Encryption of my scripts

I use a canadian software called ACL to write scripts and want to encrypt them for safety sake in such a manner that they can be used in the encrypted form by my clients.

This depends on what you are actually trying to achieve.

1) You may try to search Google and Wikipedia for topics
dealing with "CODE OBFUSCATION"

if your are trying to keep your script algorithms a secret.

2) If you are more interested with making sure that the script
has not been tampered with, you can scan it with a hash/
checksum generator to create a unique signature,
such as CRC or MD5

3) You can also ZIP the file into a password protected archive,
and/or convert the archive into a self-decrypting EXE file.

4) You can split the script into two parts:

The first script accepts a password and decrypts the
second script into an temporary file, runs that file and
then securely deletes the file by over-writing it multiple
times using special bit pattern, or launching BCWipe
to do it.

You obviously got to consider what happens when your
script is interrupted, to make sure no open data residue
is left behind.

5) Finally, the ACL program itself may have some
facility or plug-in to do what you need, contact the
manufacturer's tech support.

Hope this helps

Need password for encrypted file


Ask the one who did the encryption, because that is the only reason it was encrypted with a password, so nobody else could open it without his / her permission.

Whenever i copy a files from external device lik cd dvd or usb. It automatically turns in encrypted format ie all files r in green colour. Can any1 solve this prob. Pls


You can go to the desktop folder and see if that whole folder is set as encrypted. Right click on the folder and clock properties. Then click the advanced button, and see if the encrypted check box is marked. If it is, see if you can clear the check mark.Try doing the same thing with any individual file that is encrypted. You can format a USB drive with some format other than NTFS. When you copy an encrypted file over to that USB drive, it should force it to be unencrypted, if it is being encrypted by EFS. Otherwise, it was encrypted before it was put on the CD or DVD, and there is nothing you can do except try to get the password used to encrypt it.

You're most likely out of luck. It's encrypted, so you could try a brute force technique. Go to wikipedia and look up "Brute Force"; otherwise, it's next to impossible because of the encryption and the methods currently available to end users.

How to convert menc file to jpg


Apparently the files are encrypted and can be decrypted only on the handset/Mobile unit it was encrypted on.

To prevent getting such file type in the future, follow this procedure
Start>Settings>System Tab>Encryption
UnCheck on encryption and after this you will get only normal (Unencrypted file).

Another way is the activesync way. Transfer the file from the handset to pc via ActiveSync, it will automatically decrypt and paste the regular format on to your PC.

Hope it helps

Password in files


Well if you can save the file but are unsure how to store and keep the file on your pc and have it be safe I would recommend something called Folder Lock. I will provide you a link.

Link: http://www.newsoftwares.net/folderlock/

Summary:
  • On-the-fly 256-bit AES encryption (military standard) for data security.
  • Just as Lockers in physical world, different users can create their own Lockers. A single user can create multiple Lockers with different passwords as well. With Folder Lock, you can choose either to encrypt using 256-bit AES on-the-fly encryption or lock files, folders and drives anywhere on your computer. Each Locker can contain your encrypted files as well as your personal list of locked items.

How I can "Decrypt data files" on Win XP Professional.


Since you reinstalled the OS, the certificate for the user has changed. You can try the following methods, but there is no guaranty it will work.
These method apply only if the computer name and users name stays the same as the original. If the machine name or the users name or the users privilege changed, these method will not work.

Only the following people can decrypt an encrypted file:
· The user who encrypted the file
· Any user who was designated as a recovery agent before the file was encrypted
· Any user who has the public key or private key for the recovery agent or the user who originally encrypted the file
· Any user who has been granted access to the file
Members of the Administrators group cannot decrypt files unless the person who encrypted the files designated them as recovery agents before encrypting the files.

Note You must be the original user who encrypted the file or a designated recovery agent for the file to follow these steps

Method 1:
To remove encryption from a file, follow these steps:
1. Use Windows Explorer to locate the encrypted file that you want to decrypt.
2. Right-click the encrypted file, and then click Properties.
3. On the General tab, click Advanced.
4. Click to clear the Encrypt contents to secure data check box, click OK, and then click OK again.
