Most browsers, smartphones and servers in use nowadays support SHA-256 SSL certificates. If your company makes use of older computers, you may encounter compatibility problems when switching to SHA-256 certificates.

Kinamo recommends you always order the SHA-256 version of a certificate. Should any problem arise, the certificate can be re-issued with an SHA-1 signature free of charge.

The importance of migrating to SHA-2356 certificated is detailed in the SHA-1, SHA-2 en SHA-256 page.
