Some information about cryptographically secure pseudorandom number generators
http://en.wikipedia.org/wiki/Cryptographically_secure_pseudorandom_number_generator
there are some references to known standards, we can implement one of them to replace random generator from predefined library.
Note:
See TracTickets
for help on using tickets.
As one of approach - use MD5 of Ada.Numerics.Discrete_Random.
In addition we could provide API to register user's random generator.
