🙏 📎 An easier way to compare hashes /fingerprints, when dealing with the human weak link 🔗 🎉
A curated list of 256 emojis that are not entirely similar. Using http://www.webpagefx.com/tools/emoji-cheat-sheet/ and http://www.unicode.org/emoji/charts/full-emoji-list.html to compare them. With 256 as that is 8bit/1byte, and the hexadecimal output that is 2 hex characters.
So 2 hex positions are 1 emoji! Would you rather compare 60 hexadecimal characters or only 30 emoji?! 😺
For information on the draft for broader practice, see the draft. Perma-URL:
go get github.com/emojisum/emojisumThis uses github.com/kyokomi/emoji to print to the console, but also gives the string ouptut for easy pasting to github/markdown.

Rather than relying on this simple tool to do the checksum itself, you will likely want to rely on OpenSSL or coreutils for checksumming. emojisum can just take those formats on stdin:
$> sha1sum main.go | emojisum -pg 7656835947b4c6da272023c56b6f2529511bf88b main.go :jp::gb::metal::goat::family::rocket::smiley_cat::swimmer::chocolate_bar::cactus::candy::smile::honeybee::house::cherries::cloud::fries::bow::wavy_dash::musical_score: main.go 🇯🇵 🇬🇧 🤘 🐐 👪 🚀 😺 🏊 🍫 🌵 🍬 😄 🐝 🏠 🍒 ☁️🍟 🙇 〰️ 🎼 main.goLike so:

Use the golang library to access the mapped emoji words:
package main import ( "fmt" "github.com/emojisum/emojisum/emoji" ) func main() { for i := 0; i < 255; i++ { fmt.Printf("%d (%2.2x):\n", i, i) for _, word := range emoji.Map(byte(i)) { fmt.Printf(" - %s\n", emoji.CodepointToUnicode(word)) } } }In ./contrib/emojisum-rs/ you'll find a rust library for emojisum.
cd ./contrib/emojisum-rs/ cargo buildcargo test
