Symmetric Key Data Encryption

Monday, October 15th, 2007

You can use:

  • GPG - for single files
  • TrueCrypt - for entire directories/partitions

TrueCrypt
Home page of this piece of software.

Very easy-to-follow how-to.

The encryption doesn’t use a public key algorithm because the purpose doesn’t require it.

GPG
Basically:

To encrypt myfinancial.info file, type the command:
$ gpg -c myfinancial.info
Output:

Enter passphrase:<YOUR-PASSWORD>
Repeat passphrase:<YOUR-PASSWORD>

This will create a myfinancial.info.gpg file.

To decrypt file use gpg command:
$ gpg myfinancial.info.gpg

N.B.: GPG is mostly used for asymmetric key encryption.

The Best from Coppermine

Friday, July 27th, 2007

Coppermine is a good application but it comes with not that good settings. These are the changes I made from the default.

Width of the table for file display (pixels or %)
> 100% o 700

Max width or height of an intermediate picture/video:

> 700

The content of the main page:

> breadcrumb/catlist/alblist

To resize the photos in a massive manner, this program is marvellous:

The aim is having a very good email system (Gmail is OK for this) with a sound notification for incoming mails(Thunderbird in suitable for this, from version 2).

You can download Thunderbird here.

GMail allows you POP access but before you have to say it you want this opportunities (Settings->Forwarding and POP) .

The way to create a GMail account in Thunderbird is explained here (from GMail help).
