One aspect of the present invention provides a method and a system for securing data and transmitting it securely. Data is encrypted on a source computer and transmitted to a receiving computer. Users must provide authentication to access the data on the source or receiving computer. The data is not decrypted on the receiving computer until access to it has been authorized. The data can be viewed on the receiving computer or processed to create a print file. The print file can be printed onto pre-printed or partially pre-printed forms. A second aspect of the present invention provides a method for dividing a data file into portions and encrypting the portions. Not all of the portions are encrypted by the same encryption method. An index file describes the portions into which the data was divided and the methods of encryption used to encrypt the portions. The different encryption methods can use different keys. These keys can be produced by multiplying an encryption key by random numbers.
