thumbprintList

A list of server certificate thumbprints for the OpenID Connect (OIDC) identity provider's server certificates. Typically this list includes only one entry. However, IAM lets you have up to five thumbprints for an OIDC provider. This lets you maintain multiple thumbprints if the identity provider is rotating certificates.

The server certificate thumbprint is the hex-encoded SHA-1 hash value of the X.509 certificate used by the domain where the OpenID Connect provider makes its keys available. It is always a 40-character string.

You must provide at least one thumbprint when creating an IAM OIDC provider. For example, assume that the OIDC provider is server.example.com and the provider stores its keys at https://keys.server.example.com/openid-connect. In that case, the thumbprint string would be the hex-encoded SHA-1 hash value of the certificate used by https://keys.server.example.com.

For more information about obtaining the OIDC provider thumbprint, see Obtaining the thumbprint for an OpenID Connect provider in the IAM user Guide.
