  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?
