This is based on RT#3810, which added dedicated modular inversion.
ECDSA verify results improves as well, but not as much.

Removed e_os.h from all bar three headers (apps/apps.h crypto/bio/bio_lcl.h and
ssl/ssl_locl.h).
Added e_os.h into the files that need it now.
Directly reference internal/nelem.h when required.

Rename and change ED25519_keypair_from_seed to ED25519_public_from_private
to be consistent with X25519 API.
Modidy ED25519_sign to take separate public key argument instead of
requiring it to follow the private key.

Reinstate Ed25519 algorithm to curv25519.c this is largely just a copy of
the code from BoringSSL with some adjustments so it compiles under OpenSSL.

The EC code recently started using REF_PRINT_COUNT and REF_ASSERT_ISNT.
Those are defined in e_os.h.

Handle KDF in ECDH_compute_key instead of requiring each implementation
support it. This modifies the compute_key method: now it allocates and
populates a buffer containing the shared secret.

Instead of overriding a default operation move default operation to a
separate function which is then explicitly included in any EC_METHOD
that uses it.

Add a flag to EC_METHOD for curves which do not support signing.
New function EC_KEY_can_sign() returns 1 is key can be used for signing.
Return an explicit error is an attempt is made to sign with
no signing curves.

This was done by the following
find . -name '*.[ch]' | /tmp/pl
where /tmp/pl is the following three-line script:
print unless $. == 1 && m@/\* .*\.[ch] \*/@;
close ARGV if eof; # Close file to reset $.
And then some hand-editing of other files.

Add CRYPTO_EX_DATA add EndC_KEY_[gs]et_method, From Roumen Petrov.
Had to add various exdata calls to init/copy/free the exdata.
Had to remove const from some EC functions because exdata isn't
const-correct. :(
Also remove EC_EXTRA_DATA and use a union to hold the possible
pre-computed values and an enum to tell which value is in the
union. (Rich Salz)

Add set_group, set_public and set_private methods. An EC_KEY_METHOD can use
these to perform any appropriate operation when the key components are set,
such as caching data in some more convenient ENGINE specific format or
returning an error if the parameters are invalid or the operation is
not supported.

Add EC_KEY_METHOD. This is part of the EC revision and will make EC behave
more like other algorithms. Specifically:
EC_KEY_METHOD is part of EC_KEY.
It is part of ENGINE.
Default or key specific implementations can be provided to redirect some

This change updates 8a99cb29 to make the generation of (EC)DSA nonces
using the message digest the default. It also reverts the changes to
(EC)DSA_METHOD structure.
In addition to making it the default, removing the flag from EC_KEY
means that FIPS modules will no longer have an ABI mismatch.
|
|
This change adds the option to calculate (EC)DSA nonces by hashing the
message and private key along with entropy to avoid leaking the private
key if the PRNG fails.

Also, use the common Configure mechanism for enabling/disabling the 64-bit ECC code.

Move compression, point2oct and oct2point functions into separate files.
Add a flags field to EC_METHOD.
Add a flag EC_FLAGS_DEFAULT_OCT to use the default compession and oct
functions (all existing methods do this). This removes dependencies from
EC_METHOD while keeping original functionality.
