b6358c89a1 Convert openssl code not to assume the deprecated form of BN_zero().
Remove certain redundant BN_zero() initialisations, because BN_CTX_get(),
BN_init(), [etc] already initialise to zero.

Correct error checking in bn_sqr.c, and be less wishy-wash about how/why
the result's 'top' value is set (note also, 'max' is always > 0 at this
point).

37af03d311 General improvements to the ec_asn1.c code. This squashes at least one bug
(where it was impossible to create an EC certificate with a compressed
public key), and has some style improvements based on some comments from
Steve Henson about use of the ASN1 macros.

f2aa055ec6 treat 'out' like i2d functions do; cf. asn1_item_flags_i2d (crypto/asn/tasn_enc.c) 2003-02-21 16:06:39 +00:00

62e3163b1b ECPublicKey_set_octet_string and ECPublicKey_get_octet_string
behaviour was not quite consistent with the conventions
for d2i and i2d functions as far as handling of the 'out'
or 'in' pointer is concerned.

This patch changes this behaviour, and renames the functions to
o2i_ECPublicKey and i2o_ECPublicKey (not 'd2i' and 'i2d' because the
external encoding is just a raw object string without any DER icing).

ba729265a8 Allow EC_GROUP objects to share precomputation for improved memory
efficiency (EC_PRE_COMP objects are now constant once completed).

Extend 'extra_data' API to support arbitrarily many slots (although we
need only one at the moment).

Modify EC internal 'extra_data' API: EC_GROUP_[clear_]free_extra_data
now frees only a single slot (the previous functions are available as
EC_GROUP_[clear_]free_all_extra_data).

d745af4b0c avoid potential confusion about curves (prime192v1 and prime256v1 are

e9224c7177 This is a first-cut at improving the callback mechanisms used in
key-generation and prime-checking functions. Rather than explicitly passing
callback functions and caller-defined context data for the callbacks, a new
structure BN_GENCB is defined that encapsulates this; a pointer to the
structure is passed to all such functions instead.

This wrapper structure allows the encapsulation of "old" and "new" style
callbacks - "new" callbacks return a boolean result on the understanding
that returning FALSE should terminate keygen/primality processing.  The
BN_GENCB abstraction will allow future callback modifications without
needing to break binary compatibility nor change the API function
prototypes. The new API functions have been given names ending in "_ex" and
the old functions are implemented as wrappers to the new ones.  The
OPENSSL_NO_DEPRECATED symbol has been introduced so that, if defined,
declaration of the older functions will be skipped. NB: Some
openssl-internal code will stick with the older callbacks for now, so
appropriate "#undef" logic will be put in place - this is in case the user
is *building* openssl (rather than *including* its headers) with this
symbol defined.

There is another change in the new _ex functions; the key-generation
functions do not return key structures but operate on structures passed by
the caller, the return value is a boolean. This will allow for a smoother
transition to having key-generation as "virtual function" in the various
***_METHOD tables.

projective coordinates, and if it did, it would not use Jacobian
projective coordinates; so it's OK to use the ..._GFp prefix for all
this.

79aa04ef27 Make the necessary changes to work with the recent "ex_data" overhaul.
See the commit log message for that for more information.

NB: X509_STORE_CTX's use of "ex_data" support was actually misimplemented
(initialisation by "memset" won't/can't/doesn't work). This fixes that but
requires that X509_STORE_CTX_init() be able to handle errors - so its
prototype has been changed to return 'int' rather than 'void'. All uses of
that function throughout the source code have been tracked down and
adjusted.

the term "simultaneous multiplication" (which -- acording to the
paper, at least -- applies only to certain methods which we don't use
here)

4f69172d25 Completely remove mont2 stuff.
It does not appear to be faster than the current Montgomery code
except for very small moduli (somewhere between 192 and 224 bits
in a 64-bit Sun environment, and even less than 192 bits
on 32 bit systems).
