Cannot decrypt file stream - readMessage(): Error: Misformed armored text

Node.js: v16.20.2

I'm trying to decrypt a file but the readMessage() fails reading a encrypted file stream Error: Misformed armored text .
It works to encrypt a stream and immediately decrypt it, as shown at this example, but if it has to be stored and then decrypted it doesn't work.

Error: Misformed armored text
    at /Users/username/my-project/node_modules/openpgp/src/encoding/armor.js:253:25
    at processTicksAndRejections (node:internal/process/task_queues:96:5)

How can we make it works to decrypt from an encrypted file stream?

I created a code sample which you can run to test this issue: https://github.com/jeff-pal/openpgp-debug/blob/main/src/index.ts

See #1305 (comment) .

Okay, so just to clarify the root cause of this issue in order to help other understanding this let me share my conclusion. According to the message format expected in readMessage it must be Stream<string> format if it's a stream.

export function readMessage<T extends MaybeStream<string>>(options: { armoredMessage: T, config?: PartialConfig }): Promise<Message<T>>;
export type MaybeStream<T extends Data> = T | Stream<T>;

make sense?

thanks @larabr !

If you're passing an armoredMessage it must be a string or Stream<string>; if you're passing a binaryMessage it must be a Uint8Array or Stream<Uint8Array> :)
