US Patent 9769151 Multi-algorithm key generation and certificate install

Techniques are disclosed for generating multiple key pairs using different algorithms and similarly installing certificates signed using the different algorithms. A customer server receives a selection of algorithms for generating a public/private key pair (e.g., RSA, ECC, DSA, etc.). The customer server generates key pairs for each selection and also generates corresponding certificate signing requests (CSR). The customer server sends the CSRs to a certificate authority (CA). The CA generates certificates associated with algorithm and sends the certificates to the customer server. The customer server may prompt a user to select one or more of the certificates to install, and upon receiving the selection, the customer installs the certificates.
