Hello,
Is this the proper place to suggest an enhancement for the stock dovecot package ?
The enhancement would be the following:
For the time being, the dovecotpw utility offers a standardised way to interactively encode a user password in a certain scheme, say:
dovecotpw -s CRYPT Enter new passord: Re-enter new password: etc.
Given a *valid* /etc/imap.passwd file (passwd-file authentication), dovecotpw should be able to process it non-interactively and output another text file with all {PLAIN} passwords converted in the specified <scheme>, i.e.:
dovecotpwd -s CRYPT if=/etc/imap.passwd of=/etc/imap.passwd.converted
where /etc/imap.passwd.converted have the previously {PLAIN} passwords converted in scheme CRYPT.
Passwords that were previously encrypted in other schemes than {PLAIN} shoud remain untouched.
That will allow quick securing of old legacy /etc/imap.passwd files.
Get a fresh cup of coffee and start your favorite editor. Pseudo code
infile := /etc/imap.passwd
outfile := /etc/imap.passwd.converted
infilehandle := open(infile)
outfilehandle := (outfile)
loop over lines from infilehandle
when looks_like_plain(current_line)
current_line := crypt_line(current_line)
write_line(current_line, outfilehandle)
write(outfilehandle)
close(infilehandle)
close(outfilehandle)The function looks_like_plain splits the line at the colon and checks if the content n-the field is {PLAIN}. crypt_line takes the line, splits it, crypts the password an returns a line with a crypted password.
Or define crypt_line the way, it returns the line as it comes in, if the password is crypted already, if the password is plain, do it as described above.
