Beware - some versions of HPUX do not come with a suitable random data device. If I recall correctly, HPUX 11.00 and 11.11 do not have one, but HPUX 11.22 does. Your end-users may need to install one of the random data devices available from HP (they freely provide /dev/random, /dev/urandom and their own version of openssl with a bundled random data device) SunOS/Solaris 5.6 and 5.7 also lack a random data device. -- Adam Mlodzinski ______________________________________________________________________ OpenSSL Project http://www.openssl.org User Support Mailing List openssl-users@openssl.org Automated List Manager [EMAIL PROTECTED]
