The Cryptographic ALU is a special resource, used as the key component for crafting the Razorback Cipher. As such it is only available during a Razorback Armada invasion event and exclusively dropped by Corpus Archwing enemies that can be found on Jupiter and Neptune. While it does only have an uncommon drop chance it drops in quantities of 1 unit, typical of rare resources. Click to view the Blueprints requiring Cryptographic ALU.
