hi, Q1: How to produce a page fault? Q2: How translate physical memory address into virtual memory address? Because phys addr is 64 bit and virtual addr is 32 bit. Q1 description:: I have succeed to add hook in vfs layer to encrypt file data before write and decrypt file data after read. Now, when I use cp command, system will reboot, it seem to caused by encrypt data whose addr is

Hello everybody! I am a Linux admin trying to move my mail system based on qmail to the software which is more spam-protected: exim4 + dovecot-1.0rc15 + pgsql . I've downloaded and rebuild dovecot from src.rpm (for fc4). During the testing stage I've discovered two troubles: 1) the problem with deliver (...I'm not sure it's a really bug). Here is relevant part of my

I have done multiple google searches and searched the mailing list. All of the solutions I found seemed kind of heavy / complicated. I just want a very simple way to encrypt and decrypt a string. Something like: encrypt("fdsfdsfdsf", "some key"); decrypt("fdsfdsfsdf", "some key"); Is this possible? Thanks for your help. -- Posted via

As per Alex's suggestion, attached is the proof of concept "sfile" script. If there is anyone out there with great C skills who can recreate this functionality "out of the box", I think there would be a few happy campers (at least two, anyways). -------- Forwarded Message -------- Subject: Re: Encrypt /decrypta file with ssh keys.

Hi, I have user add/edit forms.While creating a user I tried the following method to encrypt password and stored the encrypted password in the table. def self.sha1(pass) Digest::SHA1.hexdigest("#{salt}--#{pass}--") end But when I try to edit the page I get the encrypted password in the password field instead of the decrypted password. Is there any method to decrypt

The problem ----------- I want to copy a file from machine A (master) to machine B (backup) but I would like to stop root user on machine B to easily look at the file contents. So I encrypt the file to send at machine A and send just the encrypted version to machine B (which has no means to decrypt the file). Then I make a small change in the file in the machine A and want to send the new

Thx for your answer... Why would it define it again? I just want to use this register and add something to it... Cheers

Hi, I need to be able to encrypt files before storing them on S3, and then decrypt them when accessing them. The files will be images, documents, PDF, etc. I am using Carrierwave to handle the file upload and storage. I am storing them in Amazon S3. Has anyone done this, or have any ideas how this would be achieved? Thanks. -- You received this message because you are subscribed to the

Hi all, Does any one know of any encryption/decryption algorithms in R? I'm not looking for anything robust - I want some way of printing output to the screen that the user can't read immediately, but can decrypt a little later. The main thing I don't want to the user to see is a number, so (e.g.) ROT13 isn't appropriate. Hadley -- Assistant Professor / Dobelman Family Junior

Hi everyone, I'm currently working with LLVM on a project about code obfuscation. My goal is to add an encryption "pass" to the back-end in order to obtain an encrypted executable. I've been looking around the linker, especially the "-post-link-opt" option, as I feel the encryption has to be done at the last moment. But I am not experienced with LLVM, nor executable

Hi, I am using dovecot 2.3.16, along with postfix and a PostgreSQL database for managing virtual accounts. I'd like to start using the mail-crypt plugin. However, I'm having a bit some difficulty understanding the documentation at https://doc.dovecot.org/configuration_manual/mail_crypt_plugin to reach my goal. I plan to ask questions about those issues by starting new threads in this

I would definitely get mail-crypt working on your system before worrying about encrypting existing emails. Iirc dovecot should support both types of files (encrypted, and non-encrypted) concurrently. So BEFORE you try anything, make sure via logs, etc that mail is being written to the fs as an encrypted file and that dovecot is able to decrypt it (i.e. you are able to view that particular

The PGO was my first guess but I can get a lot of information. At first, I follow the explanation at http://clang.llvm.org/docs/UsersManual.html#profiling-with-instrumentation but instead of llvm-profdata merge, I used llvm-profdata show *.profraw. Sadly, the information I get is the total number of function, the maximum function count and the maximum internal block count. Do you know if you

Yeah I have already see pintool but I need this to work with ARM and Intel. If I remember correctly, pintool does not work on ARM (or quite bad). My goal with the instrumentation is, once I have the information (time + call), to choose (during a second compilation) if some of my passes are applicable or not.

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]]

Hello, I'm trying to access a samba share using an ADS user credentials. I always get an error, and the debug traces (log level = 5) are giving me the output in the follow. I have searched the samba ML archives, and I have found the thread http://lists.samba.org/archive/samba/2004-April/084545.html but, before asking the system admin to apply the eventual KB fixes, I would like to know if the
