We have just updated our AlwaysOnSSL API. The API now supports the synchronous ordering of TLS certificates with up to 2048-bit RSA, 4096-bit RSA and ECC (previously only 2048-bit RSA).
Despite numerous changes on the part of the Certification Authority, as a customer of CertCenter AG you do not have to make any adjustments to your existing connection to the CertCenter API. Your existing mod_fauth integration will also remain compatible.
For the generation of certificates with larger RSA keys or ECC only a CSR generated accordingly is necessary (with 4096-bit RSA or ECC key). The CertCenter API then intelligently interprets the rest and does the work for you in the background.
