# gen-secrets.sh — generate all bootstrap secrets for the net-kingdom SSO/MFA platform
|
|
#
|
|
# Usage:
|
|
# ./gen-secrets.sh [OUTPUT_DIR]
|
|
#
|
|
# Generates all pre-cluster secrets and writes them to OUTPUT_DIR (default: ./secrets).
|
|
# Output files are structured by component to mirror the KeePassXC entry layout.
|
|
#
|
|
# WARNING: The secrets/ directory must NEVER be committed to git.
|
|
# After entering values into KeePassXC, shred the generated files:
|
|
# find secrets/ -type f -exec shred -u {} \;
|
|
#
|
|
# PI_ENCFILE is NOT generated here — it must be produced inside the privacyIDEA
|
|
# container after deployment:
|
|
# Follow ../k8s/privacyidea/KEY-RECOVERY.md; do not generate missing recovery keys.
|
|
# Extract the resulting file, store it in KeePassXC as a binary attachment on the
|
|
# privacyIDEA/PI_ENCFILE entry, then create the k8s secret from it.
