most secure password scheme
Hello, Thanks for the explanation. So should I go with SSHA512 or SHA512-CRYPT? From your explanation i'm interpreting to mean that SHA512-CRYPT also salts. This is for storing in a mysql database. Also, what should the password field length and type be set for? Currently it's varchar(128) Thanks. Dave. On 4/29/17, Aki Tuomi <aki.tuomi at dovecot.fi> wrote: > >> On April

most secure password scheme
Hello, I have a few questions on password schemes. Is SHA512 the most secure? Is there a difference between SHA512 and SHA512-CRYPT? What about SSHA512 and SSH512-CRYPT? Is there a problem with this sql statement: UPDATE virtual_users SET password=CONCAT(?{SHA256-CRYPT}?, ENCRYPT (?Password Goes Here?, CONCAT(?$5$?, SUBSTRING(SHA(RAND()), -16)))) WHERE user=?user at example.com?; I'm

SSHA512 auth not working
I'm trying to configure SSHA512 passwords and when testing discovered that they were not working as expected. At first i was using Centos 6.4 which doesn't have the glibc CRYPT newest functions ($6$salt$pass) so had to rollback to the Dovecot format ({SSHA512.HEX}saltedpassword+salt ) but I'm unable to let dovecot authenticate properly.

most secure password scheme
I would go with SHA512-CRYPT, since it is compatible with lots of other things. The field length is static and it contains ascii characters, and it appears to be 118 characters long, but it might be a good idea to use varchar(255) nevertheless, in case you decide to use something else someday. With mysql, you can do mysql> SELECT

Directly setting unicodePwd - better type of hash?
Hi, we sync our password from other system by directly setting unicodePwd in samba database file.

Moving or "upgrading" from MD5 to SSHA512
Hello, world! I have a long-running Dovecot & Postfix installation using PostgreSQL back-end. Until now I've been using MD5 hashing but would like to "upgrade" to the salted SSHA512. Is there a way to configure Dovecot so that it would automatically detect the type of the hash stored in the database, so that users who have changed their password (and thus being hashed with

Hi, The args parameter of userdb contains scheme, username format and location of the password file. Please take a look this link https://doc.dovecot.org/configuration_manual/authentication/passwd_file/ For example, mine is: userdb { driver = passwd-file args = username_format=%u /etc/dovecot/imap.passwd } $ head /etc/dovecot/imap.passwd to at localhost.local
