Class RainbowPrivateKey

java.lang.Object

org.spongycastle.asn1.ASN1Object

org.spongycastle.pqc.asn1.RainbowPrivateKey

All Implemented Interfaces:

ASN1Encodable, Encodable

public class RainbowPrivateKey
extends ASN1Object

Return the key data to encode in the PrivateKeyInfo structure.

The ASN.1 definition of the key structure is

   RainbowPrivateKey ::= SEQUENCE {
         CHOICE
         {
         oid        OBJECT IDENTIFIER         -- OID identifying the algorithm
         version    INTEGER                    -- 0
         }
     A1inv      SEQUENCE OF OCTET STRING  -- inversed matrix of L1
     b1         OCTET STRING              -- translation vector of L1
     A2inv      SEQUENCE OF OCTET STRING  -- inversed matrix of L2
     b2         OCTET STRING              -- translation vector of L2
     vi         OCTET STRING              -- num of elmts in each Set S
     layers     SEQUENCE OF Layer         -- layers of F
   }

   Layer             ::= SEQUENCE OF Poly

   Poly              ::= SEQUENCE {
     alpha      SEQUENCE OF OCTET STRING
     beta       SEQUENCE OF OCTET STRING
     gamma      OCTET STRING
     eta        INTEGER
   }
