A Base122 byte-to-text encoder using format referenced in http://blog.kevinalbs.com/base122

Base122 Encoder and Decoder

WIP

Build

Jar Sign

If you want to jar sign you need to provide a file keystore.jks in the root folder with the correct credentials set in environment variables ( OPENSOURCE_PROJECTS_KS_PW and OPENSOURCE_PROJECTS_KEY_PW); alias is set as pfopensource.

If you want to skip jar signing just change the skip configuration in the pom.xml jar sign plugin to true:

<skip>true</skip>

Build with Maven

Use maven (3.1+) to create a jar including all dependencies

mvn clean install

Tech Stack

• Java 7

base122-java's Issues

Decoder code issue

https://github.com/patrickfav/base122-java/blob/master/src/main/java/at/favre/lib/encoding/Base122.java#L124

To loop through the UTF-8 encoded string, you should use:
char[] utf8Bytes = base122Data.toCharArray();

instead of:
byte[] utf8Bytes = base122Data.getBytes(StandardCharsets.UTF_8);

Because a byte can only represent a partial UTF-8 character and the range of a byte is -128 to 127, so in line 128, the if statement will always be false (a byte will never larger than 127).

Decode and Encode test fail for me

I cloned the repo and ran the test package. I like the Monte-Carlo nature of the tests!

Decoder:

Failures:
DecoderTest.decode:16 arrays first differed at element [0]; expected:<68> but was:<-2>

Encoder:
