‘Rainmaker – Command Line Pseudo Random Number Generator’
‘Rainmaker is a command line pseudo random number generator designed to work on multiple platforms. Rainmaker can be used produce cryptographically strong non-blocking output in many formats (Base-16, Alphanumeric, Numeric , and Alpha only modes). The can be used be used to create random passwords, session identifiers, as a source of randomness for other application which require random but specifically formatted random data.
Rainmaker uses the encryption algorithm SOSEMANUK along with a random 128-bit session key and 128-bit Initial Vectors to encrypt the entropy pool gathered from /dev/urandom or /dev/random.’
