# Rotate opaque API keys for a self-hosted Supabase installation.
|
|
#
|
|
# Regenerates SUPABASE_PUBLISHABLE_KEY and SUPABASE_SECRET_KEY
|
|
# without touching the asymmetric key pair (JWKS) or JWT tokens.
|
|
#
|
|
# Usage:
|
|
# sh rotate-new-api-keys.sh # Interactive: prints keys, prompts to update .env
|
|
# sh rotate-new-api-keys.sh --update-env # Prints keys and writes them to .env
|
|
# sh rotate-new-api-keys.sh | tee keys # Non-interactive: prints keys only
|
|
#
|
|
# Prerequisites:
|
|
# - .env file (run generate-keys.sh and add-new-auth-keys.sh first)
|
|
# - node (>= 16) or docker
|
|
#
|
