Ecoji encodes data as 1024 emojis. It's base1024 with an emoji character set. As a bonus, this repo includes code to decode emojis to the original data they represent.
Many have asked how Ecoji compares to base64. The short answer is that a string encoded with Ecoji will have more bytes, but fewer visible characters, than the same string encoded with base64. With Ecoji, each visible char represents 10 bits, but each character is multi-byte. With base64 each char represents 6 bits and is one byte. The following table shows encoding sha256 in different ways.
| Encoding | Bytes | Characters |
|---|---|---|
| none | 32 | N/A |
| hex | 64 | 64 |
| base64 | 44 | 44 |
| ecoji | 112 | 28 |
Ecoji is published on snapcraft.io and can be installed with :
sudo snap install ecoji$ ecoji -h
usage: ecoji [OPTIONS]... [FILE]
Encode or decode data as Unicode emojis. 😁
Options:
-d, --decode decode data
-w, --wrap=COLS wrap encoded lines after COLS character (default 76).
Use 0 to disable line wrapping
-h, --help Print this message
-v, --version Print version information.$ echo "Base64 is so 1999, isn't there something better?" | ecoji

Four base1024 emojis can represent 1 trillion unique IDs. In the example below af82dd48f7 represents a 5 byte id for a URL in a key value store like Accumulo. When someone enters the URL, the 5 byte id could be used to obtain the actual URL from the database and then redirect.
$ printf "https://ecoji.io/%s\n" $(echo af82dd48f7 | xxd -r -p | ecoji)

Data encoded with Ecoji sorts the same as the input data.
$ echo -n a | ecoji > /tmp/test.ecoji
$ echo -n ab | ecoji >> /tmp/test.ecoji
$ echo -n abc | ecoji >> /tmp/test.ecoji
$ echo -n abcd | ecoji >> /tmp/test.ecoji
$ echo -n ac | ecoji >> /tmp/test.ecoji
$ echo -n b | ecoji >> /tmp/test.ecoji
$ echo -n ba | ecoji >> /tmp/test.ecoji
$ export LC_ALL=C
$ sort /tmp/test.ecoji > /tmp/test-sorted.ecoji
$ diff /tmp/test.ecoji /tmp/test-sorted.ecoji
$ cat /tmp/test-sorted.ecoji

This is my first Go project and I am starting to get my bearings. If you are new to Go I would recommend this video and the tour.
# The following are general Go setup instructions. Ignore if you know Go, I am new to it.
export GOPATH=~/go
export PATH=$GOPATH/bin:$PATH
# This will download Ecoji to $GOPATH/src
go get github.com/keith-turner/ecoji
# This will build the ecoji command and put it in $GOPATH/bin
go install github.com/keith-turner/ecoji/cmd/ecoji
