Changes between 1.1.1 and 3.0.0 [xx XXX xxxx]
*) Change the default RSA, DSA and DH size to 2048 bit instead of 1024.
This changes the size when using the genpkey app when no size is given. It
fixes an omission in earlier changes that changed all RSA, DSA and DH
generation apps to use 2048 bits by default.
[Kurt Roeckx]
*) Added command 'openssl kdf' that uses the EVP_KDF API.

NOTES FOR VALGRIND
==================
Valgrind is a test harness that includes many tools such as memcheck,
which is commonly used to check for memory leaks, etc. The default tool
run by Valgrind is memcheck. There are other tools available, but this
will focus on memcheck.
Valgrind runs programs in a virtual machine, this means OpenSSL unit
tests run under Valgrind will take longer than normal.
Requirements
------------
1. Platform supported by Valgrind
See: http://valgrind.org/info/platforms.html
2. Valgrind installed on the platform
See: http://valgrind.org/downloads/current.html
3. OpensSSL compiled
See: INSTALL
Running Tests
-------------
Test behavior can be modified by adjusting environment variables.
EXE_SHELL
This variable is used to specify the shell used to execute OpenSSL test
programs. The default program (util/shlib_wrap.sh) initializes the
environment to allow programs to find shared libraries. The variable can
be modified to specify a different executable environment.
EXE_SHELL="`/bin/pwd`/util/shlib_wrap.sh valgrind --error-exitcode=1 --leak-check=full -q"
This will start up Valgrind with the default checker (memcheck).
The --error-exitcode=1 option specifies that Valgrind should exit with an
error code of 1 when memory leaks occur.
The --leak-check=full option specifies extensive memory checking.
The -q option prints only error messages.
Additional Valgrind options may be added to the EXE_SHELL variable.
OPENSSL_ia32cap
This variable controls the processor-specific code on Intel processors.
By default, OpenSSL will attempt to figure out the capabilities of a
processor, and use it to its fullest capability. This variable can be
used to control what capabilities OpenSSL uses.
As of valgrind-3.15.0 on Linux/x86_64, instructions up to AVX2 are
supported. Setting the following disables instructions beyond AVX2:
OPENSSL_ia32cap=":0"
This variable may need to be set to something different based on the
processor and Valgrind version you are running tests on. More information
may be found in docs/man3/OPENSSL_ia32cap.pod.
Additional variables (i.e. VERBOSE and TESTS) are described in the
INSTALL file in the root of the OpenSSL source tree.
Example command line:
make test EXE_SHELL="`/bin/pwd`/util/shlib_wrap.sh valgrind --error-exitcode=1 --leak-check=full -q" OPENSSL_ia32cap=":0"
If an error occurs, you can then run the specific test via the TESTS
variable with the VERBOSE option to gather additional information.
make test VERBOSE=1 TESTS=test_test EXE_SHELL="`/bin/pwd`/util/shlib_wrap.sh valgrind --error-exitcode=1 --leak-check=full -q" OPENSSL_ia32cap=":0"

OPENSSL_CTX_METHOD must be defined and given in the C<meth> parameter. The index
for it should be defined in cryptlib.h. The functions through the method are
used to create or free items that are stored at that index whenever a library
context is created or freed, meaning that the code that use a data item of that
index doesn't have to worry about that, just use the data available.
Deallocation of an index happens automatically when the library

Any resources allocated via a run once initialisation routine can be cleaned up

routines are called.

A B<OSSL_NAMEMAP> is a simple number E<lt>-E<gt> name map, which can
be used to give any arbitrary name (any string) a unique dynamic
identity that is valid throughout the lifetime of the associated
library context.
ossl_namemap_new() and ossl_namemap_free() construct and destruct a
new B<OSSL_NAMEMAP>.
This is suitable to use when the B<OSSL_NAMEMAP> is embedded in other
structures, or should be independent for any reason.
ossl_namemap_stored() finds or auto-creates the default namemap in the
given library context.
The returned B<OSSL_NAMEMAP> can't be destructed using
ossl_namemap_free().
ossl_namemap_add() adds a new name to the namemap if it's not already
present.
ossl_namemap_name() finds the name corresponding to the given number.
ossl_namemap_number() finds the number corresponding to the given
name.
=head1 RETURN VALUES
ossl_namemap_new() and ossl_namemap_stored() return the pointer to a
B<OSSL_NAMEMAP>, or NULL on error.
ossl_namemap_add() returns the number associated with the added
string, or zero on error.
ossl_namemap_name() returns a pointer to the name corresponding to the
given number, or NULL if it's undefined in the given B<OSSL_NAMEMAP>.

SSL_sendfile() writes B<size> bytes from offset B<offset> in the file
descriptor B<fd> to the specified SSL connection B<s>. This function provides
efficient zero-copy semantics. SSL_sendfile() is available only when
Kernel TLS is enabled, which can be checked by calling BIO_get_ktls_send().
It is provided here to allow users to maintain the same interface.
The meaning of B<flags> is platform dependent.
Currently, under Linux it is ignored.

For SSL_sendfile(), the following return values can occur:
=over 4
=item Z<>>= 0
The write operation was successful, the return value is the number
of bytes of the file written to the TLS/SSL connection.
=item E<lt> 0
The write operation was not successful, because either the connection was
closed, an error occured or action must be taken by the calling process.
Call SSL_get_error() with the return value to find out the reason.
