SHA1 used as MAC algorithm for PKCS12 format

[greygreg87]

Is your feature request related to a problem or specific use case? Please describe.
When writing certificate to PKCS12 format we successfully used solution described in discussion:
SetKeyAlgorithm(NistObjectIdentifiers.IdAes256Cbc, PkcsObjectIdentifiers.IdHmacWithSha256)
But when we check generated certificate format in openssl tool MAC algorithm is SHA1

Describe the solution you'd like
Possibility to configure MAC algorithm

Product deployment
Please complete the following information:

• Deployment format: software,
• Version: .NET Framework 4.8

Additional context
openssl response for command
openssl pkcs12 -info -in <cert_name>.p12:

• for certificate generated using BouncyCastle:
  

• for same certificate imported and exported from Windows:
  

We checked the certificate the following tools but always show SHA2: java keytool, keystore explorer, certivity, xca, windows cert store
