Re: GSoC 2018 - Modern cryptographic algorithms to netpgp, netpgpverify


Thank you for accepting my proposal for GSoC 2018. Since, it is the community bonding period, please guide on the steps to discuss about the project in more details and move with the environment setup and start with understanding the required codebase. 

Please provide your feedback on my approach, work and communication so that I can improve on it and we can make most out of the project.

There is no such exact implementation for ed25519 or salsa20 hash, but there are few open source modified implementations, I can take reference from them( as they have different licenses so cannot use them directly )  and implement the required algorithms based on our need, combining with reading the relevant papers and documents.

  • Is the project a port of software, or a rewrite? (remember: No GPL in the NetBSD kernel!)
  • No. But it will use already existing algorithms and implementation of those algorithms.
what existing implementation do you intend to use?

Hi Alistair,

Please go through the proposal for GSoC project. Here is the link: GSoC proposal

Please provide your valuable comments, as to how can I be selected as I really want to be a part of this experience.

Formatting is not quite good. Please suggest on formatting also, as nothing was mentioned in the guidelines.

When you read the answers below, I can understand if you think I'm being difficult.

But this is how we can work out whether you've understood the task, and have thought about how you'd go about it.

Yeah, netpgpverify is the new, all-in-one, no pre-reqs codebase solely for the verification part of signatures.

ed25519 also needs to be added to netpgp, which is the older and more crufty code base which covers signing and verification.

So, as netpgpverify is the new code base for verification part, netpgp will be used for only the signing part or for both as it used to do?

See the project specification - both are needed.

But before any code is touched, we'd need to know what gpg constants uses for these algorithms, since they're not in RFC 4880, and so we can interoperate with gpg in verifying and signing.

We can get the ed25519 specifications from RFC8023 and see for the constants but I have a doubt as to what are these constants that you referred?

Look further.

Think of the job that netpgpverify and netpgp do, and how they interoperate with other software.

We need to know what extra parts are needed (from different sources, along with their licences), and any other prereqs we might need for both netpgpverify and netpgp.

I am not able to get what do you mean by extra parts and prereqs, can you explain, please?

Think of other things that will be necessary to accomplish the task. 

In summary, I'd like to see what you think will be necessary. I'd like to see the thoughts that go into how to accomplish a design and programming task, what tests are necessary, and what to be wary of in the implementation. Not in email, but in the proposal that you write - how you will accomplish (and surpass) the goals.
You (and anyone else) should now have enough information -- from the project specification, and from previous email --  to generate a proposal for the project.


PS. One copy of email is enough, thanks :)

Hi Harsh,

I've been talking to others about it, but yours is the first mail I've received.

C proficiency is necessary. C++ not needed.

I can help you out with any specific questions you have - please mail them here (i.e. to tech-crypto, CC me).

Hi Alistair,

Sorry for contacting you soo late for the above-mentioned project. Could you provide me with help regarding the project so that I can work on it for GSoC? Also, do you have anyone else preparing for it or can I continue with this?

My knowledge of C and C++ languages is intermediate.
