0x0 | 0x10 | AES-CBC MAC over a SHA256 hash, which hashes the first 0x110-bytes of the cleartext SEED. |
0x10 | 0x120 | The nand/private/movable.sed, encrypted with AES-CTR using the above MAC for the counter. |
Description
This decrypts the input SEED and verifies it with the input AES-CBC MAC, verifies the RSA-signature, then writes the data to nand/private/movable.sed.
