If you're happy with the command line, using something like pass (https://www.passwordstore.org/ https://www.passwordstore.org/) is worth serious consideration rather than rolling your own. It is GPLv2 and has a number of benefits, including the fact that your passwords are stored encrypted in a git repo and if you do "pass edit" it will call out to $EDITOR to do your edits, putting encryption/decryption and git transparently on both sides.
