Title: Electrum 3.0.5 Encrypted Message Error non-hexadecimal number Post by: QlooQl on January 26, 2018, 03:15:13 PM I'm using Electrum 3.0.5 and when I try to encrypt a message I get the following error:
non-hexadecimal number found in fromhex() arg at position 0 I'm using my public key (not my address) and all my message says is hello I don't have any spaces and triple checked my public key is correct. Anyone else experiencing this issue?

are you copy pasting your public key or right clicking on the address and selecting Encrypt/Decrypt message? you can always paste your public key in a text editor (like NotePad) and see what is wrong with it.

I copied into notepad and tried again from there, no luck. It starts with an x so no i feel like it is correct. My original thoughts were that there was a space, but I tried creating a new wallet and had the same problem.

you can only sign with your (individual) key which will start with 02/03 or 04 for compressed and uncompressed pubkeys respectively.

Ahhh! That was it! Now I can encrypt messages. I did not know there was a master public key vs individual public key. Here is how to find an individual public key in the Electrum wallet: 1. Click View -> Show addresses 2. Open the addresses tab 3. Find your receiving address in the list (or pick any other address you want to use) and right-click it -> Select Details 4. Your public key is shown in the middle box My individual public key started with a 03, which I researched and it is also a 32-bit compressed public key. Thank you for your help! |
