similar to: Regarding SSHA512 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

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

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

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.

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

Good day! I'm just trying to figure out that my understanding of subject is correct. So, if I want to store passwords in my database encrypted with SSHA512 scheme, my only choice for Authentication mechanism is plaintext?

Hello, First off, thanks in advance for all of your help. Now to my issue: I am setting up my first email server. It will be for just me and a few other people. I am using an Amazon EC2 server running Ubuntu 12.04. My MTA is postfix. As I said, this is my first time setting up an email server, so I am following a guide that Arstechnia has published

Hello, I'm running dovecot 2.0.x on a centos 5.6 machine. This is a new installation, I haven't even opened the firewall to it yet. I was trying to telnet localhost 143 and 110 trying to authenticate a user. I'm getting authentication failure in my maillog but no details. Here's the one line I get in my maillog: May 14 15:33:42 ohio dovecot: pop3-login: Aborted login (auth failed,

Hi! My "no" referred to the fact that I had not read the article before. =D Thanks for linking it - I'm sure it will be very useful.

I'll come back there as soon as things calm down a bit. =) Yours, Jyri -- +358-50-5632104 (24/7) +358-46-8822157 (backup)

Hi all, Is there a way to get dovecot to recognize arbitrary password hash schemes when looking up a password in a database? I originally set up with #default_pass_scheme = MD5, and I would like to migrate to SHA512. Seeing as the scheme is actually stored in the password column along with the password in the format $_<scheme#>_$_<salt>_$_<passwordhash>_, it seems to me that

Neither of dovecot.index files are created (.cache, .log, .thread) - these files are created when I open the folder with IMAP client. When mailbox is not used for long time, the indexing takes very long time. So I'm looking for any solution (preferably with doveadm) to manually reindex folders in background. wt., 3 gru 2019 o 20:23 Aki Tuomi <aki.tuomi at open-xchange.com> napisa?(a):
