http://libtom.org/ The LibTom Projects en-us http://libtom.org/?page=rss My Magic Coding tom\@libtom.org tom\@libtom.org This release fixes a bug in libtommath's mp_prime_next_prime() function which could result under rare circumstances a non-prime integer to be returned. Users of libtomcrypt are not affected by this issue, however some implementations using mp_prime_next_prime() are highly advised to upgrade. This release also includes a fix to mp_shrink() and adds the required files to compile libtommath from Visual Studio 2005/2008 directly. This release was possible thanks to Steffen Jaeckel! Also note the new release numbers are now "x.y.z" (and no longer only "x.y").

Well... libtom.org has been brought back to life. Most links up there are still broken but will be back soon. There's a lot of stuff to think about. For information libtom is back with new maintainers, more informations will be made available as the website is updated. July 17th 2010 OLPC will be submitting patches shortly that fix a host of random corner cases in things from hashes to RSA. This will get merged in an called "LTC 1.18" to be released sometime soon. Patience my friends. Oct 18th, 2007 Answering a few questions I saw in the LibTom group on google groups (yeah I read it, just don't reply there). DH vanished because nobody used it and it was a pain to support. Adding it back should be easy, you can't test beyond 2048 bits because by default, TFM is configured for 4096 bit integers. See tfm.h for the FP_MAX_SIZE macro. TFM won't build on x86-32 unless you have all of the registers available, which means -fPIC is out of the question. If you want to use it in PIC mode, use -DTFM_NO_ASM to use the slower ISO C macros. The RC4 PRNG XOR's it's output against the buffer you pass to rc4_read(). So if you pass the plaintext buffer as the output buffer it will "encrypt" it. Hope that helps. Tom. Sept 7th, 2007 Been a while. Not much updated on the LT front, mostly busy at work doing my thing. I've started composing piano music a few weeks ago. I'll show off some stuff when it's more mature though. Sorry I haven't been around to support the users, but I've been burned too many times. You're on your own mostly, but don't fret, there are decent folk around the net, just have to ask in the right places. Anyways, I'll be putting my first piano composition online in a bit. It's a little prelude in A minor. My 2nd piece is a baroque march/dance in C major. I've started dabbling on a 3rd piece (Sonata in F major) but it's barely even started. Stay tuned Sept 7th, 2007 Added some last minute changes (hopefully it's all coo), not really much new documentation but some new ECC and XTS functionality. May 12th, 2007
