The PDF format is much more handy, and also more powerful, as PDF files are searchable and may contain hyperlinks. The Acrobat Distiller , one of the tools coming with Adobe Acrobat , allows you to convert postscript files to PDF format. Clicking on the icon gets you to an anonymous ftp site for download.

Although this is rarely the case in academia, sometimes there arises the need for encrypting stuff that one sends through the Internet.
Encryption is just another facet of data compression .
The optimally compressed data file must look from the outside like uncorrelated white noise. The entire information is in the key. Hence, zipping the file with setting a password usually provides sufficient protection. However, if there arises need for more protection, it may make sense to encrypt the already zipped file once more using the Norton Secret Stuff encoder while setting a second password. The tool is a freebee.
