Dear Jim
With the SAP Package for SWIFT (SIPS) / SWIFT bundle the main functionality is to implement
1) end-to-end security with HMAC-SHA256
2) generate the XML V. 2. 0 XML companion file, which contains the SWIFT address information (DN = distinguished name)
1) you could use as well for H2H connections as long as your bank accepts LAU
2) needs to replace with the H2H link info
The question is more do you really want to use SIPS - as SIPS needs PI to run.
Or you want to look into other LAU (e. g. PGP).
Best regards
Christoph
