Let's Encrypt now provides wildcard certificates

Josh Aas, ISRG Executive Director at ISRG, the entity behind Let’s Encrypt the free automated and open Certificate Authority announced that they’re now providing wildcard cerificates. While they had planned to do so starting in February, they had to postpone this feature due problems with their TLS-SNI domain validation that tied up a lot of their developer resources and prevented them from testing the ACME 2.0 protocol required for wildcard certificates.
