Re: Encrypted file transfer
I found a good solution for my problem... I copied the compiled ELF file of gnupg (/usr/bin/gpg) to $HOME/bin Then I copied the libraries it needs to $HOME/lib Created ~/.gnupg/ and copied pubring.gpg into it So, to execute gnupg I need to set up the variable to look for libraries in a non default diretory: export LD_LIBRARY_PATH=~/lib After than, 'gpg' is working right, so I set up a script and put it in cron, to execute once a day. #!/bin/sh export LD_LIBRARY_PATH=~/lib cat myfile | ~/bin/gpg --batch --no-tty --armor --quiet --encrypt --always-trust --recipient [EMAIL PROTECTED] | mail -s "my files" [EMAIL PROTECTED] So, I receive some files I have in a remote computer encrypted by mail. :-) On Tue, Jan 02, 2001 at 01:52:59PM -0500, hpknight wrote: If you use RSA keys, scp can run non-interactively.
