<p>For anybody getting "Failed to decode RSA key", this is caused when using an external Tor version >0.4.2.3-alpha. Newer Tor daemon versions automatically give a V3 private key (ED25519) when a hidden service is requested via the <code>ADD_ONION NEW:BEST</code> control protocol command (which Bisq uses on it's first run to generate a HS private key).</p>
<p>I was able to workaround this by manually generating a V2 (RSA1024) key with (replacing <code>$BISK_DATA_DIR</code> with your data dir location):</p>
