Is there a way to verify client-side mods from server-side by using JAR signing?

I have a client-side mod and a server-side mod. I want to make sure that the client has the correct mod file (making sure it's not modified), by using JAR signing and stuff. Is there a way to be able to do this via the server-side mod? I saw something in @Mod that looked something like a certificate fingerprint, so I got curious.

    • I did download the latest forge-1.18-38.0.6-installer and installed it correctly into the right place. Also downloaded  38.0.5 to test (didn't work) and downloaded 38.0.0 None of those worked.
    • Unknown module securejarhandler implies that some libraries were missed during the installation. I suggest you redownload the latest installer and run it again.
    • Forge Version: 38.0.6 Minecraft Version: 1.18 Downloads: Changelog: (Direct) Installer: (AdFocus) (Direct) MDK: (AdFocus) (Direct) However, as this is the start of a new version, it is recommended that you check the Downloads Page and use the latest version to receive any bug fixes. Intro: 1.17 was a stepping stone, and 1.18 is the real target. The culmination of the Caves & Cliffs update, with few real code changes from 1.17 except those required to plug in the new biome system. This is our new Latest version. As we had some time before the release, we handled some refactors beforehand. Those will be listed here. Changelog: Refactors (not comprehensive): 99% of the fmllegacy package. Most classes were simply moved from x.y.fmllegacy.z to x.y.z. All instances of Gui -> Screen (GuiOpenEvent -> ScreenOpenEvent, for example) GuiScreenEvent -> ScreenEvent, GuiOverlayDebugForge -> ForgeDebugScreenOverlay All instances of GameMode -> GameType (ClientPlayerChangeGameModeEvent -> ClientPlayerChangedGameTypeEvent, for example) All instances of MatrixStack -> PoseStack (DrawSelectionEvent.matrix -> DrawSelectionEvent.poseStack, for example All instances of KeyBinding -> KeyMapping (ClickInputEvent.keyBinding -> ClickInputEvent.keyMapping, for example All instances of World -> Level All instances of WorldType -> WorldPreset (ForgeHooksClient.getDefaultWorldType -> ForgeHooksClient.getDefaultWorldPreset, for example All instances of NBT -> Tag (BlockSnapshot.getNbt -> BlockSnapshot.getTag, for example) All instances of Container -> Menu (IForgeContainerType -> IForgeMenuType, for example) PlaySoundEvent.sound -> PlaySoundEvent.originalSound PlaySoundEvent.result -> PlaySoundEvent.sound SoundEvent.manager -> SoundEvent.engine SoundEvent.SoundSourceEvent.source -> SoundEvent.SoundSourceEvent.channel FOVUpdateEvent -> FOVModifierEvent EntityViewRenderEvent.FOVModiier -> EntityViewRenderEvent.FieldOfView InputUpdateEvent -> MovementInputUpdateEvent InitScreenEvent.{...Widget...} -> {...Listener...} ForgeItemTagsProvider.func_240521_a_Colored -> copyColored MobSpawnInfoBuilder -> MobSpawnSettingBuilder BasicTrade -> BasicItemListing ModelLoader -> ForgeModelBakery ForgeWorldTypeScreens -> ForgeWorldPresetEditors StackList -> MultItemValue Removals: Entire Animation API IForgeTextureAtlasSprite IForgeItem.{showDurabiityBar, getDurabilityForDisplay, getRGBDurabilityForDisplay} ForgeHooksClient.refreshResources ModelBuilder.gui3d BlockInfo.{updateShift, getShx, getShy, getShz} CapabilityInject CapabilityManager.register ConditionalAdvancement.processConditions IForgeItem.isShield IForgeStructureFeature.{getDefaultSpawnList, getDefaultCreatureSpawnList} Forge's Constants class VanillaResourceType ForgeHooksClient.worldRenderPass (+ accessor) ForgeHooksClient.{preDraw, postDraw, getColorIndex} ScrollPanel.drawBackground Screen.{RenderToolTip, RenderComponentToolTip} ResourceManager.getResourceType LootPool.bonusRolls ForgeConfig - selectiveResourceReload PotionEvent.PotionAddedEvent ClientHooks ModFileResourcePack ResourcePackLoader.getResourcePackFor ResourcePackLoader.IPackInfoFinder ServerLifecycleHooks.buildPackFinder IResourceType ReloadRequirements CommandSetDimension
