How to generate Terra's private key like the one Terra Station Wallet produces?

Does anyone know how the Terra Station Wallet generates the 364 characters Private Key? I am looking for a way to generate this 364 characters Private Key using terra-sdk, but the length of the mk = MnemonicKey()'s mk.private_key is not 364 characters.

Appreciate any help

Solution

  • You sparked my curiosity. I went through the Terra Station code (I chose mobile) to see how they do it. I first searched for where in the UI was the “Export Private Key”; it looks to be the encrypted Key string in AuthDataValueType.

    Here’s where they read it out of keystore. https://github.com/terra-money/station-mobile/blob/f74c4224986fd9ed32b4380b537e9ae13ca05c3e/src/utils/authData.ts#L15

    Here’s where they create it for a newly recovered wallet. https://github.com/terra-money/station-mobile/blob/3ec15b9a620432dee47378f5b6e621d93780748a/src/utils/wallet.ts#L66

    And, lastly here are the encrypt util functions. https://github.com/terra-money/station-mobile/blob/3ec15b9a620432dee47378f5b6e621d93780748a/src/utils/crypto.ts

    This is all NodeJS/ReactNative code so you would need to create the same encrypt/decrypt, password and storage flow in Python, if necessary.
