You can generate a secp256k1 keypair using OpenSSL, but converting that to an Ethereum address is a bit tricky. The issue is that converting a secp256k1 public key into an address requires the keccak-256 hash function, which is not commonly used and thus will not be built into OpenSSL or GPG. This loads the FIPS 186-3 SigGen.txt for ECDSA and generates an SECP256K1 signature for every hash and message pair. Currently this verifies the vectors it's generating using our ECDSA API, but that API doesn't actually support SECP256K1 right now so this PR also includes code which enables that. If a user wants to share this file with other user, just generate a key based on the other user public key and users private key, and encrypt the AES with this common key so the other user can decrypt and read it. My question is, How to encrypt AES key with secp256k1 keys since I couldnt find any implementation of this in either python or golang.

One of the most common forms of cryptography today is public-key cryptography helps to communicate two system by encrypting information using the public key and information can be decrypted using private key. These keys are using mainly on login to server securely and also transferring data securely.
We can generate these private public keys by various ways.
1) By using openssl.
with password encryption
Generate public key:
2) By using ssh keygen3) using putty-gen for windows.
Download puttyGen from http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html and run it.
You can select one of the key types, SSH-1, SSH-2, and SSH-2 DSA.
SSH-2 is probably better than others but you have to make sure if your system supports SSH-2, if your system ( server) doesnt support it then you better off with SSH-1.
Level of encryption can be set from “Number of bits in a generated key” . Security level can be enhance by using 2048 but again make sure where you are using it and thus follow the recommendation for this value. I prefer 2048 but even with 1024 is much more secure.
Click on generate to create keys. Move your mouse over the empty space to help puttygen to genereate random variables.
Once the key is generated you will see following window.
