I am wrapping up TFM 0.04 this week. Thanks to some code from the NSS folk at Mozilla (which I then further optimized) the code is very fast. If you want an idea check out <a href=http://tfm.libtomcrypt.comfeatures.html>this</a> page and halve the cycle count for the SSE2 core. Once I get the PPC testing finished I’ll update the manual and make a release.
