Windows are welcome, too. FOSS tools are preferred. The tool must be reliable both for the recovery of the original data (on decryption) and security-wise. The encrypted file is to be used only by myself.
It would be very nice if the tool had a slow and/or a resource-intensive password derivation scheme like the used in bcrypt, scrypt or KeePass.
- I'm not interested in an encrypted filesystem.
- I'm not interested in an encrypted (virtual or not) disk or partition.
- Plausible deniability is not an issue.
Additional question: considering that the encrypted files could be made available freely online, some problems arise (eg the evolution of the computational power). What other security measures (besides the encryption per se) would you advise to be taken (eg password/key lenght, tool configuration etc)?
