public class BlockingSecureRandomNIST
extends BlockingSecureRandom
```
Secure random number generator that is blocking after about 6.0 hours on idle devices due to lack of entropy. SecureRandom seeded according to NIST SP800-90A recommendations - SHA1PRNG algorithm - Algorithm seeded with 440 bits of secure random data - Skips first random number of bytes to mitigate against poor implementations Compliance to NIST SP800-90A offers quality assurance against an accepted standard. The aim here is not to offer the most perfect random source, but a source with well defined and understood characteristics, thus enabling selection of the most appropropriate method, given the intented purpose. This implementation supports security strength for NIST SP800-57 Part 1 Revision 5 (informally, generation of cryptographic keys for encryption of sensitive data).
