I'm trying to implement encryption in PDF files ... The PDF spec says to use RC4 to encrypt the data. I've found some data on how to do RC4 (perl & C) but there seems to (potentially) be a legal issue with using it. Anyone know the actual legal status of RC4? Is it patented or anything. Can I legally implement it and sell software using it? I've seen mention of ARC4 (the "Alleged RC4" algorithm) and it seems like mumbo-jumbo to keep folks out of jail or court. Anyone have any pointers to FAQs on this or know what's up? -- Bill Moran Potential Technologies http://www.potentialtech.com
