GNATS password management

[Yngve Svendsen <yngve dot svendsen at clustra dot com>]

Below is an outline of the two password-management tools I'd like to see 
implemented for GNATS 4. gnats-pwconv is intended for upgraders from 
version 3 to version 4, while gnats-pw partially mimics the functionality 
of Apache's htpasswd tool.

What do you all think?

gnats-pwconv
gnats-pwconv [-mp] infile outfile
gnats-pwconv -n[mp] infile

Converts the plaintext passwords in the GNATS 3 password file infile and 
writes the resulting complete version 4 password file to outfile. 
Infile=outfile should be disallowed.

-m, --md5	Use MD5 encryption, i.e. convert passwords to MD5 and add $1$ prefix
-n, --nocreate	Don't create file; display results on stdout.
-d, --crypt	Force CRYPT encryption of the passwords (default).
-p, --plaintext	Do not encrypt the passwords (plaintext). Prefixes existing 
passwords with $0$
-t, --test	Tests which encryption methods are supported by the system
-h --help
-V --version



gnats-pw
gnats-pw [-cmdps] passwordfile username accesslevel
gnats-pw -n[mdps] username accesslevel

Prompts for a password (twice), then inserts or edits the corresponding 
entry in the specified passwordfile. If the -n option is given, the 
resulting passwordfile entry is written to stdout instead.

-c, --create	Create a new file.
-n, --noupdate	Don't update file; display results on stdout.
-m, --md5	Force MD5 encryption of the password, i.e. convert the password 
to MD5 and add $1$ prefix
-d, --crypt	Force CRYPT encryption of the password (default).
-p, --plaintext	Do not encrypt the password (plaintext). Prefixes the 
entered password with $0$
-h, --help
-V, --version
