com.securityinnovation.jNeo.ntruencrypt.KeyParams

A class to collect information on an encryption parameter set. An instance of this class holds the data for a single parameter set in its public members.
The static function getKeyParams() can be used to retrieve the KeyParams object associated with a particular parameter set (using the OID as an identifier). The returned object is static and should be treated as read-only.

        // Parse the header, recover the key parameters.
        if (keyBlob[0] != tag)
          throw new IllegalArgumentException("key blob tag not recognized");
        KeyParams keyParams = KeyFormatterUtil.parseOID(keyBlob, 1, 3);


        // Make sure the input will be fully consumed
        int headerLen = KeyFormatterUtil.getHeaderEndOffset(keyBlob);
        int packedHLen = BitPack.unpack(keyParams.N, keyParams.q);
        int packedFLen = (keyParams.N + 4) / 5;
