Encrypted zip files on OSX
Update: I've since switched to KeePassXC, the community fork of KeePassX, an open source, cross-platorm, local-first, encrypted password storage program.
My passwords and other miscellany are in a plain text file within an encrypted zip. Since starting to use OSX I've been looking for a way to access my passwords such that:
- I get prompted for the decryption password.
- The file gets unzipped, but not in the same directory, because that's synced to Dropbox, so would send my plaintext passwords to them every time I accessed them. Maybe to /tmp?
- The plaintext file within the zip is opened in \$EDITOR.
- Wait for me to close \$EDITOR, then remove my plaintext passwords from the filesystem.
- Before deleting the passwords, check if I've updated them. If so, put the new updated version back into the original zip file.
- Don't forget to keep the updated zip file encrypted, using the same password as before, without prompting for it again.
I failed to find an existing app which would do all this (although I had no trouble on Linux or even on Windows.) Hence, resorting to good old Bash:
#!/bin/bash ZIPDIR="$HOME/docs/org" read -s -p "Password:" key cd $ZIPDIR unzip -P $key passwords.zip passwords.txt -d $TMPDIR if [[ $? != 0 ]] ; then exit 1 fi cd "$TMPDIR" touch passwords.datestamp $EDITOR passwords.txt if [[ passwords.txt -nt passwords.datestamp ]] ; then zip -P $key -r "$ZIPDIR/passwords.zip" passwords.txt fi rm passwords.txt rm passwords.datestamp
I don't expect this to be watertight, but seems good enough for today. I'm happy to hear suggestions.
