[shamatar]

What kind of keystore do you have? Is it from Geth?

@shamatar
keystore
eg:
{"address":"f13445645b52f597ca92e6f7c9987b16bc07ddb6","crypto":{"cipher":"aes-128-ctr","cipherparams":{"iv":"9ade19530af3e29106ed908bb46f3041"},"ciphertext":"d6236558690e5e9952ead703a4bc5bbe17a49cf47e8d8b4896fc46149c79586e","kdf":"scrypt","kdfparams":{"dklen":32,"n":4096,"p":6,"r":8,"salt":"127c2275de524cc6bd7ce21f804882d7aded732a77b5875026b56b97b1b1305a"},"mac":"288313bb2bb4ceccfa53f81e5c2803f45992222d3da74b94aa38e2a219088063"},"id":"e2092a8b-68bd-4801-bc3e-555e5dfc0878","version":3}

[shamatar]

There is an example for it in tests too

        guard let data = Data(...) // here is data from your keystore JSON
        guard let keystoreData = getKeystoreData() else {return}
        guard let keystoreV3 = EthereumKeystoreV3.init(keystoreData) else {return} // there is also an init() taking a JSON String
        let web3Rinkeby = Web3.InfuraRinkebyWeb3()
        let keystoreManager = KeystoreManager.init([keystoreV3])

Would you try and give your feedback

[QA411]

@shamatar My goal is to get the private key by keystore and password.

[shamatar]

If you want to export the private key - just use the

public func UNSAFE_getPrivateKeyData(password: String, account: EthereumAddress) throws -> Data

Otherwise if you follow the normal workflow for sending ETH, tokens or interacting with a smart-contract you can use an encrypted keystore and only supply a password to decrypt it when sending a transaction.

thanks for reply! other question,privateKey is Data type. How to transform type?
eg: 8b4466d6d85fb8f8c90e0008987b09af9b249d1599d36dcbdae2d9e3ede8d779

I tried Base64EncodingOptions ......

[shamatar]

You need to encode as hex, please check the SO for examples
