Amiibo Encryption Key [patched]

On September 8, 2016, the key was publicly posted to the GBAtemp forums. The reaction was seismic. Within 24 hours, the first open-source amiibo emulator, was updated to write fully valid amiibo data to blank NTAG215 chips.

Understanding how the amiibo encryption key was discovered requires looking back at the timeline of the console hacking scene. The amiibo platform first appeared on the Wii U and New Nintendo 3DS in 2014. For the first several years, its cryptography remained largely intact.

The user known as (a prominent figure in the Wii U hacking scene) managed to extract the key from a retail Wii U game binary. They didn't break AES-128 (which is unbreakable via brute force). They simply read it out of the software that had to use it. amiibo encryption key

In addition to encrypting the data so it cannot be read, Nintendo uses a Keyed-Hash Message Authentication Code (HMAC) based on the SHA-256 algorithm. When a game saves data back to the Amiibo (like updating a character's stats), it generates an HMAC signature using the encryption key.
