it's been a while since i've played with filesystem encryption so, on centos 5.4 (and other linux distros), is dm-crypt/LUKS considered to be the state of the art WRT encryption? i remember other solutions like loop-aes and others, but what's considered the gold standard these days? rday -- ======================================================================== Robert P.

I have just come to the realization that password encryption using the crypt function in linux, ONLY USES THE FIRST 8 CHARS. I have written routines using crypt allowing 16+ chars, and find that anything past 8 is ignored. Wow. Is there a way around this that can be used in dovecot, as well as encryption routines for an email front end? (not system users). It's the integration with

I am using a FreeBSD 11-2 amd/64 system with dovecot version 2.3.4 installed. I was playing around with different encryption schemes. doveadm pw -l SHA1 SSHA512 BLF-CRYPT PLAIN HMAC-MD5 OTP SHA512 SHA RPA DES-CRYPT CRYPT SSHA MD5-CRYPT SKEY PLAIN-MD4 PLAIN-MD5 SCRAM-SHA-1 LANMAN SHA512-CRYPT CLEAR CLEARTEXT SSHA256 NTLM MD5 PBKDF2 SHA256 CRAM-MD5 PLAIN-TRUNC SHA256-CRYPT SMD5 DIGEST-MD5

Just upgrading to 1.0.0 and I'm trying to switch from PAM (using pam-mysql) to a direct mysql query from dovecot, and I've got both md5crypt and crypt passwords in a password db. http://wiki.dovecot.org/Authentication/PasswordSchemes seems to indicate that I have to pick 1, but that is per auth-worker, right? So, I created 2 auth workers using 2 dovecot-sql config files specifying

Hi, As stated on the Dovecot documentation, at rest encryption is possible [1]. However, these keys are present on the system itself and are unprotected. Therefore, if a system is compromised, the attacker has access to the encrypted mail and the keys. There is no security benefit in that situation, except for hoping that the attacker doesn't understand that this is happening and how.

I am switching from a fedora/postfix/mysql/couriermail/squirrelmail to Centos/.../dovecot/roundcubemail and adding postfixadmin to the mix.

Hello, I have a question about the "mail-crypt-plugin". If each user is having its own mail encryption key, is there a way to encrypt the key with the user password, and to decrypt it when the user logs in? I want to, if this is possible, to prevent any user, even root, to access another user's emails. Thanks, Andr?

Hi, I have a small server at home. I like to put it 'online' and secure it as good as possible. The counterside of putting your personal backups on a server is that it might get hacked... and you don't want have to have your personal docs online... Do you think encryption is needed? How to use encryption with rsync? Thanks in advance, ~D

Hi to all I was looking at protonmail.com Is possible to implement and end-to-end encryption with dovecot, where server-side there is no private key to decrypt messages? If I understood properly, on protonmail the private key is encrypted with user's password, so that only an user is able to decrypt the mailbox. Anything similiar ?

Hai, Do you have advice about Dovecot plugins for mail encryption: https://wiki2.dovecot.org/Plugins/MailCrypt https://0xacab.org/riseuplabs/trees I like NaCL based encryption but the MailCrypt plugin is better because it's maintained by Dovecot developers (is this correct?) Hard to understand MailCrypt docs so may I ask, may I provide per user encryption? I don't like global

Hi Chris, thanks for your answer. It is the first time I decided to encrypt my lvm. I choosed to encrypt the volume group, not every logical volume itself, because in case of doing lvm snapshots in that group they will be encrypted too? And how do I create a new encrypted volume group? Regards Tim Am 6. M?rz 2015 01:58:23 MEZ, schrieb Chris Murphy <lists at colorremedies.com>: >On

What it is way most best for causing bash script run (as root) of time mailbox created (lda_mailbox_autocreate)? I use dovecot 2.3.4.1 in Debian 10.

Hi Railers, I''m looking for something to do asynchronous encryption - where the encryption and decryption keys are different. This is for a scenario where I want to be able to store some information in the database that can only be decrypted in a different physical location using a secret private key (which will not be stored on the machine doing the encrypting). I''m trying

OS: CentOS 5.0 x86. In the past while I was using SL 4.x. I was using BestCrypt. Now in CentOS 5.0, neither BestCrypt nor TrueCrypt seem to work. Is there any volume encryption or full HDD encryption that works with CentOS 5.0 out there (preferably in single-user mode)?

Hi everyone, Was just perusing this article about how trivial it is to decrypt passwords that are stored using most (standard) encryption methods (like MD5), and was wondering - is it possible to use bcrypt with dovecot+postfix+mysql (or posgres)? -- Best regards, Charles
