Maven dependency fails with "missing, no dependency information available"

As the README suggests, I was using:

<dependency>
    <groupId>ove</groupId>
    <artifactId>ove.blake2b</artifactId>
    <version>alpha.0</version>
</dependency>

in my POM which was working quite well. But today, I saw that my builds were failing with The POM for ove:ove.blake2b:jar:alpha.0 is missing, no dependency information available error. I see that I can no more find your repository in https://mvnrepository.com. Has your repository moved to some new location?

Thanks!

Thread safety

Hi!

In readme I haven't found information about threadsafety of your implementation, can you provide me with this information?

Release on Maven

Is there any plans to release this library on maven-central so it's easy to include in your project? This is the only blake2 java implementation I can find mentioned on: https://blake2.net/ , Is there a better project I should be looking to for prod like applications?

Divergent results for message lengths exceeding 2^64

This issue was kindly brought to my attention by Axel von dem Bruch.

Hi Joubin Mohammad,

I'm currently working on a Blake2b implementation to use later for
password hashing schemes like Lyra2 or Catena
(https://github.com/Beloumi/eck.cologne.crypto). I have see your
implementation on GitHub. This is clearly more comprehensive and
thorough than my version, but maybe there is also sometimes need for a
simple variant.

As I can see, there is a minor not critical bug in the implementation
for messages from 2^64+1 up to 2^64+127 bytes, because the counter
(t[1]) will not be incremented for the last block. So, digests of this
implementation will differ from the C reference implementation.

This can easily fixed by replacing line 446 of the class Blake2b.java
in the function digest()
(currently: this.t[1] += this.t[0] == 0 ? 1 : 0;)
by:
this.t[1] += (t[0] < 0 && buflen > -t[0]) ? 1 : 0;

Best regards
Axel
