Custom components should use Property Descriptors with the sensitive field enabled to store and retrieve sensitive property values. Alternative uses of the encrypt and decrypt methods require custom implementation.
SSLContextService createSSLContext methods
| Component | org.apache.nifi.ssl.SSLContextService |
| Bundle Group | org.apache.nifi |

| Deprecation Type | Interface Method |
| Deprecated Version | 1.13.0 |
| Migration Difficulty | LOW |
| Migration Type | Method invocation changes |
Migration
The SSLContextService interface is a standard Controller Service that supports TLS communication for network services. The createSSLContext methods accepted a Client Authentication argument that did not apply to SSLContext instances. The replacement createContext method provides the same runtime behavior without requiring any arguments. Updating custom code to compile against Apache NiFi 1.13.0 or greater and switching to the createContext method provides compatibility with Apache NiFi 2.0.0.
Processors
Migrating deprecated Processors and properties requires flow design changes. The steps required range from setting different property values to replacing one Processor with one or more Processors providing similar capabilities.
