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 succ...

When trying to enter a share, possibly Samba/Windows tries to create an encrypted connection leading to [1]. If it is not possible to renegotiate encryption, then the unencrypted connection should be used instead (remember that 'smb encryption = desired'). Below is testparm output (for the smb encrypt (no Global, only per share) = desired case): [global] realm = PHYSICS.WISC.EDU server string = %h server workgroup = PHYSICS max log size...

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 n...

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 encryp...

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 distribution. Samba-1.9.17alpha5 was re...

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 i...

...hould 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 the new qcow2 encryption (LUKS-based) recently written by Dan Berrange. I am posting this patch just to record the code changes. Rich.

...n the server side or does it accept either? The native password storage system in NT is the same as the encrypted password system used in SMB (big surprise there!) which means NT doesn't have this problem. It just always says "I want encrypted passwords". Note that the "I want encryption" bit does not exclude the client sending non-encrypted passwords, it just means that they are supported. The client is free to send non-encrypted passwords if it wants to and the server will do the encryption once it arrives. Andrew

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?

...sue. I have come across a couple different plug ins/gems (Stringbox, EzCrypto), but am wondering what other people are using. I like the idea of using Symmetric-key cryptography (and in particular, I would like to be using Twofish), and then probably encrypting the random password and IV for each encryption using a public key scheme. I guess I am wondering what other people''s response to such an approach is, and whether or not there are suggestions for other approaches. My main concern with the approach noted above is how to secure the private key used to encrypt the key and IV used to encr...

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 where the problem is. So after I use the encryp...

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
