The "cert" credential provider allows authentication using
|
|
TLS client certificates. A client connects to Vault and uses
|
|
the "login" endpoint to generate a client token.
|
|
|
|
Trusted certificates are configured using the "certs/" endpoint
|
|
by a user with root access. A certificate authority can be trusted,
|
|
which permits all keys signed by it. Alternatively, self-signed
|
|
certificates can be trusted avoiding the need for a CA.
