As the title says. Is this still being maintained?

It seems it's currently supporting Ruby (~> 2.2)
Do you have any plan to support Ruby ~>3.0?

Has anyone run into this issue?

Hey,
I tried to install the gem on an Ubuntu server in order to run ethereum.rb.
But I got an error. This is the console report

sudo gem install digest-sha3
Building native extensions. This could take a while...
ERROR: Error installing digest-sha3:
ERROR: Failed to build gem native extension.

current directory: /var/lib/gems/2.3.0/gems/digest-sha3-1.1.0/ext/digest

To see why this extension failed to compile, please check the mkmf.log which can be found here:

It seems the command fprintf(intermediateValueFile, text); in intermediateValues.c does not precise the type of text variable thus raises a warning and stops the compiler (Ubuntu has not been compiling with such warning since some recent update).

Would simply remplace fprintf(intermediateValueFile, "%s", text) fix the issue ?

As of Ruby 2.2.0, digest-sha3 v1.0.2 now produces a TypeError. The problem also occurs in the current 2.3.0-dev build.

The problem doesn't occur in earlier versions of Ruby (verified: 1.9.3-p448, 2.0.0-p451, 2.1.2, 2.1.5).

Example:

2.2.0> require 'digest/sha3'
 => true
2.2.0> Digest::SHA3.digest("foo")
TypeError: wrong argument type Digest::SHA3 (expected digest)
    from (irb):2:in `reset'
    from (irb):2:in `digest'
    from (irb):2:in `digest'
    from (irb):2
    from /Users/bbuckley/.cache/rbenv/versions/2.2.0/bin/irb:11:in `<main>'

Greetings,

I tested out Digest::SHA3.hexdigest in ruby 1.9.3-p392 and this core dumps ruby when passed nil. This was tested on out an amazon instance: "Linux ip-10-197-43-170 3.2.39-6.88.amzn1.x86_64 #1 SMP Sat Mar 2 05:13:37 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux"

Here is demonstration:

This works fine in ruby 2.0.0

Hey,

I'm trying to find a SHA3 library for Ruby, but it seems like every library (this one included) is, if I'm not mistaken, using an old version of Keccak for validation, not the actual standardized SHA3.

The most recent SHA3 test vectors say that the hash of the blank string should be:

A7FFC6F8BF1ED76651C14756A061D662F580FF4DE43B49FA82D80A4B80F8434A

however, in this library, it works out to:

C5D2460186F7233C927E7DB2DCC703C0E500B653CA82273B7BFAD8045D85A470

After some research, I found some pages that calculate both the original keccak and the sha3, and it confirms that the first output is correct. Here's one such page:

https://www.npmjs.com/package/js-sha3

And here's a blank test vector from the original docs:

http://csrc.nist.gov/groups/ST/toolkit/documents/Examples/SHA3-256_Msg0.pdf

Which agrees with everything else, and shows that the output is wrong.

Is there any chance of getting this fixed? Or of adding an option to use the new variation?

I am trying to use digest-sha3-ruby to get an identical digest that is being created from a library that internally uses ethers https://github.com/ethers-io/ethers.js and ethers uses js-sha3 https://github.com/emn178/js-sha3 internally.

The thing that is particually challenging about all of this is, the version of js-sha3 ethers is using throws the error "INVALID_ARGUMENT - hex string must have 0x prefix" error if what is passed to it does not have '0x' at the start of it... So this library is prefixing the string going to the keccak256 function with '0x'...

And, it seems this keccak256 implementation is operating off of bytes, for example, both '0x0' and '0x00' have the same output:

ethers.utils.keccak256('0x0')
'0xbc36789e7a1e281436464229828f817d6612f7b477d66591ff96a9e064bcc98a'
> ethers.utils.keccak256('0x00')
'0xbc36789e7a1e281436464229828f817d6612f7b477d66591ff96a9e064bcc98a'

In ruby, totally different output:

[5] pry(main)> Digest::SHA3.new(256).hexdigest('0')
=> "044852b2a670ade5407e78fb2863c51de9fcb96542a07186fe3aeda6bb8a116d"
[6] pry(main)> Digest::SHA3.new(256).hexdigest('00')
=> "e3f0ae350ee09657933cd8202a4dd563c5af941f8054e6d7191e3246be378290"

# or even

[2] pry(main)> Digest::SHA3.new(256).hexdigest('0x0')
=> "77b7d82d931e1a403db0240b08c0716665eec4664af617c457918e4a67bc1810"
[3] pry(main)> Digest::SHA3.new(256).hexdigest('0x00')
=> "27489e20a0060b723a1748bdff5e44570ee9fae64141728105692eac6031e8a4"

I am wondering is there something I can do to get digest-sha3-ruby to have the same output as ethers.utils.keccak256() ?
