Currently imgtool --verify fails for hex files with:
Invalid image magic; is this an MCUboot image?
Added support for hex files by converting hex to bin
using IntelHex::tobinstr().
Reusing image.load() needs a bit of rework, maybe a
common load method will be done in the future,

The IMAGE_TLV_ECDSA256 TLV has been put out of use by
commit 63d2346da4.
This commit reverts this part of that patch and at the
same time it extends the usage of this TLV to cover all types
of curves (replacing the newly introduced 0x25 TLV type)
while retaining its value (0x22) for backward compatibility.
Rename IMAGE_TLV_ECDSA256 to IMAGE_TLV_ECDSA_SIG.

The TLV type field in trailer TLV struct is defined as unsigned 16-bit
(in LE byte order). Currently, due to Python's struct format specified
as 'BBH', the 'imgtool' accepts only single byte for this field.
This results in error when trying to use 16-bit TLV type with option
'--custom-tlv':
struct.error: ubyte format requires 0 <= number <= 255
This changes format to 'HH' which allows using 16-bit TLV types and
while at it, adds also simple range validation for custom TLV type.
As defined in image.h header, the vendor reserved TLVs value should
be from 0x00a0 to 0xfffe range.

Verify mode already works for the public halves of RSA and ECDSA keypairs.
This patch corrects an apparent oversight, enabling that functionality
in Ed25519.
Signed-off-by: Ross Younger <crazyscot@gmail.com>
A previous change was added to allow the `getpriv` command to dump ec256
keys in both openssl and pkcs8. That PR did not touch other key file
types which resulted in errors using that command with RSA, X25519, etc.
This commit generalizes the passing of the `format` parameter, so each
key type can decide which format it allows a dump to be produced in,
and what default to use.

`--vector-to-sign` only exports the image payload, or digest, to be

This patch improves the existing ECDSA key generation feature
in the imgtool by:
- Fix a bug in the 'minimal' representation of PKCS#8 keys where
the resulting ASN.1 DER encoding is not compliant
- Add the option to export ECDSA private keys in SEC1 format by
providing a command line option -f or --format that can be
'openssl' (for SEC1 format) or 'pkcs8'. This format ends up in
key encodings which are generally smaller than PKCS#8.

Update a previous PR were PEM exporting was added to the `--lang`
parameter, even though PEM is not a source code language per se.
This PR adds `--encoding/-e` to `getpub` command, for exporting
in formats other than a language source code. `--lang` is left with
a deprecation message, so it could be removed in a future version.
The default behavior of exporting source code in C was preserved.

Update `getpub` with new `lang` option, "pem", which allows exporting a

When generating an image with trailer (--pad or --confirm), the
imgtool also adds the erased values into that area. This is not
wanted for flash drivers which use ECC and treat writing erased
values as a real write action, which cannot be overwritten anymore.

The value of `--max-align` parameter passed to imgtool can never be
less than the value of `--align` parameter. At present the default
value of `--max-align` is fixed at 8. This forces user to pass the
parameter even when its value can be safely inferred.
Change the default value of the `--max-align` parameter to the larger
of the two values: `--align` or 8. Consequently, the user is required
to pass the parameter only if the flash alignment of the primary and
secondary slot differ.
