Electron Cash fails with "non-canonical DER signature"

[elebit]

Sorry for cluttering the Electrum forum with an Electron Cash question, but I was hoping someone who had used it could chime in. Is there an official forum somewhere?

I wanted to split a little bit of BTC into BCH. The first attempt using Electron Cash was successful. The second was not, and resulted in a transaction the server did not accept ("non-canonical DER signature").

Has anyone encountered this problem and knows what the cause might be?

One difference is that the first transaction spent a p2pkh uxto and the second one spent a p2pk. Has anyone spent a pay-to-public-key uxto with Electron Cash and did it work?

It won't work, because electron cash was not built from scratch,it's only modified for normal BCH transactions. That's why p2pk and multisig transactions are not working on electron because it does not supports BCH properly and transaction is getting denied by server because it might be using bitcoin blockheader but broadcasting it on bitcoin cash server or vice versa.

there is no "p2pk" as far as i know. there is just P2PKH which means "Pay To Pub Key Hash" which is the usual key pairs which need 1 signature (the address begins with 1).

the other thing is "p2sh" which is "Pay To Script Hash" which is those multi signatures.

and electron cash does not exactly support multisig for the time being: https://github.com/fyookball/electrum/blob/bcc19c6e2c5e37a462bd953adb1187b2b69700b1/RELEASE-NOTES#L77-L84

Electron Cash does not support BCH properly? Who thought it was a good idea to release a half baked crapjob to the public?

If it doesn't support P2PK properly, did I just create a BTC transaction and tried to push it to the BCH network? Would I have lost my money had my Electron been connected to the "wrong" network?

Where can I read more about how the replay protection is supposed to work? Can Electrum show me the transaction in human readable format?

Well now you know then. A grep (or google) will show you what kind of payments Bitcoin can do. Public key and public key hash are the two basic types, then there's stuff like script hash which came later, and tomorrow we'll have witness script hash too.

lol, i did google it before i wrote that thing, and also reading the wiki about transaction types there was no mention about p2pk, so my first guess was that you made a simple mistake.

seeing your new comment i dug deeper and found it finally. so thanks i learned a new thing today
