Hi,

I am experimenting with the C code of the ISAAC pseudo random number generator
(http://burtleburtle.net/bob/rand/isaacafa.html).

Currently the implementation creates (on my embedded linux) 32 bit
hexadecimal output.

>From this I want to create random numbers in the range of [a-Za-z0-9]
*without violating randomness* and (if possible) without throwing 
away bits of the output.

How can I do this mathemtically (in concern of the quality of output) 
correct?

Thank you very much in advance for any help!
Best regards,
mcc
