The existing code used PKCS5 specifications.
SP800-132 adds the following additional constraints for:
- the range of the key length.
- the minimum iteration count (1000 recommended).
- salt length (at least 128 bits).
These additional constraints may cause errors (in scrypt, and
some PKCS5 related test vectors). To disable the new
constraints use the new ctrl string "pkcs5".
For backwards compatability, the checks are only enabled by
default for fips mode.

OpenSSL_version(OPENSSL_DIR) gives you a nicely formatted string for
display, but if all you really want is the directory itself, you were
forced to parsed the string.
This introduces a new function to get diverse configuration data from
the library, OPENSSL_info(). This works the same way as
OpenSSL_version(), but has its own series of types, currently
including:
OPENSSL_INFO_CONFIG_DIR returns OPENSSLDIR
OPENSSL_INFO_ENGINES_DIR returns ENGINESDIR
OPENSSL_INFO_MODULES_DIR returns MODULESDIR
OPENSSL_INFO_DSO_EXTENSION returns DSO_EXTENSION
OPENSSL_INFO_DIR_FILENAME_SEPARATOR returns directory/filename separator
OPENSSL_INFO_LIST_SEPARATOR returns list separator
For scripting purposes, this also adds the command 'openssl info'.

Properties are a sequence of comma separated name=value pairs. A name
without a corresponding value is assumed to be a Boolean and have the
true value 'yes'. Values are either strings or numbers. Strings can be
quoted either _"_ or _'_ or unquoted (with restrictions). There are no
escape characters inside strings. Number are either decimal digits or
'0x' followed by hexidecimal digits. Numbers are represented internally
as signed sixty four bit values.
Queries on properties are a sequence comma separated conditional tests.
These take the form of name=value (equality test), name!=value (inequality
test) or name (Boolean test for truth). Queries can be parsed, compared
against a definition or merged pairwise.

This commit adds a dedicated function in `EC_METHOD` to access a modular
field inversion implementation suitable for the specifics of the
implemented curve, featuring SCA countermeasures.
The new pointer is defined as:
`int (*field_inv)(const EC_GROUP*, BIGNUM *r, const BIGNUM *a, BN_CTX*)`
and computes the multiplicative inverse of `a` in the underlying field,
storing the result in `r`.
Three implementations are included, each including specific SCA
countermeasures:
- `ec_GFp_simple_field_inv()`, featuring SCA hardening through
blinding.
- `ec_GFp_mont_field_inv()`, featuring SCA hardening through Fermat's
Little Theorem (FLT) inversion.
- `ec_GF2m_simple_field_inv()`, that uses `BN_GF2m_mod_inv()` which
already features SCA hardening through blinding.
From a security point of view, this also helps addressing a leakage
previously affecting conversions from projective to affine coordinates.
This commit also adds a new error reason code (i.e.,
`EC_R_CANNOT_INVERT`) to improve consistency between the three
implementations as all of them could fail for the same reason but
through different code paths resulting in inconsistent error stack
states.

The original 1.1.1 design was to use SSL_CB_HANDSHAKE_START and
SSL_CB_HANDSHAKE_DONE to signal start/end of a post-handshake message
exchange in TLSv1.3. Unfortunately experience has shown that this confuses
some applications who mistake it for a TLSv1.2 renegotiation. This means
that KeyUpdate messages are not handled properly.
This commit removes the use of SSL_CB_HANDSHAKE_START and
SSL_CB_HANDSHAKE_DONE to signal the start/end of a post-handshake
message exchange. Individual post-handshake messages are still signalled in
the normal way.
This is a potentially breaking change if there are any applications already
written that expect to see these TLSv1.3 events. However, without it,
KeyUpdate is not currently usable for many applications.

Previously, the API version limit was indicated with a numeric version
number. This was "natural" in the pre-3.0.0 because the version was
this simple number.
With 3.0.0, the version is divided into three separate numbers, and
it's only the major number that counts, but we still need to be able
to support pre-3.0.0 version limits.
Therefore, we allow OPENSSL_API_COMPAT to be defined with a pre-3.0.0
style numeric version number or with a simple major number, i.e. can
be defined like this for any application:
-D OPENSSL_API_COMPAT=0x10100000L
-D OPENSSL_API_COMPAT=3
Since the pre-3.0.0 numerical version numbers are high, it's easy to
distinguish between a simple major number and a pre-3.0.0 numerical
version number and to thereby support both forms at the same time.
Internally, we define the following macros depending on the value of
OPENSSL_API_COMPAT:
OPENSSL_API_0_9_8
OPENSSL_API_1_0_0
OPENSSL_API_1_1_0
OPENSSL_API_3
They indicate that functions marked for deprecation in the
corresponding major release shall not be built if defined.

We're strictly use version numbers of the form MAJOR.MINOR.PATCH.
Letter releases are things of days past.
The most central change is that we now express the version number with
three macros, one for each part of the version number:
OPENSSL_VERSION_MAJOR
OPENSSL_VERSION_MINOR
OPENSSL_VERSION_PATCH
We also provide two additional macros to express pre-release and build
metadata information (also specified in semantic versioning):
OPENSSL_VERSION_PRE_RELEASE
OPENSSL_VERSION_BUILD_METADATA
To get the library's idea of all those values, we introduce the
following functions:
unsigned int OPENSSL_version_major(void);
unsigned int OPENSSL_version_minor(void);
unsigned int OPENSSL_version_patch(void);
const char *OPENSSL_version_pre_release(void);
const char *OPENSSL_version_build_metadata(void);
Additionally, for shared library versioning (which is out of scope in
semantic versioning, but that we still need):
OPENSSL_SHLIB_VERSION
We also provide a macro that contains the release date. This is not
part of the version number, but is extra information that we want to
be able to display:
OPENSSL_RELEASE_DATE
Finally, also provide the following convenience functions:
const char *OPENSSL_version_text(void);
const char *OPENSSL_version_text_full(void);
The following macros and functions are deprecated, and while currently
existing for backward compatibility, they are expected to disappear:
OPENSSL_VERSION_NUMBER
OPENSSL_VERSION_TEXT
OPENSSL_VERSION
OpenSSL_version_num()
OpenSSL_version()
Also, this function is introduced to replace OpenSSL_version() for all
indexes except for OPENSSL_VERSION:
OPENSSL_info()
For configuration, the option 'newversion-only' is added to disable all
the macros and functions that are mentioned as deprecated above.

In pull request #4328 the seeding of the DRBG via RAND_add()/RAND_seed()
was implemented by buffering the data in a random pool where it is
picked up later by the rand_drbg_get_entropy() callback. This buffer
was limited to the size of 4096 bytes.
When a larger input was added via RAND_add() or RAND_seed() to the DRBG,
the reseeding failed, but the error returned by the DRBG was ignored
by the two calling functions, which both don't return an error code.
As a consequence, the data provided by the application was effectively
ignored.
This commit fixes the problem by a more efficient implementation which
does not copy the data in memory and by raising the buffer the size limit
to INT32_MAX (2 gigabytes). This is less than the NIST limit of 2^35 bits
but it was chosen intentionally to avoid platform dependent problems
like integer sizes and/or signed/unsigned conversion.
Additionally, the DRBG is now less permissive on errors: In addition to
pushing a message to the openssl error stack, it enters the error state,
which forces a reinstantiation on next call.
Thanks go to Dr. Falko Strenzke for reporting this issue to the
openssl-security mailing list. After internal discussion the issue
has been categorized as not being security relevant, because the DRBG
reseeds automatically and is fully functional even without additional
randomness provided by the application.
