pw

A simple command-line password handler written in haskell.

Todo

• not encrypt the tag for faster lookup.
• more options for -generate?
• ability to choose encryption?

Notes

• The passwords are encrypted with AES in OFB mode. Where the key and iv are created with the master passphrase
• The filehandling tests won't run on Windows, but I think it works.
