For pseudonymization, the extractor invokes the native SAP function CALCULATE_HASH_FOR_CHAR. By default the SHA1 algorithm is used. Starting from RFC Module version 1.8.2 two more algorithms are supported - SHA256 and SHA512. All of the pseudonymization happens on the SAP side, extraction runtime.
SHA 256 is supported out of the box, but for SHA512 an additional transport should be imported (attached below). This package is distributed separately from standard RFC Module because older SAP versions don't support the SHA512 method.
The algorithm is defined in the application-local.yml file. Make sure to uncomment the row before saving the change.
Restart the extractor for the changes to take effect.
