Summary: dovecot SHA256 problem

Initial Comment:
I tried using dovecot:SHA256 to hash my passwords.
I finally got it working after some code modifications.
For one dovecotpw is now doveadm pw.
I generated my hash using doveadm pw -s SHA256 and updated the database.
PostfixAdmin would not log in and threw no errors. After echoing the hash that PFA was generating I realized two things:
The PFA generated hash trims the encryption scheme (whats the purpose?). This creates problems for dovecot when using a SHA hash.
The PFA generated hash has a new line character "\n" at the end.

To fix the hashing issues I made the following change:
MODIFIED THIS LINE:
$password = trim(str_replace('{' . $method . '}', '', $password));
TO THIS:
$password = rtrim($password);

Now I am able to keep the encryption scheme in the database and the modified code trims the newline character off the end of the hash.
