Microsoft to drop browser support for sites that secure traffic with SHA-1 certificates. The move is part of an Internet-wide plan to rid the Internet of the weaker encryption. Microsoft’s IE and Edge will stop displaying a lock icon for sites signed on a certificate. The lock icon signals that the bits between browser and website are encrypted, and so not vulnerable to spying. Google and Mozilla have also pledged to drop support for certificates on Jan. 1, 2017, but may accelerate that to July 1, 2016.”]
