Can I use PGPi for commercial purposes?
Yes, you can, but you must obtain a commercial use license from Network Associates Inc. or its authorized representatives. (The GNU Privacy Guard can be used for commercial purposes without any license.) If you are located in the U.S. or Canada, go to: http://www.nai.com/. If you are located elsewhere, go to: http://www.pgpinternational.com/. If you wish to use a PGP-compatible product (i.e., an encryption product that may be interoperable with PGP or based upon the Open-PGP standard, but does not contain software actually owned by PGP to implement its cryptography functions), you may require additional licenses from third parties, such as from Ascom Systec AG in Switzerland if the IDEA algorithm is used in such product or from RSA Data Security, Inc. if the RSA algorithm is used in such product and the product is to be distributed in the United States.
