Ecoji ????
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
Installing
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 ????????????????????????????????????????, ecoji -d
Base64 is so 1999, isn't there something better?
Concatenation :
$ echo -n abc, ecoji
???☕
$ echo -n 6789, ecoji
????
$ echo XY, ecoji
???☕
$ echo ???☕???????☕, ecoji -d
abc6789XY
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 ????????????????, ecoji -d, openssl base64

$ cat encode.go, openssl dgst -binary -sha1, openssl base64
GhAkTyOY/Pta78KImgvofylL19M=
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)

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

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
