Openpgpjs: Exception Misformed armored text

[rcronald]

When I tried to encrypt a message using a public key (that I copied below in the code), I have the following exception in the browser:
_TypeError: Error encrypting message: Cannot read property 'isPublic' of undefined_

When I debugging the code, to see in which part of the code throw this exception, I found that exception is thrown by the class encoding_armor.js, dearmor method and line 226. The error happens because the last line of the public key is undefined or blank:
if (lineUntrimmed === undefined) { throw new Error('Misformed armored text'); }

I reviewed and validate that the public key has the correct format, but the error persist.

I share my code that I used:

import * as openpgp from 'openpgp'
export class OpenpgpComponent implements OnInit {

privateKey = '-----BEGIN PGP PRIVATE KEY BLOCK-----

Do I have to make any additional settings?

Hi @rcronald! Javascript doesn't allow single-quoted multiline strings, so I'm not sure what code you're actually running, but I suspect the newlines are somehow getting filtered out. Try quoting your string with ` instead. You're also missing a blank line after the Comment: https://openpgpjs.org line.

[confusingbits]

I have this exact same issue. I'm using valid javascript with backtick for multiline quote, so it's not a quote issue.

[twiss]

Hi @confusingbits! Could you post some example code or armor?

[confusingbits]

const pubkey = `-----BEGIN PGP PUBLIC KEY BLOCK-----

  mQINBF0CkssBEADoExELXOoERF5/7Rq7GdJJAEwdvILvCbEqyCXDw5rDo9dA2NZF
  ...
  =HT6x
  -----END PGP PUBLIC KEY BLOCK-----`;
const publicKeys = await openpgp.key.readArmored(pubkey);

Error: Misformed armored text
at _base2.default.decode._webStreamTools2.default.transformPair

This error shows up inside the publicKeys object. It is not thrown. And no keys are added to the key array.
Single quote usage is simply to avoid formating issues in github comments, the real code uses backticks. I get the same issue with private keys or a combination. I'm using keys generated with GPG in mac and it works correctly with other parties.

[twiss]

You can put code between triple backticks to fix the formatting. As is, it looks like you're missing a blank newline after the -----BEGIN PGP PUBLIC KEY BLOCK-----.

[confusingbits]

Blank newline is in the key. I removed it when creating the comment.

I guess the question is what could cause this to fail. Do I need to specify a specific key version or format somewhere so that it parses correctly? I don't know what armored text is, I'm just using the keys that I've been using elsewhere as is. I expected to just be able to paste this in and plug it into this the encrypt function with the text to encrypt. Is there another step that I'm missing?

Fixed the code formatting, thanks for the tip.

[twiss]

You've indented the key, thereby adding leading whitespace. That probably breaks it.

That was the issue, thanks. :)
