This sample takes a base64 encoded PDF from a web service and attaches it to an email message with vRealize Orchestrator.
Currently this sample requires enabling local process execution. The local process and file I/O will be performed as the 'vco' user. See the following documentation section for details on how to enable the local process execution:
Set Access to Operating System Commands for Workflows and Actions
An alternative that does not require enabling local process execution would be to use the CryptoEncoding.base64ToMime method in the vRO Encryption Plugin
