Password Encryption

Encrypting Passwords

To encrypt a password, use the hws-encrypt command:

/$ cd /usr/local/hws-otel-collector/bin
/usr/local/hws-otel-collector/bin$ ./hws-encrypt
Enter the password to encrypt: <type the password>

Using Encrypted Passwords

Once a password has been encrypted, it can be used in a hws-config.yaml configuration file instead of a readable password:

targets:

  - target:
      hostname: myhost-01
      type: storage
    http:
      https: true
      port: 443
      username: myusername
      password: GkwzG6bx8cUhoeQW+/1ERI+2LOyB

The Master Password

On first use, the hws-encrypt command will create the security/hws-keystore.p12 file to store a unique and random master password. This master password is used to encrypt passwords with hws-encrypt, and decrypt them from config/hws-config.yaml.

The hws-keystore.p12 file must not be modified, as this would prevent decryption from working. Any password encrypted with a given hws-keystore.p12 master password must be decrypted with the exact same *hws-encrypt.p12 file.

The hws-keystore.p12 file can be shared across several hosts so a password encrypted on one system can be decrypted on another. Simply copy the hws-keystore.p12 file to the security directory. This will make Hardware Sentry OpenTelemetry Collector able to decrypt the passwords.
