oidc-thumbprint-finder

Dockerfile that takes in an OIDC IdP URL to obtain its thumbprint (SHA1 hash of the public certificate)

• You MUST include the HTTP protocol as part of the URL (see examples)
• You MUST exclude the trailing slash

Example (using default - GitHub's )

docker run --platform linux/amd64  nullstring/oidc-thumbprint-finder:latest
