Persisting Sensitive Data

凭据存储API允许您安全地存储敏感用户数据,如密码,服务器URL等.

如何使用

使用PasswordSafe处理凭据.

Retrieve stored credentials

String key = null; // e.g. serverURL, accountID
CredentialAttributes credentialAttributes = createCredentialAttributes(key);

Credentials credentials = PasswordSafe.getInstance().get(credentialAttributes);
if (credentials != null) {
  String password = credentials.getPasswordAsString();
}

// or get password only
String password = PasswordSafe.getInstance().getPassword(credentialAttributes);    

private CredentialAttributes createCredentialAttributes(String key) {
    return new CredentialAttributes(CredentialAttributesKt.generateServiceName("MySystem", key));        
}    

###存储凭据

CredentialAttributes credentialAttributes = createCredentialAttributes(serverId); // see previous sample
Credentials credentials = new Credentials(username, password);
PasswordSafe.getInstance().set(credentialAttributes, credentials);

To remove stored credentials, pass null for credentials parameter.

##存储

默认存储格式取决于操作系统.

OS	Storage
Windows	File in KeePass format
macOS	Keychain using Security Framework
Linux	Secret Service API using libsecret

Users can override the default behavior in Preferences | Appearance & Behavior | System Settings | Passwords.
