In this example, first module is to convert payload from XML to CSV format using MessageTransformBean. Then PGPEncryption module used to apply signature and encryption to CSV message, and finally send out to target using SFTP adapter or any other
SAP SFTP Receiver Adapter with Dynamic Filename
This example show SAP own SFTP receiver adapter to connect to Concur SFTP site, to send master data to Concur. Enter Server host name, default port for SSH is 22. The Server fingerprint can get from SFTP client, like FileZilla,

Below show example error of PKIX path building failed when do a REST HTTP call and how to solve it: Error message: Go to website that the do REST HTTP call, this is firefox browser, click that: More: View Certificate:
Seeburger PGP Module to Sign and Encrypt Payload
PGP general flow (X send to Y): At X side sending, sign with X private key, Encrypt with Y public key. At Y side receiving, verify with X public key, Decrypt with Y private key. Below show an example usage
Seeburger SFTP Receiver Adapter with Dynamic Filename
Below show example usage of SFTP receiver adapter: Host name is target SFTP host want to connect. Port is default 22. Known hosts store is the key store view that contain SSH cert of the host. For the first time
