supabase-extract-anon-key

To extract the Supabase anon key from client-side code, scan direct assignments, client initializations, and environment variable patterns like NEXT_PUBLIC_SUPABASE_ANON_KEY. This process identifies the public key needed for security audits and RLS testing.

The Supabase anon key is a public key safe for client-side exposure, whereas the service_role key is sensitive and bypasses security policies. Extracting the anon key helps verify that only the public credential is exposed during security assessments.

Supabase anon key validation works by decoding the key's payload to confirm the 'anon' role and project reference. It also checks for expiration to ensure the key is active and correctly formatted before using it for RLS testing.

Yes, you can find a Supabase API key in Next.js environment variables by scanning common patterns like NEXT_PUBLIC_SUPABASE_ANON_KEY. This identifies keys exposed to the client-side for security verification and Row Level Security testing.

You need the anon key for Supabase RLS testing to simulate client-side access and verify that Row Level Security policies correctly restrict data. Extracting the key confirms only the public credential is used, not the privileged service_role key.
