We should manage to move algorithm-specific logic inside `MacData` as much as possible, ideally everything. For example, instead of letting `macData.getDigestAlgName()` returning either "HmacSHA256" or "PBMAC1", it should return the final `macAlgorithm` we need. If the calculation and verification must be different, they can also be moved into `MacData`.
