Algorithms ---------- In principle any suitable algorithm can be used to sign and verify a hash. -At present only one class of algorithms is supported: SHA1 hashing with RSA. -This works by hashing the image to produce a 20-byte hash. +U-Boot supports a few hashing and verification algorithms. See below for +details. While it is acceptable to bring in large cryptographic libraries such as openssl on the host side (e.g. mkimage), it is not desirable for U-Boot.
U-Boot supports more hash and verification algorithms these days. Signed-off-by: Baruch Siach <baruch@tkos.co.il> --- doc/uImage.FIT/signature.txt | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-)
