One measure of the strength of an encryption algorithm is its ability to generate cipher text that offers strong resistance to being compressed. File compression algorithms look for redundancies or patterns in the file. The encrypted file should look like random data to a file compression algorithm.

If an encryption algorithm is worth buying then it must demonstrate 0% file compression when trying to be compressed using any of the zip programs now available. PK ZIP, WinZip, and ZipMagic are examples of File Compression programs that are used to compress files.

Dynacrypt cannot be compressed by any of these programs. In fact , the file size will increase if any of the file compression programs are used to try to compress a Dynacrypt encrypted file. This is just another indication of the strength of Dynacrypt and why you should feel secure that your files are well protected from unwanted intruders.
