I read the JSONRPC document of Parity these days.
And I want to encrypt my message with the public key and private key of the accounts in Parity.
I found a JSONRPC in this web parity_encryptMessage
But it refers that
"Encrypt some data with a public key under ECIES."
And one of its parameters is
"Hash - Public EC key generated with secp256k1 curve, truncated to the last 64 bytes."
I can't understand it. I don't know how to get it. It generate by Parity or it should generate by myself? Please give me some advice. Thanks a lot~
