dovecotpw

       word scheme.

SYNOPSIS
       dovecotpw [-l] [-p <password>] [-s <scheme>] [-u <user>] [-V]

DESCRIPTION
       dovecotpw is a small tool to easily generate passwords for a  specified
       password scheme known by  dovecot(1).  A password scheme means the for-
       mat in which any password is stored in password databases.

       The main idea behind storing passwords in non-plaintext scheme is  that
       if an attacker gets access to your server, he can't easily just get all
       users' passwords and start using them. With stronger schemes  it  takes
       more time to crack the passwords.

       Currently,  the  password schemes supported by dovecotpw are: CRYPT MD5
       MD5-CRYPT SHA SHA1 SMD5 SSHA PLAIN CLEARTEXT CRAM-MD5 HMAC-MD5  DIGEST-
       MD5 PLAIN-MD4 PLAIN-MD5 LDAP-MD5 LANMAN NTLM RPA.

       dovecotpw  can be used to populate dovecot(1) password databases.

OPTIONS
       -l     List known password schemes.

       -p <password>
              Use  <password> as the password to be encoded with the specified
              scheme. If this option is not used, you  are  prompted  for  one
              interactively.

       -s <scheme>
              Specify  the password scheme to be used to encrypt the password.
              <scheme> must be one of the supported password scheme as  listed
              here  above. If you omit this option, the default scheme is used
              (HMAC-MD5).

       -u <user>
              Specify the username. This can be needed by some schemes.

       -V     Internally verify the generated hash.
