Creating an encrupted password for kickstart - CentOS

Use OpenSSL to generate an MD5 crypt:

# openssl passwd -1 "password here"
$1$e/5d7DEs$bhFiuOQp8MMe785dzvBPv.

Use grub-crypt to generate a SHA256 crypt:

# grub-crypt --sha-256
Password:
Retype password:
$5$W/DyB05xk2UIZz6k$YyBl36yKHVmaFmJHNS1m/b2/viRa6KnQe3dDQVZZ5n3

Put the password hash in your kickstart file:

rootpw --iscrypted password_hash

Make sure your authconfig configuration matches the crypt:

authconfig --enableshadow [--enablemd5|--passalgo=sha256]
