Package org.bouncycastle.pqc.crypto.rainbow

## Class RainbowKeyPairGenerator

- java.lang.Object
- - org.bouncycastle.pqc.crypto.rainbow.RainbowKeyPairGenerator

- All Implemented Interfaces:
    `AsymmetricCipherKeyPairGenerator`

      public class RainbowKeyPairGenerator
      extends java.lang.Object
      implements AsymmetricCipherKeyPairGenerator

  This class implements AsymmetricCipherKeyPairGenerator. It is used as a generator for the private and public key of the Rainbow Signature Scheme.

  Detailed information about the key generation is to be found in the paper of Jintai Ding, Dieter Schmidt: Rainbow, a New Multivariable Polynomial Signature Scheme. ACNS 2005: 164-175 (https://dx.doi.org/10.1007/11496137_12)
