Drop Secure Professional for Mac

Drop Secure ProTM is an encryption utility that uses multiple encryption ciphers to secure a file in a way that is a little different.Drop Secure ProTM starts by dividing up the file into small chunks. By default, those chunks are 256 bytes long. Each chunk is encrypted with a separate cipher, using a separate password that is derived from a hash of information provided by the user, from the archive, and from the data being encrypted. This password is used only once for that one chunk of data, and then discarded.The chunks of data are placed in an archive file, with pertinent information encrypted again as a group.This increases security over most other encryption utilities. For example - a 1 megabyte file will encrypt four thousand 256 byte chunks of data. Each chunk is encrypted with a different password and one of a range of ciphers. Compare this to a single password and algorithm used by competing products. This version is the first release on CNET Download.com.
