hash: Add function to find hash_algo struct with progressive hash

2015-01-30T00:09:59+00:00

The hash_algo structure has some implementations in which progressive hash
API's are not defined. These are basically the hardware based implementations
of SHA. An API is added to find the algo which has progressive hash API's
defined. This can then be integrated with RSA checksum library which uses
Progressive Hash API's.

hash: Use uint8_t in preference to u8

2014-06-19T15:18:55+00:00

This type is more readily available on the host compiler, so use it instead.

hash: Export the function to show a hash

2014-06-11T20:25:46+00:00

This function is useful for displaying a hash value, so export it.

Prevent a buffer overflow in mkimage when signing with SHA256

2014-06-05T21:01:23+00:00

Due to the FIT_MAX_HASH_LEN constant not having been updated
to support SHA256 signatures one will always see a buffer
overflow in fit_image_process_hash when signing images that
use this larger hash.  This is exposed by vboot_test.sh.

gen: Add progressive hash API

2014-03-21T20:39:36+00:00

Add hash_init(), hash_update() and hash_finish() to the
hash_algo struct. Add hash_lookup_algo() to look up the
struct given an algorithm name.

hash: Add a way to calculate a hash for any algortihm

2013-05-14T19:37:24+00:00

Rather than needing to call one of many hashing algorithms in U-Boot,
provide a function hash_block() which handles this, and can support all
available hash algorithms.

Once we have md5 supported within hashing, we can use this function in
the FIT image code.

hash: Use lower case for hash algorithm names

2013-03-01T03:49:13+00:00

Rather than use strcasecmp() in the hash algorithm search, require the
caller to do this first. Most of U-Boot can use lower case anyway, and
the hash command can convert to lower case before calling hash_command().
This saves needing strcasecmp() for boards that use hashing but not
the hash command.

Roll crc32 into hash infrastructure

2013-03-01T03:09:23+00:00

Add the CRC32 algorithm to the list of available hashes, and make
the crc32 command use hash_command(). Add a new crc32_wd_buf() to
make this possible, which puts its result in a buffer rather than
returning it as a 32-bit value.

Note: For some boards the hash command is not enabled, neither
are sha1, sha256 or the verify option. In this case the full
hash implementation adds about 500 bytes of overhead. So as a
special case, we use #ifdef to select very simple bahaviour in
that case. The justification for this is that it is currently
a very common case (virtually all boards enable crc32 but only
some enable more advanced features).
