Update the isValidClientCertificate() method to consider any
client-supplied intermediate certificates. Previously, in order to trust
client certificates issued by an intermediate CA, users would need to
include that intermediate CA's certificate directly in the client_ca
setting. After this change, only the trusted root CA needs to be set: as
long as the client can supply a set of certificates that chain back to
this trusted root, the client's certificate will validate successfully.
Rework the previous CRL checking logic to now consider CRLs for all
issuers in the verified chains.
Add support for a new token $pomerium.client_cert_fingerprint in the
set_request_headers option. This token will be replaced with the SHA-256
hash of the presented leaf client certificate.
Update OPA to v0.54.0, which changes the JSON serialization behavior for
large integers. Remove the formatting workaround and the unit test that
verified that the workaround was still needed.
Rego will sometimes serialize integers to JSON with a decimal point and
exponent. I don't completely understand this behavior.
Add a workaround to headers.rego to convert the JWT "iat" and "exp"
timestamps to a string and back to an integer. This appears to cause
Rego to serialize these values as plain integers.
Add a unit test to verify this behavior. Also add a unit test that will
fail if the Rego behavior changes, making this workaround unnecessary.
