A POC of using Mermaidjs instead of PlantUML for diagrams.

This covers how majority card data flows....

    alt If card data was null
        CardDataService ->> WalletCardService : GetCardById(userId, cardId) to get CardIssuer
        WalletCardService ->> CardDataService : Response (Card Issuer information)
        CardDataService -x CardDataService : Save card data (Refer **Save Majority Card Data** file)
    else If card data was not null
        CardDataService ->> CardDataDB : Get encrypted card data by CardId GetByCardId
        CardDataDB ->> CardDataService : Response
        CardDataService ->> AzKV : Get encrypted DEK from Secrets storage
        AzKV ->> CardDataService : Encrypted DEK
        CardDataService -x AzKV : Decrypt DEK with Master Key in HSM
        AzKV -x CardDataService : DEK in clear text
        CardDataService -x CardDataService : Decrypt Card Data

        alt If decrypted data does not contain card number or cvv or expiry date
            CardDataService -x CardDataService : Save card data (Refer **Save Majority Card Data** file)
        end
    end

    CardDataService -x CardDataService : Decrypt With Master HSM and Encrypt with Client PK (refer **Decrypt and Return Card Data** file)
    CardDataApi -x Elastic : Log Service Response (Truncated)
    CardDataService ->> CardDataApi: Get Card Data Response (Encrypted Card Data, CardId, UserId)
    CardDataApi ->> AppUser: Get Card Data Response (Encrypted Card Data, CardId, UserId)
