The SHA-1 sun has set. Certificates with a SHA-1 signature are no longer available from UW CA.
UW CA began issuing SHA-2 certificates by default on April 27, 2016. SHA-1 certs can be requested by emailing email@example.com. Requests will usually be granted as long as the validity period of the certificate falls in the ranges below. Since a SHA-1 collision has been demonstrated as of February 2017, we may ask for approval from the the owner of the resources you are accessing before granting the request.
|Year Cert Issued||Validity Period|
|2017||1 year from issue date|
|2018||<= 6 months from issue date|
|2019 (before May 1)||<= 3 months from issue date|
UW CA will not issue SHA-1 certs after May 1, 2019.
