Abstract
In a general aspect, digital certificates are generated. In some aspects, a method includes accessing a primary root certificate of a root certificate authority of a PKI system. The primary root certificate includes a first public key based on a first cryptosystem and a first signature generated with a private key that corresponds to the first public key. A secondary crypto-agile root certificate is generated. The secondary crypto-agile root certificate includes the first public key of the root certificate authority, a second public key of the root certificate authority that is based on a second cryptosystem, a second signature of the root certificate authority that is created with a second private key that corresponds to the second public key, and a third signature of the root certificate authority that is generated with the first private key. The secondary crypto-agile root certificate is propagated to subordinate entities in the PKI system.
