 You must copy your DS private key (in PEM format) to `pid_mdoc_privkey` file (the password must be defined in `pid_mdoc_privkey_passwd`), and the certificate (in DER format) to `pid_mdoc_cert` file.
 
 You can find example test private DS keys and certificates, for country Utopia (UT) [here](test_tokens/DS-token/) - the password of the example test private DS keys is b"pid-ds-0002".
+To decrypt the private key you can run the following command `openssl ec -in PID-DS-0002.pid-ds-0002.key.pem -out PID-DS-0002-decrypted.key.pem`.
