Now go buy a copy of Applied Cryptography, which answers this and other questions you might have. :)
I know.. I blush. I've become such a netjunkie that not being able to find any of the answers on web pages, or Cypherpunk logs I just panicked. Thank you everyone who sent me a message with the reference. I'd say more, but I have to run and get my fix in. (Btw... what would be the absolute coolest thing folk would like to see added to RSAREF? That is, other than code that we will need to negotiate for. What new thing, speed upgrade, enhancement, etc would just tickle?)

The knowledge that any app I develop using RSAREF can be made into licensed for commercial use product for a set, known, published fee. This would be the biggest win for Consensus. Another really big win would be to add more entry points to the code to legitimize Wei Dai's excellent Crypto++ library, which has to jump in at all sorts of unpublished interfaces.

How about just making all the interfaces at the different levels available. For the next version of SSLeay (when I get it and the documentation finished) will have defined interfaces at the following levels for the various ciphers etc. The actual cipher level eg des_set_key, des_cfb_encrypt, idea_cbc_encrypt... This level is wanted by things like SSL for the fastest on the fly encryption possible. The 'by parts' routines eg EncryptBegin, EncryptUpdate, EncryptFinish (which take a CIPHER pointer as an argument). This is sort of wanted by people implementing higher level digital signature routines but they are usefull in their own right. The 'digital' envelope routines. eg SealBegin, SealUpdate, SealFinish (which take a CIPHER pointer, a MD pointer and the public keys etc. The high level stuff for PKCS-7/S-MIME/PEM etc. I am also documenting the interface to the big number library (anyone want to do DSS :-). -- Eric Young | Signature removed since it was generating AARNet: eay@mincom.oz.au | more followups than the message contents :-)
