@NotMutable @ThreadSafety(level=COMPLETELY_THREADSAFE) public final class RSAPrivateKey extends DecodedPrivateKey
This class provides a data structure for representing the information contained in an RSA private key. As per RFC 8017 section A.1.2, an RSA private key is identified by OID 1.2.840.113549.1.1.1 and the value is encoded as follows: 
   RSAPrivateKey ::= SEQUENCE {
       version           Version,
       modulus           INTEGER,  -- n
       publicExponent    INTEGER,  -- e
       privateExponent   INTEGER,  -- d
       prime1            INTEGER,  -- p
       prime2            INTEGER,  -- q
       exponent1         INTEGER,  -- d mod (p-1)
       exponent2         INTEGER,  -- d mod (q-1)
       coefficient       INTEGER,  -- (inverse of q) mod p
       otherPrimeInfos   OtherPrimeInfos OPTIONAL
   }

   OtherPrimeInfos ::= SEQUENCE SIZE(1..MAX) OF OtherPrimeInfo

   OtherPrimeInfo ::= SEQUENCE {
       prime             INTEGER,  -- ri
       exponent          INTEGER,  -- di
       coefficient       INTEGER   -- ti
   }
