 necessary parameters are set, by re-creating the blinding parameters.</p>

<p>BN_BLINDING_convert_ex() multiplies <b>n</b> with the blinding factor <b>A</b>. If <b>r</b> is not NULL a copy the inverse blinding factor <b>Ai</b> will be returned in <b>r</b> (this is useful if a <b>RSA</b> object is shared among several threads). BN_BLINDING_invert_ex() multiplies <b>n</b> with the inverse blinding factor <b>Ai</b>. If <b>r</b> is not NULL it will be used as the inverse blinding.</p>
