I have binary files containing all of the the components of a private RSA crt: crtCoefficient, modulus, primeExponentP, primeExponentQ, primeExponentQ2, primeP, primeQ, privateExponent and publicExponent. All of the files are exported from Java so they are BIG ENDIAN. Your job is to PROPERLY re-create the private (and public) [login to view URL] someone who knows what they are doing, this is a simple project. I have attached a sample file (crtCoefficient) so you can get an idea of what you will be doing. Your job is to re-create the private key and deliver it to me in PEM format. DO NOT BID FOR THIS JOB UNLESS YOU UNDERSTAND THE JOB. IN YOUR PROPOSAL, PLEASE STATE THAT YOU READ THIS AND UNDERSTAND HOW TO CREATE AN RSA CRT USING THE COMPONENTS! Some other hints/info: The RSA private key structure uses BigInteger objects. You must interpret the attachments as binary files using the proramming language of your choice, reading 4 byte integers to assemble a BigInteger() object with. You then initialize a private key object/crt using the specified params. If the PUBLIC KEY for the private key you created DOESN'T MATCH the attached file '[login to view URL]' (which you will be given upon being awarded the job), you did it wrong.

Hi. I know crypto really well, and I know a lot about RSA. However, I can't seem to open any Java source you attached? Also, I am wondering what is the standard for the PEM file export you need? Like adding -----BEGIN RSA PRIVATE KEY----- and then -----END RSA PRIVATE KEY----- ? Let us discuss in more details ...
