Improving documentation and usage for a noobie

I am looking for a Julia library which could do asymmetric cryptography. As ECC.jl already implements signatures seems the library includes everything I need. However, the API is rather technical. It would be great if there would be documentation on:

• How to generate a private key for ECC?
• How to calculate public key from the private key?
• How to encrypt data with a private key?
• How to decrypt data with the public key?
• Does this library contains a hash function?
