RainbowPublicKeySpec

protected RainbowPublicKeySpec(java.lang.String oid,
                               int docLength,
                               byte[][] coeffQuadratic,
                               byte[][] coeffSingular,
                               byte[] coeffScalar)

Constructor used by the RainbowKeyFactory. It constructs internal data types out of these bytes got from ASN.1 decoding.

Parameters:

docLength -

coeffQuadratic -

coeffSingular -

coeffScalar -

Method Detail

getAlgorithm

public final java.lang.String getAlgorithm()

Returns:

name of the algorithm - "Rainbow"

getOIDString

public java.lang.String getOIDString()

Returns:

the OID of the algorithm

getDocLength

public int getDocLength()

Returns:

the docLength

getCoeffquadratic

protected short[][] getCoeffquadratic()

Returns:

the coeffquadratic

getCoeffsingular

protected short[][] getCoeffsingular()

Returns:

the coeffsingular

getCoeffscalar

protected short[] getCoeffscalar()

Returns:

the coeffscalar

getOID

protected codec.asn1.ASN1ObjectIdentifier getOID()

Returns:

the OID to encode in the SubjectPublicKeyInfo structure

getKeyData

protected byte[] getKeyData()

Return the keyData to encode in the SubjectPublicKeyInfo structure.

The ASN.1 definition of the key 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
       }
 

Returns:

the keyData to encode in the SubjectPublicKeyInfo structure
