Recently, I have been struggling with many certificates. At present, I know that the longest time is StartSSL The certificate can be signed for 3 years, but some browsers are not secure, such as: Firefox, so gave up.
What is SSL certificate? I don't elaborate here. Alphassl certificate can be signed for one year with high trust. SHA-256 bit. The most important thing is to support pan domain name.
Update on January 9, 2018: add one key to Russia's certificate issuing address: https://assl.space , the issuing steps are similar! Please provide your own translation for Russian If you have fun
