Using Ghost to Block PGP Encoding

To demonstrate the user hook defined in this example, you need to download PGP Desktop version 9. At the time of this writing, PGP Desktop Professional version 9 can be downloaded from www.pgp.com/downloads/index.html. This download allows for a free 30-day trial, which should be more than enough time to demonstrate the user hook presented in this and the following chapter. Alternately, if you are currently using a free version of PGP (versions 6 through 8), you can use one of the following patterns:

  PGP version 6 pre-encode pattern (for PGP_SDK.dll): 0x81, 0xEC, 0xC8, 0x00, 0x00, 0x00, 0x53, 0x55, 0x8B, 0xAC, 0x24, 0xD8, 0x00, 0x00, 0x00, 0x57, 0xB9, 0x25, 0x00, 0x00, 0x00, 0x33, 0xC0, 0x8D, 0x7C, 0x24, 0x14, 0x6A PGP version 7 pre-encode pattern (for PGPsdk.dll): 0x81, 0xEC, 0xC0, 0x00, 0x00, 0x00, 0x53, 0x55, 0x8B, 0xAC, 0x24, 0xD0, 0x00, 0x00, 0x00, 0x57, 0xB9, 0x23, 0x00, 0x00, 0x00, 0x33, 0xC0, 0x8D, 0x7C, 0x24, 0x18, 0x6A PGP version 8 pre-encode pattern (for PGPsdk.dll): 0x81, 0xEC, 0xC4, 0x00, 0x00, 0x00, 0x53, 0x55, 0x8B, 0xAC, 0x24, 0xD4, 0x00, 0x00, 0x00, 0x57, 0xB9, 0x23, 0x00, 0x00, 0x00, 0x33, 0xC0, 0x8D, 0x7C, 0x24, 0x18, 0x6A
