PBKDF2 password hashing as in ASP.NET Core
Thank you for your reply.
It's not that simple, though. Just because some core algorithms are
standardised and should be compatible doesn't mean their use in
different implementations leads to interoperable data. The key point
here seems to be that Dovecot just supports SHA-1 with PBKDF2, not
SHA-256. So I'm out of luck here. The different formats are no longer
relevant then.

PBKDF2 password hashing as in ASP.NET Core
Hello,
I'm setting up a new server and, again, seek for a decently secure (from
a security specialist's POV) way to store and verify user passwords in a
database. Additionally now, GDPR requires me to use a solid
state-of-the-art solution.
My OS is Ubuntu 20.04, Dovecot version 2.3.7, database backend with
PostgreSQL 12.
Obviously, storing the plaintext password is a terrible idea.

argonid and dovecote
on a FreeBSD 11.2 amd64 machine, I am trying to get Dovecot 2.3.4 to play
nice with "argonid" encryption.
In the "10-auth.conf" file, I tried:
auth_mechanisms = plain argon2id
Upon restarting dovecot, I received an error message when attempting to
actually it:
auth: FATAL: Unknown authentication mechanism "ARGON2ID"
Output from doveadm pw -l

Time for key stretching in encrypted private keys?
In 0.9.7 the private key encryption was switched from 3DES to AES,
(https://bugzilla.mindrot.org/show_bug.cgi?id=1550) the motivation for this
being that 128-bits of security is better than the 112 or so you get from
3DES these days. Interestingly that bug is about upgrading to AES-256, but
we ended up with AES-128. Presumably due to the Solaris crippling?
However ssh-keygen still uses a

Location of match?
Is it possible with Ferret to find the location of the matches in a
document? For example imagine I have 100 documents and I search with
the phrase "bob~0.5" and that returns 3 matching documents. How can I
then find all locations in a specific document where it matched
"bob~0.5". What I need is something like an array that contains the
start index and length for each

Rails 3 app has strange behaviour with Mysql2 database
Hi,
I have developed a little web app with a sqlite3 database in
development environment. Now I switched over to mysql2 for production
environment. At a first look everthing looks good!
BUT, I have delayed_jobs that run methods in the background, where two
nested active records were compared with "if hash1 == hash2", then it
should just show whether they are the same or not. With

PBKDF2 password hashing as in ASP.NET Core
In case you are interested,
https://wiki.dovecot.org/HowTo/ConvertPasswordSchemes
By the way, I am bit sceptical that CRYPT-SHA512 is less secure than PBKDF2.
CRYPT-SHA512 is not "just" SHA512(salt||password), it does at least 1000 rounds of hashing in similar way as PBKDF2 does. So, what is your reasoning for claiming that PBKDF2 is much secure than CRYPT-SHA512?
Also, if you look

Can Auth dict proxy protocol be used to validate a password?
I'm interested in using authentication via a UNIX socket as documented at http://wiki2.dovecot.org/AuthDatabase/Dict.
(We are currently using a checkpassword script to enable us to authenticate against a django app that stores passwords in pbkdf2 format, but I'm concerned about scalability as we grow - specifically the comment about performance on

[PATCH] New commands to list devices by UUID and label
This isn't very well tested at the moment because my main testing
machine is broken. So just for comment, only to be applied with
caution.
This patch has two new commands which make it much easier to look up
filesystems by their UUID or label. They are:
list-devices-by-uuid
list-devices-by-label
Each returns a hashtable (or whatever the equivalent structure is in

/dev/md1 => 93% Used. Warning. Disk Filling up. - what would be safe to delete in /boot ?
Hello CentOS users,
in the recent time I keep getting the logwatch warnings from my 2 dedicated
servers running CentOS 7.4.1708.
I guess because of the numerous kernel updates (because of
Spectre+Meltdown) in the near past?
Could someone please suggest me, which files in my /boot partition would be
safe to delete?
I would like to avoid the situation of having to boot the rescue partiton
etc.
