I do not know about the AES protocol, in specific, but there are a few crypto libraries, most of them available for free at freshmeat and sourceforge, that supply you with several cryptographic protocols (DES, RSA, Blowfish, IDEA, Gost, etc...) and tools. As long as I know, these libraries are available at least for C, C++, Java and Python. Most likely, you can find libraries compatible with most of the existing language. A few of these libraries can be used as statically linked libraries, as dinamically loadable modules and as "components", via CORBA, MS D/COM or KDE DCOP. If this is what you were thinking about, you will find anyone of these open source projects very interesting for you. Have a look at the cryptographic sections of freshmeat.net, sourceforge.net and GNU savannah. > > If this could be done, the system calls could be used by any > software and distributed independent of the Linux kernel, and be > standardized for an inordinate number of uses, no? As long as I know, Loop-AES _is_ usable form any linux software (transparently), _is_ distributed indipendently from the Linux Kernel (you have to compile and install it by yourself, no?) and _can_ be considered a "standard" (as long as the software, no matter which one, does not have to worry about it). > > I am just learning about adding system calls to Linux via > loadable modules, so its why I am asking this question.

For sure, the AES code is quite complex and dealing with it requires a deep understanding of cryptography and programming. (Have a look at the SWIG and SIP tools used to auto-magically transform a standard C/C++ program in a library. You can find SIP at the activestate.com web site. SWIG should have its own web site and/or a project at sourceforge or freshemeat). --------------------- Alessandro Bottoni - Linux-crypto: cryptography in and on the Linux system Archive: http://mail.nl.linux.org/linux-crypto/
