exchangeLR method

void exchangeLR(
  1. dynamic offset,
  2. dynamic mask
)

Implementation

void exchangeLR(offset, mask) {
  var t =
      (((rightShift32(this._lBlock, offset)).toSigned(32) ^ this._rBlock) &
              mask)
          .toSigned(32);
  (this._rBlock = this._rBlock ^ t).toSigned(32);
  this._lBlock = this._lBlock ^ (t << offset).toSigned(32);
}
