# decryptKeystoreJson

```ts theme={null}
function decryptKeystoreJson(
   json, 
   _password, 
progress?): Promise<KeystoreAccount>
```

Resolves to the decrypted JSON Keystore Wallet `json` using the `password`.

If provided, `progress` will be called periodically during the decrpytion to provide feedback, and if the function
returns `false` will halt decryption.

The `progressCallback` will **always** receive `0` before decryption begins and `1` when complete.
