Change the Vault Passwords

Autonomous Identity uses the ansible vault to store passwords in encrypted files, rather than in plaintext. Autonomous Identity stores the vault file at /autoid-config/vault.yml saves the encrypted passwords to /config/.autoid_vault_password. The /config/ mount is internal to the deployer container. The default encryption algorithm used is AES256.

By default, the /autoid-config/vault.yml file uses the following parameters:

$ configuration_service_vault:
  basic_auth_password: Welcome123

openldap_vault:
  openldap_password: Welcome123

cassandra_vault:
  cassandra_password: Welcome123
  cassandra_admin_password: Welcome123

Assume that the vault file is encrypted during the installation. To edit the file:

Change to the /autoid-config/ directory.
```
$ cd ~/autoid-config/
```
First, decrypt the vault file.
```
$ ./deployer.sh decrypt-vault
```
Open a text editor and edit the vault.yml file.
Encrypt the file again.
```
$ ./deployer.sh encrypt-vault
```
