[3] Usually, client software—for example, browsers—include a set of trusted CA certificates. This makes sense, as many users need to trust their client software.
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 was cross-signed) and form the basis of an X.509-based ...
