The supported algorithms that are available are DES, PGP, PGP_RFC4880, Base64, TripleDES, AES256, AES128, RC2-40, RC2-64, and RC2-128.
The configuration for each algorithm is mentioned in the sections below.
DES Encryption Algorithm Configuration
The following are the configurations of the individual algorithms:For DES , the configuration panel is as shown in the Figure 2. Set the following fields accordingly.
- Encryption Key: Specify key which is used to encrypt the incoming data. Specify 32 digit key for AES256, 16 digit key for AES128, 16 digit key for DES, 24 digit key for TripleDES, 5 digit key for RC2_40, 8 digit key for RC2_64 and 16 digit key for RC2_128
- Allow Padding: Choose yes to allow padding to the key to make exactly the value required for the mentioned algorithm. It has to be chosen only when we know that encrypted data key is also padded.
- Transformation: <>

Process Message Based on Property
The property helps components to skip certain messages from processing.
Refer to the Process Message Based On a Property section under the Common Configurations page.
Cleanup resources (excluding connection) after each document
This closes all the resources except for the connection after every request. If the less processing time is more important the less memory usage, then it is recommended to disable this property and vice versa.
For more details, refer to the respective section under in the Common Configurations page.
Target Namespace
Refer to the Target Namespace section under the Common Configurations page.
Monitoring Configuration
Please refer to the Monitoring Configuration section in Common Configurations page.
