       doveadm-mailbox-cryptokey - Mail crypt plugin management


       doveadm  -o  plugin/mail_crypt_private_password=password  [ -Dv ][ -f formatter ]  mailbox
       cryptokey export|generate|list|password [ -u username | -A ][ -S ][  -F  file  ]  [  other
       options ]


       Generate new keypair for user or folder. The new keypair is marked as active.



       -A     If  the  -A  option is present, the command will be performed for all users.  Using
              this option in combination with system users from userdb { driver = passwd } is not
              recommended,  because  it  contains  also  users  with  a  lower  UID  than the one
              configured with the first_valid_uid setting.

              When the SQL userdb module is used make sure  that  the  iterate_query  setting  in
              /etc/dovecot/dovecot-sql.conf.ext  matches  your  database  layout.  When using the
              LDAP userdb module, make sure that the iterate_attrs and iterate_filter settings in
              /etc/dovecot/dovecot-ldap.conf.ext  match  your  LDAP schema.  Otherwise doveadm(1)
              will be unable to iterate over all users.

       -F file
              Execute the command for all the users in the file.   This  is  similar  to  the  -A
              option,  but  instead  of  getting the list of users from the userdb, they are read
              from the given file.  The file contains one username per line.

       -S socket_path
              The option's argument is either an absolute path to a local UNIX domain socket,  or
              a  hostname  and  port (hostname:port), in order to connect a remote host via a TCP

              This allows an administrator to execute doveadm(1) mail commands through the  given

       -u user/mask
              Run  the  command  only  for the given user.  It's also possible to use '*' and '?'
              wildcards (e.g. -u *
              When neither the -A option, nor the -F file option, nor the -u user was  specified,
              the command will be executed with the environment of the currently logged in user.

       -o plugin/mail_crypt_private_password=password
              Dovecot option, needed if you use password protected keys


       export [ -U ] | mailbox-mask

       -U     Operate on user keypair only

       Exports  user's or folder's keypair(s) in PEM format.  If the keys are password protected,
       -o is needed.

       generate [ -Rf  [ -U ] | mailbox-mask ]

       -U     Operate on user keypair only

       -R     Re-encrypt all folder keys with current active user key

       -f     Force keypair creation, normally keypair is only created if none found

       Generates new keypair for user or folder. If you want to generate new user key and use  it
       to secure your folder keys, use generate -u username -UR.

       If you want to password-protect your key here, use -o.

       list [ -U ] | mailbox-mask

       -U     Operate on user keypair only

       List all keys for user or folder. No password is required.

       password [ -N | -n password ]  [ -O | -o password ] [ -C ]

       -O     Ask for old password

       -o old-password
              Provide old password

       -N     Ask for new password

       -n new-password
              Provide new password

       -C     Clear (unset/remove) password. Your key will not be protected by password.

       Set, change or clear password from your user key.
