certSIGN: CPS specifies md5 and sha1WithRSAEncryption as useable signature types

RESOLVED FIXED certSIGN
AI Summary

The certSIGN Certification Practice Statement (CPS) originally included md5 and sha1WithRSAEncryption as acceptable signature algorithms. This raised concerns due to the known weaknesses of these algorithms. Following a report, certSIGN confirmed that no certificates had been issued using these algorithms and took immediate steps to update the CPS. The problematic algorithms were removed in the updated CPS version 1.33, which was published on July 8, 2021.
