I like this module but recently I needed to add PGP keys to the .env file and I had an enormous difficulty to do it by adding the whole key in line and adding \n to simulate a new line.

I am not sure about all the types of certificates and their declaration rules so I did not dare to send a "pull request" but, this modification solved for me.

    function parse (src) {
      var obj = {}    

      // certs
      var store_certs = [];
      var current_cert = '';
      var current_cert_key = '';
      var matching_cert = false;    

      // convert Buffers before splitting into lines and processing
      src.toString().split('\n').forEach(function (line) {
        // line length
        var line_len = line ? line.length : 0;    

        // matching "KEY' and 'VAL' in 'KEY=VAL'
        var keyValueArr = line.match(/^\s*([\w\.\-]+)\s*=\s*(.*)?\s*$/)
        // check if init cert declaration
        if ( /-----BEGIN/g.test(line) ) {
            matching_cert = true;
        }
        //
        if ( matching_cert ) {
            // check if end cert declaration
            if ( /-----END/g.test(line) && line_len > 0 && line.substring(line_len-5, line_len) === '-----' ) {
                current_cert += line + '\n';
                // strore
                store_certs.push({
                    key: current_cert_key,
                    value: current_cert
                });
                current_cert = '';
                current_cert_key = '';
                matching_cert = false;
            } else {
                if ( keyValueArr === null ) {
                    current_cert += line + '\n';
                } else {
                    current_cert_key = keyValueArr[1];
                    var value = keyValueArr[2] ? keyValueArr[2] : '';
                    current_cert += value + '\n';
                }
            }
        } else {
            // matched?
            if ( keyValueArr != null ) {
                var key = keyValueArr[1]
                // default undefined or missing values to empty string
                var value = keyValueArr[2] ? keyValueArr[2] : ''
                // expand newlines in quoted values
                var len = value ? value.length : 0
                if ( len > 0 && value.charAt(0) === '"' && value.charAt(len - 1) === '"' ) {
                    value = value.replace(/\\n/gm, '\n')
                }
                // remove any surrounding quotes and extra spaces
                value = value.replace(/(^['"]|['"]$)/g, '').trim()
                obj[key] = value
            }
        }
      });
      // if stored certs
      if ( store_certs.length > 0 ) {
          store_certs.forEach((item, i, array)=>{
              obj[item.key] = item.value;
          });
      }    

      return obj
    }

In me .env file e.g:

TOKEN_UNSUBSCRIBE=14wcn9tckujru2xirq8k38ulstgv7f9m1zg0te8gj9g
PRIV_KEY=-----BEGIN PGP PRIVATE KEY BLOCK-----
Version: OpenPGP.js v2.5.5

... [omit full certificate content]

-----END PGP PUBLIC KEY BLOCK-----

And I use it normally:

    console.log(process.env.TOKEN_UNSUBSCRIBE) // 14wcn9tckujru2xirq8k38ulstgv7f9m1zg0te8gj9g

    console.log(process.env.PRIV_KEY) // output complete private key

    console.log(process.env.PRIV_KEY) // output complete private key

Uh oh!
