One example of a method to do this is
/usr/bin/openssl des3 -e -salt -in <file> -out <file>.des3
/bin/rm -i <file>
for encrypting and
/usr/bin/openssl des3 -d -in <file>.des3 -out <file>
for decrypting. I use these a lot. Don't forget the -salt, the man
page emphasizes that omitting it makes the encryption weaker.
Is the existing pass-phrase protection weak in some way, by the way?
I'd certainly want to know... Or do you just sometimes have to use
the DSA key and its pass-phrase on an untrusted machine?
