public class IapAuthenticationAutoConfiguration
extends Object

Autoconfiguration for extracting pre-authenticated user identity from Google Cloud IAP header.

Provides:

• a custom BearerTokenResolver extracting identity from x-goog-iap-jwt-assertion header
• an ES256 web registry-based JWT token decoder bean with the following standard validations:
  • Issue time
  • Expiration time
  • Issuer
  • Audience (this validation is only enabled if running on AppEngine, or if a custom audience is provided through spring.cloud.gcp.security.iap.audience property)

If a custom WebSecurityConfigurerAdapter is present, it must add .oauth2ResourceServer().jwt() customization to HttpSecurity object. If no custom WebSecurityConfigurerAdapter is found, Spring Boot's default OAuth2ResourceServerWebSecurityConfiguration will add this customization.

1.1
