Dual EC DRBG

Dual EC DRBG (Dual Elliptic Curve Deterministic Random Bit Generator) is a cryptographic random number generator defined in the NIST Special Publication 800-90A. It uses elliptic curve mathematics to produce random outputs. The key features of Dual EC DRBG include: 1. **Deterministic Output**: Like other deterministic random bit generators, given the same initial input (seed), it will always produce the same output.
