The example above uses +os.urandom+, which reflects a cryptographically secure random number generator (CSRNG) provided by the underlying operating system. In the case of an Unix-like operating system such as Linux, it draws from +/dev/urandom+; and in the case of Windows, calls +CryptGenRandom()+. If a suitable randomness source is not found, +NotImplementedError+ will be raised. While the random number generator used here is for demonstration purposes, it is _not_ appropriate for generating production-quality bitcoin keys as it is not implemented with sufficient security. <<ec_math>> uses +os.urandom+, which reflects a cryptographically secure random number generator (CSRNG) provided by the underlying operating system.
