Hello CentOS list, I have a requirement that I need to use encryption technology to encrypt very large tar file on a daily basis. The tar file is over 250G size and those are data backup. Every night the server generated a 250G data backup and it?s tar?ed into one tarball file. I want to encrypt this big tarball file. So far I have tried two technologies with no success. 1) generating RSA 2048

Hey, guys I've been working on whether libvirt supports encrypted snapshots,Here are my versions of libvirt and qemu [root@xx ~]# libvirtd -V libvirtd (libvirt) 4.5.0 [root@xx ~]# qemu-img -V qemu-img version 2.12.0 (qemu-kvm-ev-2.12.0-33.1.el7_7.4) Copyright (c) 2003-2017 Fabrice Bellard and the QEMU Project developers 1. assign $MYSECRET to libvirt secret using the secret-define and

Hi all, There are some surprises when trying to connect Windows 10 (up to date circa Dec 2016) to Samba (4.5.2) with 'smb encrypt = desired' as a config option. I've made a grid of some of the combinations 'smb encrypt = desired' settings below. The biggest surprise is that if 'smb encrypt = desired' is set globally and in the share, Windows 10 cannot connect at

I am playing around with IAX encryption and have had good success. I read somewhere, that trunked packets are not encrypted. Does anybody know if this means the trunk packets themselves are not encrypted but the voice frames in them are encrypted or does this mean that if you are using trunking then encryption of the voice frames will not occur. I have used Wireshark to sniff the packets and it

Hi， I used 'virsh snapshot-create' create an encrypted external snapshot, when I try to use 'qemu-img check' top file, found no entrance to pass backing-file's secret-id 1、Version centos-release-8.2-2.2004.0.1.el8.x86_64 libvirt.x86_64 6.0.0-17.el8 qemu-kvm.x86_64

I have existing systems with un-encrypted disks. I have tried unsuccessfully to encrypt them using LUKS. Has anyone out there been able to encrypt an existing system (after the fact, so to speak)?

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

Kevin, Firstly, you need to obtain the DES libraries. Then you need to tell the Samba Makefile that you wish to compile in DES encryption services and link with the DES library. Then in the smb.conf file you need to add to the [Globals] section: encrypted passwords = yes Then you need to create a separate smbpasswd file. Please read the documentation in the docs directory of the Samba source

I''m trying to use the full disk encryption under Debian and Xen. Not talking about domU. Talking about dom0 and hypervisor booting off an encrypted disk. When I apt-get install Xen and reboot from an encrypted partition, I can start xen, I can select the dom0 but after booting, it dies (appears to hang) Rebooting the standard kernel is fine. Thanks for any hints Sent from my

I was attempting one way to solve: https://bugzilla.redhat.com/show_bug.cgi?id=1400332 "RFE: virt-builder should support templates with encrypted filesystems" However this approach doesn't really work because templates containing encrypted partitions cannot be compressed, and therefore the guest template would be a multi-gigabyte download. I better approach will likely be to use

Hello Why is it necessary to specify encrypt passwords = no to make Samba server start using solely /etc/passwd? Isn't it possible to tell Samba server that on the way between a client and the server, the passwords sould be encrypted, and after decryption, they will be checked against /etc/passwd and not smbpasswd, tdb or whatever backend?

Hello, I have asked on the postfix mailing list for a solution, how to encrypt incoming emails with public gpg key My original idea was to use a smtpd-milter, which would encrypt all incoming plaintext messages of given user, using the users public gpg key. This way, it would look as if the original sender has sent the message encrypted. Somebody suggested this might be better done in Dovecot,

Hi, I have an application where I want to be able to encrypt large amounts of text before storing them to my DB (MySQL Text field - might be switched to a Blob). I have an idea of how to do this, but was wondering what the general consensus is within the community regarding the issue. I have come across a couple different plug ins/gems (Stringbox, EzCrypto), but am wondering what other people

Hello, I am working on a web system (php) that uses R in the backend, and we need some basic fast encryption/decryption for the underlying mysql database that can be used by both R AND php. It does not need to be top-of-the-line, but just provide some basic level of fast encryption/decryption. Any suggestions? Thank you, Ramiro [[alternative HTML version deleted]]

Hi, I would like to store some sensitive data into my DB using Rails, it has to be encrypted. I''ve tried a lot of methods of encryption, they all work. Fine by now, yet when I try to store the results into my DB (tables are UTF-8, SET NAMES UTF8; is there, server UTF-8, DB Connection UTF-8) -- I can cmd (yeah, Windows..) and enter a UTF-8 record into the table, so that''s not

We need to encrypt files before transferring them to the destination Host for security reasons. Encryption must be strong: IDEA, 3DES or similar. One way would be the integration of PGP into rsync. Is there any PGP integration into rsync available ? Thank?s Clemens
