OIC - How to configure Dynamic Decryption in OIC

Configure Dynamic Decryption in OIC Based on IsEncrypted schedule Parameter

Use Case

A business receives both encrypted and plain files from an SFTP server. To process both type of files, the integration will use a schedule parameter (IsEncrypted), which will be set to:

'Y' → If the file is PGP encrypted and needs decryption.

'N' → If the file is plain text and does not need decryption.

Goal

• Download the file using the SFTP Adapter.
• Dynamically set the "Decrypt File" option in the Stage File action using the IsEncrypted parameter from the mapper.
• If IsEncrypted = 'Y', enable PGP decryption by setting "true".
• If IsEncrypted = 'N', do not decrypt the file ("false").

Step-by-Step Configuration

1. Add the SFTP Adapter to Download the File

• Drag and drop the SFTP Adapter in the integration.
• Select Download File operation.
• Configure SFTP details (host, authentication, file directory, etc.).
• Store the file in Stage File for processing.

2. Add a Stage File Action to Read the File

• Add a Stage File Action after the SFTP Adapter.
• Select Read File operation.

3. Configure Decryption Dynamically in the Mapper

• Click on Mappings in the Stage File Read action.
• Locate the "Decrypt File" field in the mapping.
• Set the value dynamically using the IsEncrypted parameter:

Expression in Mapper (If-Else Condition)

if ($IsEncrypted = 'Y') then 'true' else 'false'

• This ensures that if IsEncrypted = 'Y', decryption is enabled ("true").
• If IsEncrypted = 'N', the file is read as is ("false").

4. Select PGP Key for Decryption (If Needed)

• If decryption is enabled (true), configure:
  • PGP Private Key (Uploaded in OIC Security).
  • PGP Passphrase.

5. Process the Decrypted or Plain File

• Store the file in Object Storage, Database, or another system.
• Use OIC File Adapter, REST API, or another SFTP Adapter to move/process the file.
