Method Detail

• engineGeneratePrivate

  public java.security.PrivateKey engineGeneratePrivate​(java.security.spec.KeySpec keySpec)
                                                 throws java.security.spec.InvalidKeySpecException

  Converts, if possible, a key specification into a BCRainbowPrivateKey. Currently, the following key specifications are supported: RainbowPrivateKeySpec, PKCS8EncodedKeySpec.

  The ASN.1 definition of the key structure is

     RainbowPrivateKey ::= SEQUENCE {
       oid        OBJECT IDENTIFIER         -- OID identifying the algorithm
       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        OCTET
     }
   

  Specified by:

  engineGeneratePrivate in class java.security.KeyFactorySpi

  Parameters:

  keySpec - the key specification

  Returns:

  the Rainbow private key

  Throws:

  java.security.spec.InvalidKeySpecException - if the KeySpec is not supported.

• engineGeneratePublic

  public java.security.PublicKey engineGeneratePublic​(java.security.spec.KeySpec keySpec)
                                               throws java.security.spec.InvalidKeySpecException

  Converts, if possible, a key specification into a BCRainbowPublicKey. Currently, the following key specifications are supported:X509EncodedKeySpec.

  The ASN.1 definition of a public key's structure is

      RainbowPublicKey ::= SEQUENCE {
        oid            OBJECT IDENTIFIER        -- OID identifying the algorithm
        docLength      Integer                  -- length of signable msg
        coeffquadratic SEQUENCE OF OCTET STRING -- quadratic (mixed) coefficients
        coeffsingular  SEQUENCE OF OCTET STRING -- singular coefficients
        coeffscalar       OCTET STRING             -- scalar coefficients
         }
   

  Specified by:

  engineGeneratePublic in class java.security.KeyFactorySpi

  Parameters:

  keySpec - the key specification

  Returns:

  the Rainbow public key

  Throws:

  java.security.spec.InvalidKeySpecException - if the KeySpec is not supported.

• engineGetKeySpec

  public final java.security.spec.KeySpec engineGetKeySpec​(java.security.Key key,
                                                           java.lang.Class keySpec)
                                                    throws java.security.spec.InvalidKeySpecException

  Converts a given key into a key specification, if possible. Currently the following specs are supported:

  • for RainbowPublicKey: X509EncodedKeySpec, RainbowPublicKeySpec
  • for RainbowPrivateKey: PKCS8EncodedKeySpec, RainbowPrivateKeySpec

  Specified by:

  engineGetKeySpec in class java.security.KeyFactorySpi

  Parameters:

  key - the key

  keySpec - the key specification

  Returns:

  the specification of the CMSS key

  Throws:

  java.security.spec.InvalidKeySpecException - if the key type or key specification is not supported.

• engineTranslateKey

  public final java.security.Key engineTranslateKey​(java.security.Key key)
                                             throws java.security.InvalidKeyException
