There is slight change on mmh3 hash genration with favicon flag vs the default one, the default one can be adapted to mimic the pythoic (-favicon) mmh3 hash.

echo https://mta-sts.forwarding.hackerone.com/favicon.ico | ./httpx -hash mmh3 -silent
https://mta-sts.forwarding.hackerone.com/favicon.ico [2594644036]

echo https://mta-sts.forwarding.hackerone.com | ./httpx -favicon -silent

As it's unclear the types of hashes are supported, this information can be made available to help menu by printing hashType

-hash string         Display response body hash (supported: md5,mmh3,sha256,sim)

This bug is because I forgot to convert the final mmh3 hash to int32.

just change:
common/hashes/Mmh3

func Mmh3(data []byte) string {
	var h32 = murmur3.New32WithSeed(0)
	h32.Write(stdBase64(data))
	return fmt.Sprintf("%d", int32(h32.Sum32()))
}

test:
echo "https://www.bilibili.com/" | httpx -favicon -hash mmh3

https://www.bilibili.com/favicon.ico [-1825654886] [-1825654886]
