# 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 secret key is
|
|
available. On MacOS, returns true if Keychain is available.
|
|
On Windows, returns true with no other preconditions.
|
|
|
|
### `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.
