getSignForLogin

Generates signatures to verify the issuer. It is mainly used to generate signatures for login-related information such as ID tokens and access tokens.

wepin!.getSignForLogin(privateKey: privateKey, message: "")

Parameters

  • privKey <String> - The authentication key used for signature generation.

  • message <String> - The message or payload to be signed.

Returns

  • String - The generated signature.

The authentication key (privKey) must be stored securely and must not be exposed to the outside. It is recommended to execute the getSignForLogin() method on the backend rather than the frontend for enhanced security and protection of sensitive information.

Example

let privKey = '0400112233445566778899001122334455667788990011223344556677889900'

finalize

wepin!.finalize()

This method finalizes the Wepin Login Library.

Parameters

  • void
