    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 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...
