Dear Vagrant,

Thank you for your concern. I just tested this briefly:

1. I started tinyca (0.7.5-5) as per your instructions with
   'strace -o tinyca2.log tinyca2'.

2. After having selected the CA to work with, but before having created a
   new key, there are three occurrences of /dev/urandom in the strace log
   file.

3. Next I created a new certificate request with a 1024 bit RSA
   key. Both the request and the key were successfully created. There
   were no additional accesses to /dev/urandom in the strace log file.

Tinyca uses openssl commands for all cryptographic operations, which
uses /dev/urandom to seed its PRNG.

Consequently, I believe that tinyca does not use /dev/urandom in an
unsafe way when generating keys.

Regards

Uli
