Given that Certificate Authorities have already stopped issuing SHA-1 certificates, most likely, you have already addressed the use of SHA-1 certificates for inbound connections by migrating to SHA-2 certificates. In case you have not, this is a reminder for you to do so.
What's Happening with Browsers?
Many browsers (eg, Google Chrome, MS IE) have now published their desupport plans for SHA-1. The timeline for desupport of SHA-1 is dependent on your certificate authority and your browser.
You need to ensure that your inbound connections are using SHA-2 signed PKI certificates. If you do not move to a SHA-2 certificate and the end-user browser requires one, your Oracle E-Business Suite users will receive a warning or error.
