"If you have a Mac and need top-notch encryption for your files, you need Drop Secure Professional for Mac OS X. This program uses multiple encryption ciphers to ensure your data is protected.
The program starts by dividing each file into 256-byte chunks, and each chunk is encrypted with a separate password. This password is used only once for that set of data, and then discarded.
The chunks of data are placed in an archive, and pertinent information is encrypted again, as a group. To compromise a single chunk of data, someone with malicious intent would first have to guess the encryption algorithm, then break the encryption using a brute force attack.
Even then, the hacker would have only 1/4000 of your data. Drop Secure Professional for Mac OS X is essential if you have intellectual property, bank statements, attorneys' confidential information, financial records, client data, employee data, contracts, business and marketing plans, corporate information, photographs and videos, police records, government records, end of life private wills, or any other data that needs to be secure.
