Proposal, "password" command for PBE keyset password management

[GoogleCodeExporter]

If you want to manage a PBE keyset with c++ keyczar tool, once a password is 
added you can change or remove it.

:> KeyczarTool password
Requires: location

'password' - Adds, changes, or removes password from PBE keyset.

Expected usage: KeyczarTool.exe password <options>
<options> available:
  -l, --location=VALUE       The location of the key set.
  -r, --remove               Remove password from the key set. 

Would prompt one for existing password, if it exists, if --remove flag is not 
set, would then prompt twice for new password.

This seems like an interesting feature. I think it would best be combined with 
a feature that allowed for the manipulation of encrypted keysets. Perhaps 
something like:

:> KeyczarTool keycrypter
Requires: location

'keycrypter' - Adds, changes, or removes encryption from keyset.

Expected usage: KeyczarTool.exe keycrypter <options>
<options> available:
  -l, --location=VALUE       The location of the key set.
  --crypter=VALUE            The location of the current crypter, if none assumes pbe
  --newcrypter=VALUE         The location of the new crypter, if none assumes pbe
  -r, --remove               Remove key set encryption. 

Would have similar prompts to your scheme.
