u-boot.git/common/cmd_hash.c, branch v2013.01 Unnamed repository; edit this file 'description' to name the repository. Add hash command to perform hashing using various algorithms 2012-12-11T20:17:34+00:00 Simon Glass sjg@chromium.org 2012-12-05T14:46:38+00:00 bf36c5d521c17460553e39d82232a51273b83aed This new command supports hashing SHA1 and SHA256. It could be extended to others such as MD5 and the CRC algorithms. The syntax is modeled on those: hash <algorithm> <address> <length> [*<dest_addr> | <dest_envvar>] to calculate a hash, and: hash -v <algorithm> <address> <length> [*<verify_addr> | <verify_envvar>] to verify a hash. Use CONFIG_CMD_HASH to enable the command, CONFIG_SHA1 to enable SHA1 and CONFIG_SHA256 to enable SHA256. The existing sha1sum command remains. Signed-off-by: Simon Glass <sjg@chromium.org> 
This new command supports hashing SHA1 and SHA256. It could be extended
to others such as MD5 and the CRC algorithms. The syntax is modeled on
those:

   hash <algorithm> <address> <length> [*<dest_addr> | <dest_envvar>]

to calculate a hash, and:

   hash -v <algorithm> <address> <length> [*<verify_addr> | <verify_envvar>]

to verify a hash.

Use CONFIG_CMD_HASH to enable the command, CONFIG_SHA1 to enable SHA1 and
CONFIG_SHA256 to enable SHA256.

The existing sha1sum command remains.
