Purpose of Ballot
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.

The following motion has been proposed by Corey Bonnell of DigiCert and endorsed by Ben Wilson of Mozilla and Bruce Morton of Entrust.
Motion Begins
This ballot modifies the "Baseline Requirements for the Issuance and Management of Publicly-Trusted Certificates" ("Baseline Requirements"), based on Version 1.8.0:
