Swisstronik SDK Go
This package provides a thin wrapper for Deoxys-II-256-128 (and maybe other things in the future) for usage v/ Swisstronik chain.
Currently, it exposes the following functions:
- EncryptState/DecryptState for smart contract enc/dec
- EncryptECDH/DecryptECDH for arbitrary data enc/dec with user's private key and node public key
- EncryptECDHWithRPCURL/DecryptECDHWithRPCURL - convenience encryption with pre-fetching node public key
- FetchNodePublicKey - for fetching node public key via JSON-RPC
- GetCurve25519PublicKey - for getting public key from private key
- DeriveEncryptionKey - for deriving a new master key using the other one and salt

Functions ¶
func DecryptECDH ¶
func DecryptECDHWithRPCURL ¶
DecryptECDHWithRPCURL fetched node public key from rpcURL and decrypts provided value using provided encryption key
func DecryptState ¶
func DeriveEncryptionKey ¶
DeriveEncryptionKey derives encryption key using master key and salt
func EncryptECDH ¶
EncryptECDH encrypts provided value using encryption key, derived from user private key and node public key.
func EncryptECDHWithRPCURL ¶
EncryptECDHWithRPCURL fetched node public key from rpcURL and encrypts provided value using encryption key, derived from user private key
func EncryptState ¶
EncryptState encrypts smart contract state using simmetric key derived from master key only for specific contract. That allows us to improve cryptographic strength of our encryption scheme.
As an output, this function returns vector which contains 15 bytes nonce and ciphertext.
