ethers v6.13.4 Wallet.fromEncryptedJson wrong password error code message source

💡 Result:

In ethers v6.13.4, the Wallet.fromEncryptedJson method does not return a specific error code for an incorrect password [1][2]. Instead, it throws an error with the message "incorrect password" [1][3]. This occurs within the decryptKeystoreJson function (which is called by Wallet.fromEncryptedJson) [1][2]. The library uses an internal assertion to verify the keystore's message authentication code (MAC) against the computed one, and if they do not match, it explicitly throws an error: assertArgument(computedMAC === spelunk(data, "crypto.mac:string!").toLowerCase, "incorrect password", "password", "[ REDACTED ]"); [1][3] While ethers v6 utilizes a comprehensive system of error codes for most operational and input-related failures (such as "INVALID_ARGUMENT" or "UNSUPPORTED_OPERATION") [4][5], the "incorrect password" error is an authentication-specific failure that relies on a human-readable message rather than a standardized machine-readable error code [1][4]. Consequently, you should identify this specific failure by checking if the error's message property equals "incorrect password" rather than relying on an error code [1].

Match ethers’ wrong-password error fields before retrying.

The lockfile resolves ethers 6.15.0. Retry only errors with code === "INVALID_ARGUMENT", argument === "password", and shortMessage === "incorrect password". Re-throw all other errors unchanged. Add tests for wrong passwords, malformed JSON, corrupted ciphertext, and prompt failures. A corrupted ciphertext with an unchanged MAC produces the same ethers error as a wrong password and is not distinguishable here.

Apply the keystore existence check to the recreation path.

This check only covers the initial createKeypairByName(accountName, false) call. The invalid-format recovery at Lines 169-172 calls createKeypairByName(accountName, true) and immediately reads keystorePath. If recreation fails, getAccount still throws an unhandled ENOENT. Use one shared create-and-verify helper before both readFileSync calls.
