# safeStorage
|
|
|
|
> Allows access to simple encryption and decryption of strings for storage on the local machine.
|
|
|
|
Process: [Main](../glossary.md#main-process)
|
|
|
|
This module protects data stored on disk from being accessed by other applications or users with full disk access.
|
|
|
|
Note that on Mac, access to the system Keychain is required and
|
|
these calls can block the current thread to collect user input.
|
|
The same is true for Linux, if a password management tool is available.
|
|
|
|
## Methods
|
|
|
|
The `safeStorage` module has the following methods:
|
|
|
|
### `safeStorage.isEncryptionAvailable()`
|
|
|
|
Returns `boolean` - Whether encryption is available.
|
|
|
|
On Linux, returns true if the app has emitted the `ready` event and the secret key is available.
|
|
On MacOS, returns true if Keychain is available.
|
|
On Windows, returns true once the app has emitted the `ready` event.
|
|
|
|
### `safeStorage.encryptString(plainText)`
|
|
|
|
* `plainText` string
|
|
|
|
Returns `Buffer` - An array of bytes representing the encrypted string.
|
|
|
|
This function will throw an error if encryption fails.
|
|
|
|
### `safeStorage.decryptString(encrypted)`
|
|
|
|
* `encrypted` Buffer
|
|
|
|
Returns `string` - the decrypted string. Decrypts the encrypted buffer
|
|
obtained with `safeStorage.encryptString` back into a string.
|
|
|
|
This function will throw an error if decryption fails.
|
|
|
|
### `safeStorage.setUsePlainTextEncryption(usePlainText)`
|
|
|
|
* `usePlainText` boolean
|
|
|
|
This function on Linux will force the module to use an in memory password for creating
|
|
symmetric key that is used for encrypt/decrypt functions when a valid OS password
|
|
manager cannot be determined for the current active desktop environment. This function
|
|
is a no-op on Windows and MacOS.
|
|
|
|
### `safeStorage.getSelectedStorageBackend()` _Linux_
|
|
|
|
Returns `string` - User friendly name of the password manager selected on Linux.
|
|
|
|
This function will return one of the following values:
|
|
|
|
* `basic_text` - When the desktop environment is not recognised or if the following
|
|
command line flag is provided `--password-store="basic"`.
|
|
* `gnome_libsecret` - When the desktop environment is `X-Cinnamon`, `Deepin`, `GNOME`, `Pantheon`, `XFCE`, `UKUI`, `unity` or if the following command line flag is provided `--password-store="gnome-libsecret"`.
|
|
* `kwallet` - When the desktop session is `kde4` or if the following command line flag
|
|
is provided `--password-store="kwallet"`.
|
|
* `kwallet5` - When the desktop session is `kde5` or if the following command line flag
|
|
is provided `--password-store="kwallet5"`.
|
|
* `kwallet6` - When the desktop session is `kde6`.
|
|
* `unknown` - When the function is called before app has emitted the `ready` event.
