similar to: doveadm pw generates different hash each time it is invoked

I am absolutely dumbfounded by "doveadm pw". My understanding is that the command should be used to create a hashed password that should in turn be placed into /etc/dovecot/passwd Here comes the "dumbfounded" part. I was creating a new virtual user, running doveadm pw to generate the hashed password. But when I tried to login via imap, the password was rejected. So I started

Hi, It may be useful for testing purpose to know if a generated password hash correspond to a given clear password. This can be useful to check if a hash generated by another program can be verified by Dovecot without any errors. This patch adds the ability the verify a password hash using `doveadm pw` via the `-V` option. ??? $ doveadm pw -s SSHA.hex ??? Enter new password: ??? Retype new

Hi, I use Debian jessie with Dovecot 2.2.13-11. While writing a script for Horde to change the passwords in my passwd file I noticed doveadm pw -t fails for SHA512-CRYPT: # doveadm pw -s SHA1 -p test {SHA1}qUqP5cyxm6YcTAhz05Hph5gvu9M= # doveadm pw -t {SHA1}qUqP5cyxm6YcTAhz05Hph5gvu9M= -p test {SHA1}qUqP5cyxm6YcTAhz05Hph5gvu9M= (verified) # doveadm pw -s SHA512-CRYPT -p test

Hello everyone, I'm trying to make dovecot do user authentication against a SQL database. The passwords (managed by Django) are stored as salted SHA1 encoded in hex. I monkey patched Django's password method so that the password hash is made with <password><salt> (Django does <salt><password>, the patched method was verified to return same value as

Hi all, Some time ago, I wrote a small CGI script to let users change their IMAP password. The script runs as www-data user and uses "doveadm pw" to check if a password hash matches a password. Unfortunately, this means that I have to make large parts of my dovecot config world-readable, as otherwise I get errors like this: doveconf: Fatal: Error in configuration file

Hi I would like to simulate dovecot's dovecotpw with a perl script I tried / used use Crypt::SaltedHash; my $csh = Crypt::SaltedHash->new(algorithm => 'SHA-1'); $csh->add($passwd_string); my $salted = $csh->generate; also use Digest::SHA1; use MIME::Base64; $ctx = Digest::SHA1->new; $ctx->add($passwd_string); $ctx->add('salt'); my $salted =

Given the use of random salts, you would have to generate (number of possible salts) rainbow tables. This drastically changes the CPU/storage tradeoffs. >

Hi there, I was wondering if someone could explain how dovecot/dovecotpw produces salt for use in ssha passwords, I'd like to replicate this in PHP so I can write my passwords from php in ssha instead of just sha1. Thanks in advance, Andrea Baitis

dovecot --version => 2.1.7 When I as a normal user the command: doveadm pw -s sha512-crypt -p example_password the command exit with return code 89 and the message doveconf: Fatal: open(/etc/dovecot/dovecot.conf) failed: Permission denied If I make Dovecot's configuration files world readable the error goes away. Please remove configuration file dependencies from "doveadm

The reason it fails is because auth process runs out of memory and there is a bug in libsodium which causes it to crash in this scenario. The fix is to do service auth { ? vsz_limit = 0 # or 2G at least } Aki On 26.09.2018 09:12, Keith Amidon wrote: > I'm using dovecot version 2.3.2.1 (0719df592) and trying to use the > ARGON2ID crypt scheme for authentication using the passdb

OK? So, I have posted on the Centos list, comp.security.ssh, and Linux Forums, and no one seems to have heard of this issue or even have any advice for me. So, I am going to take a shot with the Samba list, since this is related. I have a Centos 6.2 server freshly updated. It is authenticating against an openldap server, and I am having an issue with the hashing algorithms being used by various

I'm using dovecot version 2.3.2.1 (0719df592) and trying to use the ARGON2ID crypt scheme for authentication using the passdb passwd-file driver. My passdb config is very simple: ??? passdb { ????? driver = passwd-file ????? args = username_format=%u <path-to-file-here> ??? } If I generate a password this way: ??? doveadm pw -s ARGON2ID -p 'This is a test' I get a crypt

Hi folks. I've recently set up a Postfix 2.9.6/Dovecot 2.0.19 IMAPS/SMTPS setup on Ubuntu 12.04.2 (Mysql backend). I'm new to all this, so I apologize if this is fairly basic. I've attempted to the best of my ability to search for an answer, but no luck so far. What I'm trying to do is generate a password hash that I can inject directly into my Mysql database (disaster recovery
