Abstract: Root certificates generated by root certificate authorities may be bound at the time of generation. In an example, a first root certificate can include an identity of a first root certificate authority, a first key identifier associated with a first key of the first root certificate authority and an identity of a first digital signature algorithm used by the first root certificate authority. The first root certificate can also include at least one extension including a second key identifier of a second key associated with the second root certificate authority and an identity of a second digital signature algorithm used by the second root certificate authority, the second digital signature algorithm being different from the first digital signature algorithm.

Abstract: Content, such as an encryption key, may be transmitted between computing systems that both use more than one encryption algorithm. Secrets may be used to encode the content. The different encryption algorithms may be used to separately encrypt the encoded content and the secrets prior to communicating the encrypted, encoded content and encrypted secrets between computing systems.

Abstract: A configuration information management system is provided for secure update of dynamic configuration data in a containerized execution environment. A configuration container may be maintained within the environment separately from an application container hosting a secure enterprise application. The secure enterprise application may require secure configuration information for interaction via a secured connection with one or more remote endpoints from within the application container. The configuration container hosts a service that is configured to maintain the secure configuration information on behalf of the secure enterprise application, allowing the secure enterprise application to not persist secure configuration information within the application container.

Abstract: Methods and systems for cross-certification to bind together two cryptographic systems are disclosed. One method includes receiving, from a first certificate authority at a second certificate authority, a cross certificate request, the cross certificate request including an attribute unique to the first certificate authority. The method includes generating a cross certificate and embedding the hash value as a certificate extension within the cross certificate.

Abstract: Methods and systems for cross-certification to bind together two cryptographic systems are disclosed. One method includes receiving, from a first certificate authority at a second certificate authority, a cross certificate request, the cross certificate request including an attribute unique to the first certificate authority. The method also includes calculating a signature at the second certificate authority based at least in part on the attribute, and calculating a hash value based on a combination of the signature calculated at the second certificate authority and a key associated with the second certificate authority. The method includes generating a cross certificate and embedding the hash value as a certificate extension within the cross certificate.
