registration authority (RA)
A registration authority (RA) is an authority in a network that verifies user requests for a digital
certificate and tells the certificate authority (CA) to issue
it. RAs are part of a public key infrastructure (PKI), a
networked system that enables companies and users to exchange information and money safely and
securely. The digital certificate contains a public key
that is used to encrypt and decrypt messages and digital
signatures.
