Unable to get PEM using KEYUTIL.getPEM.

[trusktr]

This is my code:

var rsa = require("jsrsasign");
var keypair = rsa.KEYUTIL.generateKeypair("RSA", 256);
console.log(keypair.prvKeyObj);
console.log(rsa.KEYUTIL.getPEM(keypair.prvKeyObj)); // ERROR

It results in this error:

Uncaught unsupported object nor format

keypair.prvKeyObj is a RSAKey object, and I believe that is what the rsa.KEYUTIL.getPEM method accepts basedon the docs. Why might I be getting this error?

I had the same issue. After struggling with it for an hour or so I found that one requirement in KEYUTIL's code was not being satisfied: keyObjOrHex.isPublic == true. By printing the prvKeyObj you can see it doesn't have that attribute at all. I added it manually as a workaround and it seems to work:

var keyPair = r.KEYUTIL.generateKeypair("RSA", "512");
keyPair.prvKeyObj.isPrivate = true;
var privateKey = r.KEYUTIL.getPEM(keyPair.prvKeyObj, "PKCS1PRV");

Not sure if it's a bug in generateKeypair or what, but man that was annoying to find.

I've fixed it today on version 4.2.3. Thanks.

I think this is back in 4.7.1-all-min

var kp = KEYUTIL.generateKeypair("RSA", 1024);
<< undefined
kp
<<Object {prvKeyObj: RSAKey, pubKeyObj: RSAKey}
KEYUTIL.getPEM(kp.prvKeyObj, "PKCS1PRV")
