Can You _ATTACH_ file next time?
March 23, 2006
sorry i tried to attach, but it did not work. little over 19k encryped old datagrams work to be decrypted, encrypted and compared.

the library (c#) has a wealth of algos and i am converting rc4 and shas since i
need them to go from modula-2 to d. maybe someone else sees the need to convert
some others ...
i use the cryptosys pki lib for the rest i don't have yet and try to attach the
d header.

funny i write that now for the second time, i hope it will end up in the ng

You might be interested in some existing crypto work I've done:
  http://svn.dsource.org/projects/deimos/trunk/etc/crypto/hash/

The library "deimos" never really got off the ground, I think it may be tome to salvage what can be salvaged from deimos and put it somewhere else, perhaps in "Ares", Shaun? If the crypto stuff is unsuitable for any reason let me know and I can re-work it.

Woo Hoo!  Definitely send the crypto stuff to Ares if Sean will have it.  I have a blowfish algorithm that I'm working on - not sure how it stacks up with 'r's version, but a consistent API for all of the crypto algorithms would be great.

encryptString(char|wchar|dchar)
decryptString(char|wchar|dchar)

encryptFile()
decryptFile()

I'm not sure if this 'consistent' API is possible given the differences in the crypto libs, or if it's a good idea at all.

That's a bit past the level of what I've been focusing on, but it's certainly a candidate for eventual inclusion.

Need to cater for non-text data too.

 encryptData(ubyte[])

I think it would be useful to have both standalone functions and filters for IO.  However, I think "standalone functions" may be a bit misleading, as some attention should probably be paid to supporting different encoding schemes and such with the same basic interface.  I don't have a tremendous amount of experience here, but I suppose the .NET API might be one model to consider.  The easiest thing in Ares terms might be to consider this an add-on library, since crypto is probably not so essential that it should be considered a core component.  So interface consistency would be an ultimate goal, but it wouldn't be tied to the core library release schedule.  This would also make it easier to offer this as a standalone library for those who prefer Phobos.  Does this sound reasonable?
