HPUX 11i have prebuild OpenSSL package (current A.00.09.07i.002/003). Entropy source is documented by HP on: http://h20293.www2.hp.com/portal/swdepot/displayProductInfo.do?productNumber=OPENSSL11I and it depends on HPUX version You use: -hpux11iv1(11.11) - /dev/urandom, /dev/random, /opt/openssl/prngd/prngd but has no /dev/random, /dev/urandom installed by default -hpux11iv2(11.23) - /dev/urandom, /dev/random, /opt/openssl/prngd/prngd has /dev/random, /dev/urandom installed as kernel module by default Best regards, -- Marek Marcola <[EMAIL PROTECTED]> ______________________________________________________________________ OpenSSL Project http://www.openssl.org User Support Mailing List openssl-users@openssl.org Automated List Manager [EMAIL PROTECTED]
