About
jwksfetch is a single Native AOT executable (no .NET runtime required) that retrieves a public
JSON Web Key from a remote JWKS endpoint or via OIDC discovery, then emits the key in PEM format
to stdout. Designed as a companion to jwtdecode: pipe jwksfetch output directly into
jwtdecode --verify --key-file - for end-to-end offline JWT verification after an initial key fetch.

Copy a command tailored to that specific architecture, type, and scope - useful when winget would otherwise pick a different default.
Security
No known CVEs for JwksFetch.
Coverage is best-effort and depends on a winget package mapping to an NVD CPE entry. Absence here is not a guarantee of safety.
