<p class="MsoNormal"><span style="mso-bookmark:_Hlk92104730">Weaknesses regarding the use of the SHA-1 hash algorithm for signatures have been known for several years. While there is currently a prohibition on the use of CA Private Keys to directly sign OCSP
responses using SHA-1, Private Keys corresponding to OCSP delegated responders may still be used to sign OCSP responses using SHA-1. This ballot establishes a sunset date to prohibit delegated OCSP signing with the SHA-1 hash algorithm.<o:p></o:p></span></p>
