PKCS12 to PEM

[niyazagtc]

I need to convert pkcs12 to pem. The pkcs12 is in ECC algorithm type.
I am trying with the below code

module.exports = function p12ToPem(p12Buffer, password) {
  if (Buffer.isBuffer(p12Buffer)) {
    p12Buffer = p12Buffer.toString("base64");
  }
  else if (typeof p12Buffer !== "string") {
    throw "p12ToPem only takes strings and buffers.";
  }

  var p12Der = forge.util.decode64(p12Buffer);
  var p12Asn1 = forge.asn1.fromDer(p12Der);
  var p12 = forge.pkcs12.pkcs12FromAsn1(p12Asn1, true, password);
  var keyData = p12.getBags({ bagType: forge.pki.oids.keyBag });
  var certBags = p12.getBags({ bagType: forge.pki.oids.certBag })[forge.pki.oids.certBag];
  console.log('keyData ', keyData);
  console.log('certBags ', certBags);
  var key = forge.pki.privateKeyToPem(keyData);
  return key.replace(/\r\n/g, '\n');
};

The private key is not getting generated, it gives the below error,

Output:

keyData  { '1.2.840.113549.1.12.10.1.1': [] }
certBags  [ { type: '1.2.840.113549.1.12.10.1.3',
    attributes: { friendlyName: [Array], localKeyId: [Array] },
    cert: null,
    asn1:
     { tagClass: 0,
       type: 16,
       constructed: true,
       composed: true,
       value: [Array] } } ]

  var hex = b.toString(16);
              ^

Please advice whats wrong in this.

Unfortunately, we haven't yet implemented ASN.1 parsing for ECC keys, only RSA keys. Forge has an implementation for ed25519 but using only the raw (much simpler) format. PRs are welcome!

Is this the same error?

@bfricka @dlongley still not support ECC keytypes?

is this fixed?
