Change the key encoding from base64 to hex #165

zhangchiqing · 2020-11-21T00:59:04Z

This PR changes the key encoding to be hex instead of the base64, which is the default for []byte

Why this matters?

Before this PR, the key generation will produce networking key and staking keys in base64 , for instance:

go run -tags relic ./cmd/bootstrap key --address "example.com:3569" --role "consensus" -o ./bootstrap/partner-node-infos

will produce :
Note the NetworkPubKey and StakingPubKey are both in base64

{
  "Role": "consensus",
  "Address": "example.com:3569",
  "NodeID": "f1c2f6590da364793f8515712855dae00b135d53de646a4f17f381b28a0cbd2b",
  "Stake": 0,
  "NetworkPubKey": "1b24gbD5zmVgj7r1texoptzoaMZSw1iixRZsvByShLIzyEzKvJP5seTr5U9xF4q7HLrNduc0QaVCqTYsZsSWmQ==",
  "StakingPubKey": "l6Xy4gEisi+kBSocoNdt1P1a+mdzLkOLPS6kXGYDFDFIw24bhBZYOIIz+tZ/QmBxByyByHS0ZurB3SjwOplBz7CVEtm5Fwx4Sk2l16s7izGSED7qzhNvScjVXTZX9Zxm"
}

After the change, it now produces:
Note both NetworkPubKey and StakingPubKey are in hex format

{
  "Role": "consensus",
  "Address": "example.com:3569",
  "NodeID": "0fac00c2ff673307f327a3516f2d41ebaf7ebda9fc7e4b85f20cd7ebdb9d9714",
  "Stake": 0,
  "NetworkPubKey": "aa795dd59ee9fe9f9cca92f162b99a568f08b2f6b63fe9c8f9b7b7e15a606b7c4d81ff698730c6292334816961fe8c4fccb3d8ffdff2fd5a8b50eb063f5d14d0",
  "StakingPubKey": "aa2e0da5a5a8501ae61e163ad51605b9227e14bf30db969d56b036a330b357ca66c2aabc6bac7b44ce6ab65331c6661409786a8a268ecddd1ee5fb247e46bd5e1c6b692208c6dca6a6a71f6f32bf45ff118a0032ee641f08384c01d6784a15af"
}

this check will fail on master, because the previous encoding was base64

Thanks Leo 👏

We could also call pub.String() but that function prefixes the value with 0x

yeah, didn't want to include 0x, because golang's hex.DecodeString doesn't handle that case
