Registration Authority (RA): Any Legal Entity that is responsible for identification and authentication of subjects

of Certificates, but is not a CA, and hence does not sign or issue Certificates. An RA may assist in the certificate

application process or revocation process or both. When “RA” is used as an adjective to describe a role or function,

it does not necessarily imply a separate body, but can be part of the CA.
