Node.js - crypto.js - PFX header too long

Question

I am trying to load in a PFX and passphrase from a file so that I can make a HTTPS request. Before I start, I already know that the PFX is good and that is not the issue.

I am doing the following:

config.options.pfx = fs.readFileSync('file.pfx');
config.options.passphrase = 'passphrase';

I am passing my options into an agent.

config.options.agent = new https.Agent(options);

I then try to build the rquest where I get the following error:

crypto.js:143
      c.context.loadPKCS12(pfx, passphrase);
            ^
Error: header too long

    at Object.exports.connect (tls.js:1334:27)

    at new ClientRequest (http.js:1416:16)
    at Object.exports.request (https.js:123:10)

I checked this out from a work repository where I know that this works for the original author of it. For some reason my set-up is not running it, though.

Answer 1

I had a similar issue. It turned out I was using fs.readFileSync('file.pfx', 'utf8'), which is correct for PEM files, but since PKCS12 files are binary, you should just pass in fs.readFileSync('file.pfx').

Answer 2

I had the same problem but in my case i was using

pfx: fs.readFileSync('certs/keystore.p12')

In my case, the problem was that the pfx I was using was not correctly generated from the jks. Exporting with keytool was the right solution

keytool -v -importkeystore -srckeystore keystore.jks -destkeystore keystore.p12 -deststoretype PKCS12
