Hi, I need a system that allows: 1. User uploading an excel spreadsheet containing list of items to be code signed 2. generate a Hash function on the item string and retrieve the information digest of the item to be code signed 3. Code sign the hash digest using RSA private key 4. install the above scripts as an API system in client server that communicates with the main root server. -> Graphic user interface will be provided and a step by step guide in flow chart will be shown. Please bid for this project only if you know how to perform cryptography functions, such as using openssl libraries. All the encryption and decryption functions are provided at [login to view URL] If you are comfortable or have worked on prior project that does the function from the above link, then you should find the project comfortably easy to manage.

RSA public and private key 2. .P12 and .pem file format 3. Hash function, ie. sha1() 4. Encryption and decryption using RSA (Or code Signing using private key) 5. Installation of API system
