Can't load /root/.rnd into RNG

Try removing or commenting RANDFILE = $ENV::HOME/.rnd line in /etc/ssl/openssl.cnf

The reason: "the -rand" option tells by default to use random file .rnd somewhere in your OS. Since user issues to use .rnd file which does not exist!!!!

Remedy: add -writerand to write the .rnd file if does not exist.

For Example:

root@CentOS:/usr/local/etc/openldap/private # openssl genrsa -rand -genkey -out cert.key 2048
Can't load -genkey into RNG
546983936:error:2406F079:random number generator:RAND_load_file:Cannot open file:/usr/src/crypto/openssl/crypto/rand/randfile.c:98:Filename=-genkey

After adding -writerand

root@CentOS:/usr/local/etc/openldap/private # openssl genrsa -writerand -genkey -out cert.key 2048
Generating RSA private key, 2048 bit long modulus (2 primes)

e is 65537 (0x010001)

I myself will bump into this error again. And ofcourse I will check StackOverflow ( R6000 ha ha ) first!!!
