+To encrypting data you have to use the public key from your Hiera (`data-*`) git repository named `eyaml_public_key.pem`
 
-On the puppet server this key can be found at `/etc/puppetlabs/keys/eyaml/public_key.pkcs7.pem`.
+For the lower layers (global, server or data) it is on the Puppet server at [`/etc/puppetlabs/keys/eyaml/public_key.pkcs7.pem`](https://git.psi.ch/linux-infra/bootstrap/-/blob/prod/instcode/puppet/puppet_server/files/crypto/public_key.pkcs7.pem).
 
 Beside this key you also need to have `hiera-eyaml` tool installed on your system.
 
-Assuming the public key is saved in a file (e.g. ``~/eyaml_key.pub``), that the file path has been put into the environment varialbe ``EYAML_PUB_KEY``, then a string can be encripted with::
-
 ```bash
-eyaml encrypt --pkcs7-public-key=$EYAML_PUB_KEY -s secret_string
+eyaml encrypt --pkcs7-public-key=eyaml_public_key.pem -s secret_string
 ```
 
 While a complete file can be encrypted with:
 ```bash
-eyaml encrypt --pkcs7-public-key=$EYAML_PUB_KEY -f secret_file
+eyaml encrypt --pkcs7-public-key=eyaml_public_key.pem -f secret_file
