Cypherpunks, I see some people thinking about encryption API's and related code. I suggest interested parties take a look at Pr0duct Cypher's PGP Tools and RSAREF. PGP Tools is based on PGP 2.3a, and provides a library of routines upon which applications can be built (magic money for example). RSAREF provides 15 or 18 routines which provide various services, such as encryption, key generation, digital signatures, hashes, etc. I'm not saying necessarily use RSAREF due to licensing restrictions, but take a look at it's overall design. And there is other code available at ripem.msu.edu for example. I know there is a tendency/desire to support PGP, but I think anybody who wants to create a PGP DLL/library version will have to be part of the PGP development team, since PGP is a fairly fast moving target. I don't know what is in store for PGP's future, but future enhancements will probably include PEM support (or whatever standard becomes popular), a new format for keyrings, an API, larger key sizes, etc. I mean, by the time you "update" the current version of PGP to a DLL/library version, a new version will appear which may be very different. I guess what I'm saying is either roll your own encryption, join the PGP development team, or wait patiently.
