TransmissionEncryptionProcessor

Background and Use Cases

In earlier versions of the decision platform, sensitive data such as user passwords were transmitted without encryption or with only base64 encoding. Version 10.0 introduced the TransmissionDecryptProvider interface to support encrypted transmission, but since encryption is a reversible operation, the decryption order could not be guaranteed when multiple plugins coexisted. In April 2021, the official team replaced it with the exclusive TransmissionEncryptionProcessor interface to improve reliability. The old interface has been deprecated.

Interface Definition

package com.fr.decision.fun;

import com.fr.stable.fun.mark.Immutable;
import com.fr.stable.fun.mark.WebCoalition;

public interface TransmissionEncryptionProcessor extends Immutable, WebCoalition {
    String MARK_STRING = "TransmissionEncryptionProcessor";
    int CURRENT_LEVEL = 1;

    String encrypt(String plainInfo);
    String decrypt(String encryptionInfo);
}

Deprecated legacy interface (retained for backward compatibility only):

package com.fr.decision.fun;

import com.fr.stable.fun.mark.WebCoalition;

@Deprecated
public interface TransmissionDecryptProvider extends WebCoalition {
    String MARK_STRING = "TransmissionDecryptProvider";
    int CURRENT_LEVEL = 2;

    String decrypt(String encryptionInfo);
}

Supported Versions

Plugin Registration

Add the following node to plugin.xml:

<extra-decision>
    <TransmissionEncryptionProcessor class="your class name"/>
</extra-decision>

To maintain backward compatibility with older versions (not recommended):

<extra-decision>
    <TransmissionEncryptionProcessor class="your class name"/>
    <TransmissionDecryptProvider class="your class name"/>
</extra-decision>

How It Works

Implementations are retrieved via:

• ExtraDecisionClassManager.getInstance().getSingle(TransmissionEncryptionProcessor.MARK_STRING)
• getArray(TransmissionDecryptProvider.MARK_STRING)

The system uses TransmissionTool to call these implementations to encrypt/decrypt sensitive information in transit.

TransmissionEncryptionProcessor is Immutable (exclusive), meaning only one plugin implementation can be active in the environment at a time.
