Extend Cryptography Mgt. with RSASignaturePadding parameter

Gijs Franssens on 11/26/2020 3:47:05 PM
Hi,

I am using Crypthograpy Mgt. codeunit of Business Central to sign a string:
CryptographyMgt.SignData(SigningString, PrivateKeyInstr, HashAlgorithmType::SHA256, SignatureOutStream);

I also need to set the RSASignaturePadding parameter, but this is not available at the moment:
https://stackoverflow.com/questions/24263388/rsassa-pss-in-c-sharp

I should be able to set the following parameters:

Hash algorithm: SHA-256
Mask generation function: MGF1
Mask generation algorithm: SHA-256
Salt length: 32 bytes (= 256 bits, same as the hash length)
Trailer field: 1

Can this functionality be added?

Please let me know at what time frame this could be implemented.

Kind regards,
Gijs

Hash algorithm: hs2019 should also be added, because sha-256 will no longer be supported by Q2 2021.
