Encrypt.exe – a FreeWare / Shareware high level encryption utility

 

 

Useage – Encrypt will only run from a dos command line – go Programs / Accessories / Command Prompt.  Use the cd command to get into the directory where you or the install program have placed the Encrypt.exe file.  If you are encrypting, then make sure that the file to be encrypted is called input.txt and is sitting in the same directory.  If you are de-encrypting, make sure that the file is called output.txt and is sitting in the same directory.

 

To encrypt, type:

 

Encrypt.exe  ENC001255001255001

 

Where 001255001255001 is the key which you are using to encrypt and which your partner will also use to de-encrypt your message.  The 15 digit key is made of 5 x 3 digit components, each of which must have a value >= 001 and <= 255.  therefore the key 023242156082178 is correct but the key 023256156082178 is wrong since the 256 section is out of range.

 

With this type of key, there are 2 to the power of 40 combinations.  If it took a cracker 1/1000th of a second to try each combination then it would take 50 years to try all combinations.

 

This program is freely available globally for download.  It is Freeware to NGO’s, Charities, Human Rights Organisations, personal friends of mine, all persons and organizations in the 3rd world, all journalists globally.  To all others it is Shareware – try it out – if you like it I will set a (very reasonable) price – email me at alexweir@hotmail.com.

 

Of course it is essential that you keep your key(s) totally secret between sender and receiver of message – the best is to personally determine a number of keys while the 2 of you are physically together – and never ever entrust anything to electronic means – keep the keys strictly on paper.  Also never ever use the same key more than once!   And ideally type some random garbage at the start of your message – and always a random and different length of garbage.

 

I do not explain here the technology used to write this program – that will make it more difficult for anyone who sets out to crack messages using this program.  And I have permanently deleted the exact actual code used to write the program. Now if you want a significantly higher level of security than even this program provides, then I can write you and/or your organization a version of this program which is special for you – it will never ever be written again or shared to anyone.  Note that there are 2 to the power 75 versions of this program which could be written.  That is about a million million million million versions.  Such a version will cost you around US$ 5,000-00, and I will come to your company or organization anywhere in the world and create that version in front of you.  That way you will be sure there are NO copies.  And I will leave without a copy of your version and having destroyed the code which comprised your version.  I can even create for you a new version every week or every month.  The advantage of having your special version is that you can even let the key for any message be openly known (though there of course is no real need to do that).

 

This product is not meant to compete with some products which encrypt all your email or even encrypt some or most directories on your hard drive – this is for plain text messages which are important.  Of course you can create those text messages from Microsoft word and re-import to word after de-encryption.

 

The program also handles umlauts, graves, acutes etc from French, German, Spanish, Danish, Norwegian, Swedish  etc..

 

You can download the standard “open” version from http://www.anytimenow.comm/guest - use username <alexweir> and password = <password> (Yes!).  Download ENCunzip.zip ,Encryp2.Cab and EncHelp.htm files into any directory, unzip the ENCunzip.zip and then double click on setup.exe to install… The download is 1.95 megabytes.  Checkout http://www24.brinkster.com/alexweir/Encrypt for any changes of download location and program version.

 

This program does not handle jpg or gif files (for which I see a need among journalists and Human Rights people) – maybe that version will come soon – email and ask me – it will help me to get it done!

 

The program is written in Visual Basic 6.  The install program is in French – please use your intuition if you don’t know that language.
