This tutorial explains how you can manage multiple MySQL servers from one phpMyAdmin installation. For security reasons, communication between phpMyAdmin and any remote MySQL server is using SSL encryption (this is not necessary for a local MySQL server since communication between phpMyAdmin and MySQL is not leaving the server). phpMyAdmin is a free software tool written in PHP, intended to handle the administration of MySQL over the World Wide Web. phpMyAdmin supports a wide range of operations with MySQL.

When you rent a dedicated server nowadays, almost all providers give you FTP backup space for your server on one of the provider's backup systems. This tutorial shows how you can use duplicity and duply to create encrypted backups on the provider's remote backup server over FTP. duply is a duplicity wrapper script that allows us to use duplicity without interaction (i.e., you do not have to type in any passwords).

This article is about how to use the S/MIME encryption function of common e-mail clients to sign and/or encrypt your mails safely. S/MIME uses SSL certificates which you can either create yourself or let a trusted certificate authority (CA) create one for you.

eCryptfs is a POSIX-compliant enterprise-class stacked cryptographic filesystem for Linux. You can use it to encrypt partitions and also directories that don't use a partition of their own, no matter the underlying filesystem, partition type, etc. This tutorial shows how to use eCryptfs to encrypt a directory on Debian Squeeze.

Non esistera' mai un software capace di garantire la privacy al 100% ma qualche passo in questa direzione e' stato fatto negli ultimi anni. Molto meno conosciuto del piu' blasonato TOR, e' un software java molto versatile che consente la navigazione attraverso un network criptato e anonimo (anche a livello multi proxy) attraverso pochi click. Per avere una velocita' accettabile quando si naviga su internet e' bene lasciare funzionare I2P per almeno 12 ore in modo che possa "costruire" un network sufficiente per il suo funzionamento. All'avvio I2P lancia di regola IE, per questo motivo su Linux e' necessario aprire Firefox all'indirizzo .... Il vantagio di I2P rispetto a TOR e' la sua versatilita' perche' puo' essere integrato non solo sul browser ma anche sulle chat, sui client di posta e molti altri programmi.

This tutorial describes how to set up database replication in MySQL using an SSL connection for encryption (to make it impossible for hackers to sniff out passwords and data transferred between the master and slave). MySQL replication allows you to have an exact copy of a database from a master server on another server (slave), and all updates to the database on the master server are immediately replicated to the database on the slave server so that both databases are in sync. This is not a backup policy because an accidentally issued DELETE command will also be carried out on the slave; but replication can help protect against hardware failures.

This document explains how to set up a fully encrypted para-virtualized XEN instance. In this howto, the host system is running Debian Etch, while the guest system to be installed will be using Debian Lenny. If you are concerned about your privacy, you might want to consider using hard disk encryption to protect your valuable private data from spying eyes. Usually, the easiest way would be to use your distribution's installer to set up a fully encrypted system; I think most recent Linux distributions support this. However, when you are using XEN to provide virtualization, there are situations where you might not want to encrypt your whole computer with all guest instances, but instead only encrypt one OS instance. This howto will deal with exactly this situation. It assumes that the XEN host system is already up and running.

AES è uno strumento per la cifratura AES con supporto per loop-AES. aespipe è uno strumento che scrive su standard output una versione cifrata di cioè che legge da standard input. Usa l'algoritmo AES (Rijndael). Può essere usato come filtro, per creare e ripristinare archivi di backup tar/cpio cifrati e per leggere, scrivere e convertire immagini di dischi cifrate in modo compatibile con loop-AES.

FTP is a very insecure protocol because all passwords and all data are transferred in clear text. By using TLS, the whole communication can be encrypted, thus making FTP much more secure. This article explains how to set up ProFTPd with TLS on an Ubuntu 8.10 server.
