Subject: Is RSA algorithm support for the software authentication in u-boot?

Hi ,
        I am looking for the RSA , public key authentication  for the images like u-boot.img ,uImage from the u-boot. In u-boot already  support for the SHA1 and md5,that's great!!!. But I want to use RSA algorithm for more security and official firmware releases.
Is there any support for that in u-boot?.  Or we have to integrate it.?
Please gives us the suggestions...

Surendra.

Basically, you want to not only prevent software corruption, but lock down the 
device? Why ...

But either way, yes, you'd have to implement support for RSA into uboot.

The stuff below is nonsense and it takes half of the space in this email, can 
you please fix it?
