Overview
Comment:GPG encrypt the file and remove plain text files as part of the script

Since that is kind of the point of scripting and automation. Might as
well get the computer to do as much as possible of the task.

#Lastpass2pwman

CLisp script to convert [Lastpass](https://lastpass.com) CSV export to [pwman](http://pwman.sourceforge.net) format.

Mainly done as a little learning exercise in Lisp for me, but also because I use Lastpass and also want to use a command line based password manager. Unfortunately there doesn't seem to be a command line client for Lastpass so I'm going to use pwman and every so often do a one way update of passwords.

## How to use

Developed and tested in SBCL. Use as follows

	sbcl --script /path/to/this/script </path/to/lastpass/export>

The path to the Lastpass export is optional. If not supplied assumes file is called "lastpass.csv" and is in current directory. Exports a file called "pwman.txt" to current directory. This is in plain text and so needs encoding via GPG: 

	gpg -r <yourgpgid@domain.com> -o ~/.pwman.db -e pwman.txt

This will encrypt the file and overwrite the pwman password database. Remember to delete the plain text files afterwards!

#Lastpass2pwman

CLisp script for SBCL to convert [Lastpass](https://lastpass.com) CSV export to [pwman](http://pwman.sourceforge.net) format.

Mainly done as a little learning exercise in Lisp for me, but also because I use Lastpass and also want to use a command line based password manager. Unfortunately there doesn't seem to be a command line client for Lastpass so I'm going to use pwman and every so often do a one way update of passwords.

## How to use

Developed and tested in SBCL. Use as follows

	sbcl --script /path/to/this/script <gpg id used with pwman> </path/to/lastpass/export>

The path to the Lastpass export is optional. If not supplied assumes file is called "lastpass.csv" and is in current directory. The script works by first exporting a plain text file called "pwman.txt" to current directory, however, this is then immediately encrypted via GPG and replaces the `.pwman.db` file. Both plain text files (the Lastpass export and `pwman.txt`) are then deleted - unless an error occurs with the encryption, in which case the script notifies the user and leaves the files.

Changes to lastpass2pwman.lisp.
