Why not use entropy only once for the first secret key, then just increment it? Should be faster than xor-ing 256 bits with every try.

Anyone know why some apps shows pubkeys as npub instead of hex?
Only thing I can think of is it helps people better distinguish public from private keys (npub / nsec, vs hex / hex).
Is that it? Or is there more to it

Not bad. Btw check your nonce tag, its missing the difficulty commitment.

Here is an early draft. The code is not yet release-ready, but works and with these steps you should be able to run a PoW Provider.

Not always true, I checked some of the Nostril code. Wanted to add the difficulty commitment, but saw you already did that a few weeks ago. I had been running the Github version without diff commitment, eons behind the jb55 main repo :)

Now that you mention it, I see where it is :)

Thanks for trying it out!
I looked into it and it looks like your client (browser) thinks the preimage for that payment was 0000..0 (all zeroes).
Can I ask what browser and OS you're using? And if you have enabled script-blocking plugins or similar.

Yes, you have to escape the user message before hashing.
Check out https://github.com/nostr-protocol/nips/blob/master/01.md where it talks about how to get event.id
The hash happens on that JSON array, one element of which is the user message. So for the whole array to be valid JSON, the last element (user content) has to have JSON special chars, like quotes or backslashes, escaped.
>---------------
>Are there any gotchas to hashing messages that contain escape characters in the content? I keep getting the wrong hash according to noscl when content contains things like \n or \"

Good idea, will add that to the list. Right now it supports only one relay, but more is better.
Btw you can override which relay it uses by setting the OAK_NOSTR_WS_ENDPOINT env variable. For example:
export OAK_NOSTR_WS_ENDPOINT=ws://localhost:8090

Been playing with that as well, Nostr PoW is awesome. Added a new section just for this in the latest Oak Node.

Or embed some POW in any message where you need to prove you're not a bot or a spammer.
See NIP-13.

Just had a look at the DM NIP-04:
The content is encrypted with "(...) a shared cipher generated by combining the recipient's public-key with the sender's private-key (..)"
That type of encryption is symmetric-key cryptography, meaning both the encryption and decryption happen with the same key. Therefore, both the sender and recipient need to have (derive, generate) the same key.
So one part is deriving the key by both sender and recipient. This is abstracted away in the lines 3-4 of the pseudocode from the NIP [1]. That maybe also explains the '2' in the JS code you asked in another thread.
Anyway, I'd suggest to first play around with a few examples with encrypting and decrypting a message with a aes-256-cbc cypher (AES 256 bits, in CBC mode). That's the "flavor" of encryption asked for in the NIP.
Once you have that, its pretty straightforward to replace let's say the hardcoded test enc/dec key and parameters, with values generated from the user keys.
For inspiration, I linked a few [2] [3] (relatively old, but well reasoned and with Java code samples) articles.
Wall of text, sorry don't mean to overwhelm :) Hope this helps.

As the saying goes, "don't roll your own crypto". Best go with a well-known, well-tested library.
AFAIK all the cryptography you need is in the secp256k1 library. There are implementations (or bindings) for most languages.
For Java, you can have a look at how bitcoinj[1] does it. A perhaps more up-to-date and better maintained project is Sparrow Wallet, which has its crypto bindings in a subproject called drongo[2].

Does NIP-13 PoW also work for PMs?
In the spec it only talks about kind 1 (public note), but reading the NIPs I can't see why it wouldn't work the same for DMs.

If it's you who opened the ticket, I added a comment with a workaround.
You can basically add two dummy env variables to the docker command:
--env OAK_ONION_SOCKS5_HOST=1.2.3.4
--env OAK_ONION_SOCKS5_PORT=1234
and it should work.
Let me know if it works.
