CryptexManager

CryptexManager is an open-source replacement for cryptexctl. It supports creating, signing, installing, uninstalling and listing cryptexes.

Building

First, make sure libimobiledevice is installed (brew install libimobiledevice). Afterwards, it should be sufficient to run swift build -c release -Xlinker -L$(brew --prefix)/lib -Xcc -I$(brew --prefix)/include. The executable can then be found at .build/release/CryptexManager.

Using

For now, just run CryptexManager without arguments to see the usage.

Using in a Makefile

To use CryptexManager instead of cryptexctl in a Makefile (assuming you're using the example Makefile provided by Apple), replace the install/uninstall actions with this:

# Uninstall the cryptex from the device
.PHONY: uninstall
uninstall:
	@$(call log, Removing ${CRYPTEX_ID} from device: ${CRYPTEXCTL_UDID})
	$(call check_path, CryptexManager, "CryptexManager is not on your path. Please make sure it is installed.")
	CryptexManager -u ${CRYPTEXCTL_UDID} list
	CryptexManager -u ${CRYPTEXCTL_UDID} uninstall ${CRYPTEX_ID}
	CryptexManager -u ${CRYPTEXCTL_UDID} list

# Install the cryptex onto the device
.PHONY: install
install: ${CRYPTEX_PATH}
	@$(call log, Installing ${CRYPTEX_PATH} onto device: ${CRYPTEXCTL_UDID})
	$(call check_path, CryptexManager, "CryptexManager is not on your path. Please make sure it is installed.")
	CryptexManager -u ${CRYPTEXCTL_UDID} uninstall ${CRYPTEX_ID} || true
	CryptexManager -u ${CRYPTEXCTL_UDID} install ${CRYPTEX_PATH} || log_die "Failed to install cryptex... Is your device '${CRYPTEXCTL_UDID}' connected?" $?
	CryptexManager -u ${CRYPTEXCTL_UDID} list

Additionally, replace the create rule with this:

# Create the cryptex from the disk image containing the distribution root
${CRYPTEX_PATH}: ${CRYPTEX_DMG_NAME}
	@$(call log, Creating cryptex ${CRYPTEX_PATH} - ${CRYPTEX_VERSION} from the disk image ${CRYPTEX_DMG_NAME})
	$(call check_path, CryptexManager, "CryptexManager is not on your path. Please make sure it is installed.")
	CryptexManager -u ${CRYPTEXCTL_UDID} create -i ${CRYPTEX_ID} -v ${CRYPTEX_VERSION} ${CRYPTEX_DMG_NAME} ${CRYPTEX_ROOT_DIR} ${CRYPTEX_PATH}
