Many Helm charts and manifest files within Kubernetes have Base64 encoded strings to obfuscate secrets.

The easiest way to encode and decode values is to use a couple of commands in Linux: –

To encode a clear piece of information to Base64, use the following command: –

echo "clearvalue" | base64
Y2xlYXJ2YWx1ZQo=

echo "Y2xlYXJ2YWx1ZQo=" | base64 --decode
clearvalue
