Erase and Destroy Any WindowsTM File Definitively Using Low Level Overwrite and Standard Procedures
A new product from LittleLite Software, the security tools software house, permits secure deletion (shredding) of file and folders.
(PRWEB, FPR) -- January 13, 2005 -- LittleLite Software has just released a new security tool: NSHred. With NShred you can eliminate confidential information and data from PC drives. Name, size, contents of erased file or folder can never be recovered, by any software or hardware means. When erasing data, you can apply standard security procedures, such as:
* US Department of Defense DOD 5220.22-M (5 overwrites )
* Gutmann (32 overwrites)
* Complex (3 overwrites)
* Zero out (1 overwrite)
Why just deleting is not enough?
When you delete a file or a folder in Windows(TM) it is not actually erased. Simply, the hard disk descriptor table is updated and the file entry is removed. So, the actual bytes of the file remain on the disk. Even when the file area is overwritten, it is still possibile to recover data, by applying certain laboratory procedures since it's rare that a portion of the hard disk is rewritten more than 5/10 times. It has been calculated that information is completely unrecoverable only after more than 30 rewrites.
How can NShred effectively destroy any data?
NShred detects the file area on the hard disk or other drive. This area includes metadata on file, such as name and date. The area is then rewritten 'n' times depending on the procedure. For instance, with DOD algorithm, the file area is rewritten first with "0" bit, then with "1" bit, then with a random byte. After rewriting, the file area is reduced to zero, the file renamed with random characters and finally deleted. This procedure guarantees that not even a single byte from the former file can ever be retrieved.
Why NShred is different from other shredding tools?
While the majority of shredding tools are "brute force" and "operating system agnostic" erasing tools, NShred behaves accordingly to the underlying Operating System (OS), denying the user the possibility to turn it unstable. For instance, if the OS denies a delete operation, NShred will NOT erase the file. The user will be able to erase it later when it is no more locked by the OS.
Plus, NShred is a .NET Framework Smart Client application, which ensure the user with a superior robustness and full compatibility and integration with the latest Microsoft Operating Systems and tools.
NShred is available for evaluation through the best software downloading sites: try a Google search with 'NShred LittleLite'.

Secure your Windows Data with Folder Crypt, the Ultimate, .NET Powered, Encryption Tool
With Folder Crypt you can password protect your files and folders using state-of-the-art encryption techniques.
(PRWEB, FPR) October 30, 2004 -- LittleLite Software has just released version 1.5 of the award winning "Folder Crypt", the tool for the encryption of Windows files and folders.
This tool lets the user 'password protect' the normal browsing functionality of the Windows file-system, placing a severe barrier to personal data intrusion. Based on a true, binary encryption of the Windows file and folder contents, the process of encryption is not reversible.
Folder Crypt adopts the latest industry standard in encryption. User must supply a password or passphrase which is converted into a series of bytes with SHA384 hash algorithm. These bytes are then taken as the key and initialization vector for the encryption method, that can be the old, but solid, Data Encryption Standard (DES or 3DES), or the new American Encryption Standard (also known as Rijndael). Data can be encrypted also with the ARCFour method, compatible with the RC4(TM) algorithm that is one of the most popular encryption algorithms available, proprietary of RSA Security Inc.
While implementing complex encryption methods, Folder Crypt is very easy to use. Fully integrated with MS Windows shell, with just one click it's possible to password protect any Windows folder or set of files. The decryption can be made by right clicking on a locked folder and entering the right password.
The new version comes with full international characters support and a strong password generator. Besides, all encrypted archives can be compressed to save space on disk.
This utility takes full advantage of the new Microsoft Smart Client technology, which guarantees algorithm correctness and an extraordinary robustness.
Folder Crypt is available for evaluation through the best software downloading sites, such as Tucows and CNET download.com.

The new major release of Iside, the message digest computing
tool, is available.
Data integrity checking and
file and folder comparison
is made fast and easy with Iside, through message digest computing
technology.
(PRWEB) August 25, 2004 -- While Internet is achieving a broader
band almost everywhere, more and more applications rely on the
exchange of very large data files. These exchanges demand accuracy
in file transfer and data integrity.
This is true even for the casual PC user, when he downloads very
large files from the Internet using various protocols, such as:
- HTTP
- FTP
- Peer to peer (P2P)
These files may contain software (any package like ZIP or TAR),
music (MP3, WMA), pictures (JPG, PNG, GIF, TIF) videos (MPG, WMV,
AVI) or any other multimedia content. A movie, for instance, can
be a file of more than 4 gigabytes.
Anyway, the file received after downloading can be DIFFERENT
from the one originally selected.
This can happen mainly for two reason:
1. Malicious modifications on
the source site (including viruses, worms, spyware)
2. Bad transfer (due to trasmission
errors)
Data integrity means the opportunity to verify, in a fast way,
that the content downloaded is digitally equal - or, if you prefer,
bit per bit equal - to the one originally selected. Doing so is
easy by confronting the files' message digest.
For instance: suppose you want to download the latest Linux distribution.
On the HTML Download page you will likely find a file like this:
Hash: MD5
ad3d50fe12c0672a7e4d32b466ab6851
XXlinux-Official-Download-CD1.i586.iso
Download the ISO image. Now, before burning a CD you would like
to be sure that you just downloaded the exact ISO image, bit per
bit. And you want to be sure that the file you downloaded is the
proper file and not just one with the same name (but, perhaps,
plenty of viruses and spywares...)
You may accomplish this by using a "message digest computing
tool", that is a software capable of computing the message
digest (also known as HASH CODE) of any file with any standard
known algorithms, such as:
- MD5
- SHA1
- SHA256
- CRC32
- RIPEMD160
Now, Iside is the perfect tool to make hash confrontation between
files. Iside computes a file hash code with almost any standard
hashing function.
Also, it is possible to compare files by using desktop integration:
right click on a file, select Copy and by right clicking on another
file you will discover if they are equal.
Iside, the message digest computing tool, has now reached maturity
with this new major release (v1.3), and it's available for a trial
download at http://www.littlelite.net/iside

LittleLite software
releases the new version of NCrypt TX, the text encryption tool.
NCrypt TX is the solution for the encryption of any text in Windows, especially
for traditional Internet communications, such as e-mails, documents, IRC chat,
messenger chat.
(PRWEB,
PRESS
WORLD, FPR)
April 17, 2004--LittleLite Software
has released version 1.6 of the
award winning "NCrypt TX",
the tool for the secure communication
over the Internet.
NCrypt TX looks like a common text editor but it has the capability to encrypt
any text using the latest, standard encryption techniques. The encrypted text
is composed by a series of hexadecimal numbers and can be viewed with any text
editor, but to decrypt it's necessary to know the encryption password or passphrase
and the encryption algorithm used by the sender.
With NCrypt TX it's very easy to transmit secure text with the traditional
Internet means, such as e-mail, IRC chat, messengers like AOL, MSN, ICQ. The
user just types his text in an open NCrypt TX window and, thanks to the Windows
shell integration, can copy/paste the encrypted text onto the preferred e-mail,
chat, messenger program. User can also drag and drop the text between the two
applications. Of course, it's very important to agree with the receiver the
password and encryption method. These data should be sent over a different
channel (for instance, by phone).
NCrypt TX adopts the latest industry standard in encryption. User must supply
a password or passphrase which is converted into a series of bytes with MD5
hash algorithm. These bytes are then taken as the key and initializatoin vector
for the encryption method, that can be the old Data Encryption Standard (DES
or 3DES), or the new American Encryption Standard (also known as Rijndael).
Encryption takes keys up to 256 bits.
Also, traditional encryption methods are implemented, such as Caesar, Vigenere
and Playfair. Useful for didactic purposes, or for aenigmistics or games.
This utility takes full advantage of the new Microsoft .NET Framework, which
guarantees algorithm correctness and an extraordinary robustness.
NCrypt TX is available for evaluation through the best downloading sites,
such as Sofotex or Soft32.com.
