The role of root certificate as in the chain of trust. In cryptography and computer security, a root certificate is a public key certificate that identifies a root certificate authority (CA). [1] Root certificates are self-signed (and it is possible for a certificate to have multiple trust paths, say if the certificate was issued by a root that ...
Certificate authority. In cryptography, a certificate authority or certification authority (CA) is an entity that stores, signs, and issues digital certificates.
