A Certificate Signing Request, or CSR, is a message sent from an applicant to a Certificate Authority (CA) in order to apply for a digital identity certificate. When creating an SSL/TLS certificate for a server, the CSR is generated along with a private key. The private key is kept confidential, while the CSR is sent to the CA. The CA verifies the applicant’s information and issues a digital identity certificate.

A Public Key Infrastructure, or PKI, is a set of hardware, software, people, policies, and procedures used to create, manage, distribute, use, store, and revoke digital certificates. PKIs are used to secure online transactions, secure data transfers, and enable secure digital signatures. Apple is a trusted Certificate Authority and has created their own PKI to issue digital identity certificates.

Intermediate Certificate Authority

An Intermediate Certificate Authority, or ICA, is a Certificate Authority that has been delegated by a Root Certificate Authority (CA) to issue digital identity certificates. In the Apple PKI hierarchy, the Root CA is at the top, followed by Intermediate CAs, then end-entity certificates.
