Ecoji ๐Ÿฃ๐Ÿ”‰๐Ÿฆ๐Ÿ”ผ

Ecoji encodes data as 1024 emojis, its base1024 with an emoji character set. As a bonus, includes code to decode emojis to original data.

Many have asked how Ecoji compares to base64. The short answer is that Ecoji is more bytes, but less visible characters. 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 to snapcraft.io and can be installed with :

sudo snap install ecoji

Examples of running

Encode example :

$ echo "Base64 is so 1999, isn't there something better?" | ecoji

Decode example :

$ echo ๐Ÿ—๐Ÿ“ฉ๐ŸŽฆ๐Ÿ‡๐ŸŽ›๐Ÿ“˜๐Ÿ”ฏ๐Ÿšœ๐Ÿ’ž๐Ÿ˜ฝ๐Ÿ†–๐ŸŠ๐ŸŽฑ๐Ÿฅ๐Ÿš„๐ŸŒฑ๐Ÿ’ž๐Ÿ˜ญ๐Ÿ’ฎ๐Ÿ‡ต๐Ÿ’ข๐Ÿ•ฅ๐Ÿญ๐Ÿ”ธ๐Ÿ‰๐Ÿšฒ๐Ÿฆ‘๐Ÿถ๐Ÿ’ข๐Ÿ•ฅ๐Ÿ”ฎ๐Ÿ”บ๐Ÿ‰๐Ÿ“ธ๐Ÿฎ๐ŸŒผ๐Ÿ‘ฆ๐ŸšŸ๐Ÿฅด๐Ÿ“‘ | ecoji -d
Base64 is so 1999, isn't there something better?

Concatenation :

$ echo -n abc | ecoji
$ echo -n 6789 | ecoji
๐ŸŽฅ๐Ÿค ๐Ÿ“ ๐Ÿ
$ echo XY | ecoji
$ echo ๐Ÿ‘–๐Ÿ“ธ๐ŸŽˆโ˜•๐ŸŽฅ๐Ÿค ๐Ÿ“ ๐Ÿ๐Ÿฒ๐Ÿ‘ก๐Ÿ•Ÿโ˜• | ecoji -d

Make your hashes more interesting. When using for hashes, consideration should be given for older systems without utf8 emoji support, different fonts, and similar emojis.

$ cat encode.go  | openssl dgst -binary -sha1 | ecoji
$ echo ๐ŸŒฐ๐Ÿ๐Ÿก๐ŸšŸ๐Ÿ”ถ๐Ÿฆ…๐Ÿ˜ก๐Ÿ˜บ๐Ÿš†๐Ÿ‘๐Ÿ•ก๐Ÿฆž๐Ÿ“๐Ÿ–Š๐Ÿ™€๐Ÿฆ‰ | ecoji -d | openssl base64
$ cat encode.go  | openssl dgst -binary -sha1 | openssl base64

Make a cool URL shortener. 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)
https://ecoji.io/๐Ÿ˜‰๐Ÿˆš๐Ÿ› ๐Ÿ„

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

Usage :

$ ecoji -h
usage: ecoji [OPTIONS]... [FILE]

Encode or decode data as Unicode emojis. ๐Ÿ˜

    -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.

Build instructions.

This is my first Go project, 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
