print "$ age-keygen -o ~/.age/key.txt"
print "$ export SOPS_AGE_KEY_FILE=~/.age/key.txt"
print "$ export SOPS_AGE_RECIPIENTS=age1..."

# Simular archivo de secretos

print "$ sops -e -i secrets.yaml"

print "\n❌ Problemas con SOPS/Age:"
print "   - Setup manual complejo"
print "   - Gestión de claves manual"
print "   - Sin rotación automática"
print "   - Sin audit logs"
print "   - Colaboración difícil"
print "   - Sin compliance empresarial"
