    ...provider that can be used by Xcode, Xcodebuild and codesign, and that talks to our backend service for actual signing operations. We also need an installer that does not require user interaction. We already provide a cross-platform C++ library that connects to the backend, which does the actual crypto operations. A few modifications might be necessary on our side. You will need basic applied cryptography knowledge. You must understand the concepts of code signing, certificate management, and smart card key access in macOS (although no physical smart cards will actually be used). You will contribute platform-specifc knowledge to a team of experienced software developers. Proposals must show required skills (crypto and macOS systems programming). Proposals from applicatio...

    create a message by converting each of these digits 02457801010 to the equivalent (mod 2), so even numbers are written as 0 and odd numbers as 1 Use matrices to describe the full process of sending and receiving this message using a Hamming (15, 11) code, including how the message is encoded, how the parity is checked, how an error is corrected and how the original message is recovered, giving in full all the necessary matrices. Demonstrate the error-correction operation by changing the fifth bit of your encoded message and showing how the correct message can be recovered. Show what happens if the first and second bits of your encoded message are both changed, and comment on your answer.

    This question is about how many codewords there can be in a ternary linear code. Note that m is the number of codewords, not the length of the code. A ternary code uses the symbols 0, 1 and 2 with the properties that 1+1=2, 1+2 = 0, and 2+2 =1. Note that m is the number of codewords, not the length of the code. For each of m = 1, 2, 3, 4, and 9 write down a ternary linear code of length 2 containing m codewords, or explain why there is no such code. In general for what m does there exist a ternary linear code with m codewords? Justify your answer, referencing any research you have done. Marks will be deducted for failure to reference research correctly using the Harvard system.

    Hi. I need a cryptography programmer who can code for me a highly sophisticated elliptic curve cryptography key generator (preferably using OpenSSL) which I can hash with SHA-256. If ECC is too complex, RSA may also be substituted as a replacement as I believe both of these methods use a public and private key. I already have the working SHA-256 hash code but I need someone to help me with the ECC or RSA code. 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...
