Actually, I have found it to wedge when using it in conjunction with openssl. Here again are the steps to reproduce the bug. The same can be done in OpenBSD BTW. I tried it with 3 different 1401 cards. * Login with an non accelerated ssh session (e.g. blowfish as the cipher) * Make a file called big. dd if=/dev/urandom of=big bs=1024k count=768 * In another session, login with using 3des (ie. one that will get offloaded to the Hifn card * In the blowfish session, start an encryption process, pipe it through ssh to dump to another machine e.g /usr/bin/openssl enc -des3 -in big -k passphrase | ssh -c 3des [email protected] "cat - > /home/mdtancsa/targetfile.enc" At random periods, the process will get "stuck" * In the 3des session, just hit the enter key. The ssl | ssh commands will become "unstuck." Basically, you just need to do something else that touches the crypto card. e.g. If you are on the console, head /dev/urandom | openssl 3des -out /dev/null -k pass will do the trick.
