provisioner-default-password-hash
A map of ssh public keys to install for the root user
This specifies the password hash to use for the install process. This is the root password on CentOS-based installs, the default user on the Debian-based installs, and the root password for ESXi. Any other system that utilizes a SHA512 type hashed password can use this.
To generate a hash, use the following command:
# where "PASSWORD" is the new password to generate the hash for
python3 -c "import crypt; print(crypt.crypt(\"PASSWORD\", crypt.mksalt(crypt.METHOD_SHA512)))"
This will generate a sha512 hash which should work on both operating system types.
