SMESH App keystore to CLIWallet json file convertor

SMESH keystore files are encrypted and cannot be used by CLIWallet.

CLIWallet wallet files are simple JSON files containing only the private and public keys.

This utility extracts all the private/public keypairs from a keystore and writes them to individual JSON files.

Usage

smesh2cli -input -password -output

• input e.g. ~/.config/spacemesh/my_wallet_0_2020-04-25T19-40-50.942Z.json
• password - your smesh app password
• output file base e.g. smdata/wallet

A keystore file can contains multiple names key pairs. Assuming that you had two, workKey and funKey, they would be saved as two files smdata/wallet0.json and smdata/wallet1.json. The conversion process will indicate how they were saved.
