Since we use Crypto++ anyway, we might as well get use a good implementation. Change-Id: I761ad7401653471e54000e1c2bc3d9882378112f

imxtools/sbtools: switch AES implementation to Crypto++ 2017-01-16T18:59:26+00:00 Amaury Pouly amaury.pouly@gmail.com 2017-01-03T12:56:48+00:00 8b3f5a8ad7434850804a4a664d2b07c6ffa9b1c7 Instead of having our own copy of the AES code, use a good library to do that. Crypto++ is well-maintained, supports a lot of ciphers, works on many OSes, and is optimized for many architectures. Change-Id: I7d7d24b47993206d7338c5f9bac8bbdd3915a667

imxtools/sbtools: rework cryptography 2017-01-16T18:58:24+00:00 Amaury Pouly amaury.pouly@gmail.com 2017-01-01T19:48:05+00:00 2b20026dd755706934f8f8e1a192bffdfc3d717c It was a mess, a mix of crypto_* and cbc_mac calls. I made everything call crypto functions, and also separate key setup from cryptographic operations, this will be useful to speed up the code in the upcoming commits. Drop support for "usbotp" key, since the crypto code for that was never mainlined and we can always get the keys from a device as long as we have code execution (using the DCP debug registers).

sbtools: add brute force option for sb1 in sbtoelf 2013-02-16T19:49:07+00:00 Amaury Pouly amaury.pouly@gmail.com 2013-02-16T19:47:07+00:00 b05b762ed45c6c8967fce098c598ec1a6ed7a533 After some reverse engineering, it appears that the keys of the sb1 format are very weak: the 128 bytes are generated from the laserfuse words 4,5 and 6 but in a weird manner: 4 and 5 are simply ORed and 6 is only half used (somehow), making it "only" a 48 bit word to find.

sbtools: add support for the stmp36xx format 2012-11-26T22:58:30+00:00 Amaury Pouly amaury.pouly@gmail.com 2012-11-26T22:54:44+00:00 4e95b72ecbd972b9e1eb162c40a559b94eebac69 The STMP36xx series also uses .sb files but with a different format. The main differences are the encryption and the lack of sections, making it basically a list of commands: fill, load, call, jump, switch mode, set sdram settings. Currently only the sbtoelf has support for the sb1 and can only dump the list of commands. Actual support for elf creation will come later. Change-Id: I1f2e0230c91ac64efd0e8430e0c5212098c599fd
