Secrets encryption

Jan 1, 0001

Definition

Secrets encryption refers to the practice of encrypting sensitive data such as passwords, API keys, and tokens to protect them from unauthorized access. This is crucial in maintaining the confidentiality and integrity of sensitive information, especially when stored in configuration files or transmitted over networks. Proper secrets encryption involves using strong encryption algorithms and secure key management practices to ensure that only authorized entities can decrypt and access the secrets.

Secure Settings Example

apiVersion: v1
kind: Secret
metadata:
  name: my-secret
type: Opaque
data:
  username: $(echo -n 'my-username' | base64)
  password: $(echo -n 'my-password' | base64)

In this Kubernetes example, secrets are stored in a base64-encoded format, ensuring that sensitive data is not exposed in plaintext. Additionally, it’s recommended to enable encryption at rest for Kubernetes secrets using a provider like AWS KMS or Azure Key Vault.

Insecure Settings Example

apiVersion: v1
kind: Secret
metadata:
  name: my-secret
type: Opaque
data:
  username: my-username
  password: my-password

In this insecure example, secrets are stored in plaintext within the configuration file, making them easily accessible to anyone with access to the file. This practice exposes sensitive information and should be avoided.
