Use given ECDH and perform the key agreement using curve secp112r1. Print out the paramaters (using OpenSSL) of secp112r2 and describe them shortly.[3]

3. Sign and verify the signature of document "document_UCO" (UCO stands for you UCO) using ECDSA that use sha512 for hashing[2]. 

4. Generate chain of certificates: root CA, sub-ordinate CA (sub-ordinate CA signed by root CA) and end-user cert.[3]
