dcposch / blakejs Goto Github PK

While re-writing this module in TypeScript, I noticed that the input block is using a Uint32Array, when a Uint8Array would suffice.

blake2s.js line 107

I intend to submit a fix shortly.

Hi @dcposch,

Thank you for the work you've done on implementing BLAKE2! I'm in the works of porting libsodium to the browser and needed BLAKE2, but specifically the salt and personal options in the parameter block. I had some other reservations about your API too, so I took the liberty to copy your implementation, and modify the parts I wanted changed.

I'd like to contribute my changes back to you if you'd like, in the style that you already have here. I can port my changes for both blake2b and blake2s. Is that something you'd be interested in?

You can see my copy (with credits to you) here:

Hi :)

I could PR types for blakejs, have them ready and working. Do you accept PR's?

Best,
Aron

i was trying to think of mascots for this module but it appears there are no celebrities named blake. opening issue in case anyone knows famous blakes I haven't of

Hi, can you provide one file that can have all functions is global and accessible everywhere?

Thanks

Seems like 64 Bit support is possible:

I am trying to use blake2s in Chrome. I already used Require.js.

But I receive the error, "Uncaught TypeError: util.normalizeInput is not a function".

1. Could you kindly give me some guideline on how to implement blakejs in a browser?
2. I am trying to generate blake for files up to 2GB, do I use blake.blake2bHex or "blake2sInit, blake2sUpdate, and blake2sFinall"

Thanks

Hey @dcposch,

we recently got #19 merged by @nazar-pc (thanks for that! :-)). Can you publish a new release to NPM that includes this change? Otherwise we need to publish this separately and we'd like to avoid that.

Best regards,
Marco

Is it possible to calculate hash directly from ArrayBuffer, rather than new Uint8Array(arraybuffer)? Would that avoid additional memory allocation for Uint8Array? (I assume browser allocates same amount of memory for cloning, not sure)

The issue shown in this stack overflow raises itself with use of blakejs on Node with version < 4.x.x

I saw this issue on Travis CI. You can see the fails here:

Cheers.

We at EthereumJS are looking into integrating the Blake2b F function into our project (according to this spec).

I understand the compression function is internal to your project, but it'd help us avoid maintaining a fork of this library or re-implementing the function ourselves. I thought I'd create an issue and ask if you're open to the idea of exporting the compression function (with one extra parameter to determine the number of rounds)?
