Where is source code for AES-256 as discussed in SLAA547?

Other Parts Discussed in Thread: AES-128, SHA-256

SLAA547 gives documentation for cryptographic routines, including AES-128 and SHA-256. That note sounds like it is discussing routines that one can get from TI somehow (though it does not say so explicitly).

SLAA391 also discusses AES-128, and that document does tell one to look for AES_128.zip. That file contains source code in C for the two AES routines documented in both notes. I compiled them for the MSP430 and they work. So far so good, and thanks, TI!

SLAA547 does not say (that I can find) where to get source for any of the routines it discusses, and searching about under various likely names I find no corresponding source for SHA-256, which I also need.

Is the source code for SHA-256 available? If so, where and under what name should I look for it?

Correction: SLAA397 (not 391) discusses AES-128 and tells where to get source code for it.

Hi Phil,

Have you seen this example?

I had not seen that note, and am glad to know of it.

I was embarrassed to notice that I had written AES-256 instead of SHA-256 in the title of my original post, though I got it right in the main text.I have no idea how that happened.

It appears that I really do need SHA-256 rather than SHA-1 for the task I have in front of me. Is the source code for that available? If not, just what implementation of cryptographic primitives does SLAA547 discuss?

Bruce,

That's it! Thank you.

How does one discover such links? Is there a list anywhere?

Hello,

I was trying to download the SHA-256 algorithm from TI site to use with one of the MS430 MCU.

Link - http://www.ti.com/tool/SHA-256

When I click on download, it says page not found. How were you able to download this?

Thanks,

Gopi

Hi Gopi,

The link is broken at the moment, but using this should work in the mean time:

http://downloads.ti.com/tsu_encryption/tsu_encryption_public_sw/mcu/msp430/SHA_256/SHA_256_102612.zip

Thanks for pointing this out- we will work to fix the link.
