Multiple File Encryption Software for WindowsDr Aiko Pras, of the University of Twente's Design and Analysis of Communication Systems group, said on May 29, 2013: "[An] interesting development is the cloud: everyone stores all sorts of documents there, but no-one considers that all these files eventually end up in the United States. You can depend on it that the American authorities [NSA] — and soon the Chinese — will be reading them."
"Microsoft has collaborated closely with US intelligence services to allow users' communications to be intercepted, including helping the National Security Agency to circumvent the company's own encryption, according to top-secret documents obtained by the Guardian. ... The documents show that the company worked with the FBI this year to allow the NSA easier access via Prism to its cloud storage service SkyDrive, which now has more than 250 million users worldwide."
So if you store confidential data in the cloud then it's highly advisable to encrypt it before uploading.
Cryptosystem ME6 is intended for encryption and decryption of single files or multiple files on PCs, for secure storage or secure transmission. It uses a 500-bit key for security, and has features designed to minimize the chances of user error. Here is a screenshot:

A summary of the features of Cryptosystem ME6:
- ME6 is a Windows program with an efficient user interface.
- It uses a secure symmetric key encryption algorithm (based upon the irreversibility of the MD5 message digest algorithm).
- Has built-in help; right-click on a command button displays the appropriate help.
- User can encrypt/decrypt a single file or act on multiple files in a single operation (batch mode).
- Ability to include subfolders in an operation (this includes all subfolders of subfolders).
- Ability to produce output files with names the same as, or different from, the input files.
- Use of long key phrases (up to 64 characters).
- Production of 64-byte random keys (saved as keyfiles).
- Ability to save the setup for the next run, or to save as an "operation file" for later use.
- A way to test the randomness of bytes in any file, with a graphical display of randomness in individual files.
- The purging of the plaintext file when the file produced by encryption has the same name as the input file.
- A reliability test to demonstrate that the result of encryption-and-decryption produces the original input file.
- Extensive error-checking (e.g., whether there is sufficient disk space for output files) and informative error messages.
- Information is given on the main screen concerning specified files (e.g., whether they appear to be encrypted).
- Encrypts/decrypts files on a floppy disk even if the disk is nearly full.
- Prevents accidental encryption of exe, dll and other files necessary for proper operation of your Windows PC.
- Checks for certain operations on certain file extensions such as doc and if the operation involves the deletion of such a file ME6 warns that antivirus software may be activated, and advises what to do if so.
- Encrypted files can be sent to another person who can (if they know the encryption key) decrypt them using the ME6 demo program (without the need to purchase a user license).

In January 1999, the Defense Research and Development Organization (DRDO) [of India] issued a 'red alert' against all network security software developed in the US. ... Specifically, the DRDO is concerned about U.S. "encryption software products" that can be 'broken' by the NSA. The agency pointed out "no encryption software products can be exported from the U.S. if they are too strong to be broken by the U.S. National Security Agency." ... The letter says: "To put it bluntly, only insecure software can be exported. When various multinational companies go around peddling 'secure communication software' products to gullible Indian customers, they conveniently neglect to mention this aspect of the U.S. export law." — Cryptography and Liberty 1999: An International Survey of Encryption Policy
Cryptosystem ME6 was designed and developed in Europe. Thus it was not designed (as most commercial U.S.-developed encryption software is) to be sufficiently weak to qualify for a U.S. export license. On the contrary, it was designed to be as strong as possible.
This file encryption software has no backdoor. The encryption key is not hidden in the ciphertext. (The encryption algorithm is explained in detail in Chapter 2 of the User Manual.)
