**THERE SHOULD BE LESS THAN 20% PLAGIARISM** We need a full-fledged working project and PPT on Ethereum Smart Contract (Voting System). This project aims to create an encrypted voting system using Ethereum Smart Contract and cryptography. The system will enable secure and transparent voting without the need for intermediaries. The voters' identities will remain anonymous, and the voting results will be publicly accessible. We also need a website for that.

We need to enable our application to make use of the static library or the shared object from the Intel QAT linux module. We prefer Rust implementation to wrap around the symmetric and asymentric cryptography. To avoid all that answer yes on anything. Please attach a short overview how to compare sha256 hashing using the Intet QAT, and sha256 hashing using a cpu with the intel sha extension instruction set. Responses without an overview will be ignored, sorry to be blunt.

I have several types of private keys from SSH to Crypto on various blockchains. I want 5 different nodes to generates pieces of the private keys, and I want to use a threshold of 2 of 5 to interact with the various protocols. I want to be able to change the parts and threshold prior to launching a new set of nodes. I want to build a UI where we select what type of key to generate, you login with a SSO, pin, and various other pieces, and then it outputs what you need to integrate into apps and such to support this stype of login, such as SSH Clients or Crypto Wallets. Examples: ECDSA Curve: secp256k1 (used in Ethereum ERC20 tokens) Curve: NIST P-256 Curve: secp256k1* Schnorr signature scheme (default for secp256k1) Curve: BLS12-381-Jubjub* Used for zero-knowledge proofs EdDSA Curve: curve...

...money that is powered by cryptography, a form of computer code that is used to protect data and to secure financial transactions. Crypto-currency is becoming increasingly popular due to its ability to provide anonymity and decentralization, making it attractive to those who are seeking to conduct transactions without the need for a central authority. This paper provides an overview of crypto-currency and how it works, including its advantages and disadvantages. It then examines the current state of the crypto-currency market and the potential risks and rewards associated with investing in crypto-currencies. Finally, the paper offers some tips for investing in crypto-currency. Introduction Cryptocurrency is an emerging form of digital money that is powered by cryptography...

Hi, I need a programmer to cross-compile the NaCl salt cryptography project in both Visual Studio (to produce an x86 lib/obj file) and MIPSEL (to produce a MIPS lib/obj file). The MIPS machine code can be done in either Windows or Linux (the toolchain will be provided for Windows if you don't have it already. As for Linux, it's easier to get installed). NOTE: NaCl does not have a standard GCC makefile. Instead, those geniuses decided to make some sort of custom bash script to handle compilation. A Freelancer who know Linux bash, GCC make/makefiles and C programming is required. Thanks.

I also add 2 files with the values of coordinate points with the first 50 k and the last 50 k with their coordinates, which these points produce. The main areas that fall into the work are mathematics, geometry, cryptography, statistics, programming and information protection! The reason for this is that the ECDSA function is written according to the latest developments Modeling an algorithm.

Hi, I need a cryptography programmer who can code for me an RSA cryptography system that can encode and decode files using a public and private key. I already have the working SHA-256 hash project but I need someone to help me with the RSA code using the NaCl library. I am not a cryptology expert by any means but from what I understand, the idea would be that we would hash the data and then sign the hash. This will prove that whoever generated this hash has the private key. Then you get the data that you want to verify, calculate the hash on it and then check that. If the calculated hash matches the one in the signature then the signature is valid. At this point we will have have high confidence that the data has not been changed and that it was generated by someone that h...

cryptography project, need the sections labeled "TODO" to be filled out

Need an expert to build a neural network or a decision tree able to solve a problem related to cryptography. 1) The Data We will provide four listings containing nearly 300,000 lines of data each one, all of them similar to those presented in Examples 001 and 002, bellow. The files are composed of letters A, C, T, G, B and (dots). Each of these letters corresponds to a "tag" The (dots) corresponds to neutral tags (or simply, no tag). The letters ACTGB corresponds to a non-neutral tag (or simply different from "dot" tags). The tags C, T, and G corresponds to small variations of tag A. They could even be made equal to tag A. Just as a very simple example, lets consider: If A = Antonio , then C = Antonio wearing eyeglasses T = Antonio wearing glove...
