file encryption and integrity check

[Roscoe]

Sure will.

gpg -c is what you want.

Make sure you are using a MDC, which means either using one of the
128bit blocksize ciphers (your gpg will probably use AES256 by
default, which is good - gpg -vc to find out) or passing the
--force-mdc option.


If you want protection in the way of recovering from random bit errors
rather than just detecting them, running par2 against the encrypted
archive might be the way to go.
