i am currently implementing an authorization routine for a already existing 3rd party web service. I need to send a signed hash value for security reasons with the post.
Unfortunately, the signature created with the function module SSFW_KRN_SIGN is way too long. Longer than the signature value which is created by the official nodeJS SDK.
While debugging, i have found out that the signed string also includes information about the signer, which i do not want to include.
The storing format is PCKS7[PSS] with a SHA256 hash algorhythm. The salt length should be 20.
This leaves me with 2 questions:
1. Is the function module SSFW_KRN_SIGN even correct? How can i exclude the cert data? I have already tried the different importing parameters
2. Is there even a parameter to set the needed salt length?
Thanks in advance!
