|
|
-Crack Prevention</a>: App Store binaries are signed by both their developer
|
|
|
-and Apple. This encrypts the binary so that decryption keys are needed in order
|
|
|
-to make the binary readable. When iOS executes the binary, the decryption keys
|
|
|
-are used to decrypt the binary into a readable state where it is then loaded
|
|
|
-into memory and executed. iOS can tell the encryption status of a binary via the
|
|
|
-cryptid structure member of LC_ENCRYPTION_INFO MachO load command. If cryptid is
|
|
|
-a non-zero value then the binary is encrypted.
|
|
|
-
|
|
|
-'Cracking' works by letting the kernel decrypt the binary then siphoning the
|
|
|
-decrypted data into a new binary file, resigning, and repackaging. This will
|
|
|
-only work on jailbroken devices as codesignature validation has been removed.
|
|
|
-Resigning takes place because while the codesignature doesn't have to be valid
|
|
|
-thanks to the jailbreak, it does have to be in place unless you have AppSync or
|
|
|
-similar to disable codesignature checks.
