Riftborn uses many helper methods from these libraries.

Calculate players hash

TArray<TObjectPtr<APlayerState>> copy = InPlayers;
uint32 hash = 0;

for (int32 i = 0; i < copy.Num(); ++i)
{
    FBPUniqueNetId netId;
    UAdvancedSessionsLibrary::GetUniqueNetIDFromPlayerState(copy[i].Get(), netId);

    FString id;
    UAdvancedSessionsLibrary::UniqueNetIdToString(netId, id);

    hash = FCrc::StrCrc32(*id, hash);
    if (AHumPlayerState* item = Cast<AHumPlayerState>(copy[i].Get()))
    {
        FString team = UEnum::GetValueAsString(item->GetTeam());
        hash = FCrc::StrCrc32(*team, hash);

        FString selectedChar = item->GetSelectedCharacter().PrimaryAssetName.ToString();
        hash = FCrc::StrCrc32(*selectedChar, hash);
    }
}
return hash;

Player killed someone

FBPUniqueNetId a;
UAdvancedSessionsLibrary::GetUniqueNetIDFromPlayerState(PlayerInstigator, a);
FBPUniqueNetId b;
UAdvancedSessionsLibrary::GetUniqueNetIDFromPlayerState(PlayerInstigator, b);

FString aStr;
UAdvancedSessionsLibrary::UniqueNetIdToString(a, aStr);
FString bStr;
UAdvancedSessionsLibrary::UniqueNetIdToString(b, bStr);

TRACE(LogHUM, "%s (%s) has killed %s (%s)",
    *PlayerInstigator->GetPlayerName(),
    *aStr,
    *PlayerInstigator->GetPlayerName(),
    *bStr);
