Ansible Vault Secret

shAnsible Vault can encrypt a file which includes sensitive data. However, we may be able to decrypt the file with password or by cracking hash to retrieve password.

Decryption

First check the file encrypted with Ansible Vault.

cat example.yml

# -- output --
$ANSIBLE_VAULT;1.1;AES256
62313365396662343061393464336163383764373764613633653634306231386433626436623361

We can use ansible2john to generate the hash to make it crackable.

ansible2john example.yml > hash.txt

Then crack this hash using John The Ripper or Hashcat.

john --wordlist=wordlist.txt hash.txt
# or
hashcat -a 0 -m 16900 hash.txt wordlist.txt

After cracking and retrieving the passwrod, we can use it to decrypt the file as below.

ansible-vault decrypt example.yml --output decrypted.txt
