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.
