A Java implementation of multibase

java-multibase's Issues

Add CI and Code Coverage

Should this project, along with java-multiaddr and java-multihash, have CI and Code Coverage? I don't know much about how to do this for java projects. Is it straightforward?

Requesting to create PR code supporting WordBase-2048 or get feedback on the idea

I would like to discuss and solicit me working on a PR to add another base see: multiformats/multibase#89

Release multibase to maven central

The build of dependent projects rely on this to be found on central or some other mvn repository. I can provide a PR that would allow to run

mvn release:prepare

I could then use the created tag to deploy it to central. Better still, someone else with appropriate authorization could run

mvn release:perform

Here is the PR: #8

Base32, Base64 are not RFC4648 compliance!

According to RFC4648

• Base 32 Encoding is based on 5-bit group
• Base 64 Encoding is based on 6-bit group

However, the implementations of Base 32 and Base 64 in this project is as same as Base58, which is not correct.

This is also conflict with the specs stated here multiformats/multibase:

encoding      codes   name
identity      0x00    8-bit binary (encoder and decoder keeps data unmodified)
base1         1       unary tends to be 11111
base2         0       binary has 1 and 0
base8         7       highest char in octal
base10        9       highest char in decimal
base16        F, f    highest char in hex
base32        B, b    rfc4648 - no padding - highest letter
base32pad     C, c    rfc4648 - with padding
base32hex     V, v    rfc4648 - no padding - highest char
base32hexpad  T, t    rfc4648 - with padding
base32z       h       z-base-32 - used by Tahoe-LAFS - highest letter
base58flickr  Z       highest char
base58btc     z       highest char
base64        m       rfc4648 - no padding
base64pad     M       rfc4648 - with padding - MIME encoding
base64url     u       rfc4648 - no padding
base64urlpad  U       rfc4648 - with padding

Base58Btc encoded byte array or zeros causes StringIndexOutOfBoundsException

Multibase.decode("z111111111111111111111111111111111");

throws this:

java.lang.StringIndexOutOfBoundsException: String index out of range: 33

Managing versions of Java multiformats on Maven

Hi,

How often do you update the versions for the Java multiformats on Jitpack?
I am trying to use the latest version of java-multibase for the java-multiaddr, but I am unable to do so.

Alternatively, how can I force java-multiaddr or java-multihash to use my local version of the java-multibase?

Cheers!
