The srp application created an uninitialised DB_ATTR object and then
passed it to the load_index function which attempted to read it. A
DB_ATTR object only contains a single field called "unique_subject".
AFAICT this attribute is unused in the SRP case, and therefore it would be
better to pass a NULL DB_ATTR to load_index (which handles that case
gracefully).

We should only copy parameters and keys if the group is set. Otherwise
they don't really make any sense. Previously we copied the private key
regardless of whether the group was set...but if it wasn't a NULL ptr
deref could occur. It's unclear whether we could ever get into that
situation, but since we were already checking it for the public key we
should be consistent.

The non-ascii version of this set of macros ensures that the "a" variable
is inside the expected range. This logic wasn't quite right for the

Building with -DCHARSET_EBCDIC and using --strict-warnings resulted in

When compiling all other C files, rely on the compiler to
automatically pick up the name translation information from the header
files __DECC_INCLUDE_{PRO,EPI}LOGUE.H.
Reviewed-by: Andy Polyakov <appro@openssl.org>
With DEC C on VMS, you can use __DECC_INCLUDE_PROLOGUE.H and
__DECC_INCLUDE_EPILOGUE.H to include some DEC C specific features or
pragmas without having to touch the other header files.
It seems, however, that the current version of the compiler requires
the file names to be upcased, or it doesn't handle them quite right.

Currently we can get all block ciphers with
EVP_get_cipherbyname("<alg_name>-<block-mode-name>")
for example, by names "aes-128-ecb" or "des-ede-cbc".
I found a problem with des-ede-ecb and des-ede3-ecb ciphers as
they can be accessed only with names:
EVP_get_cipherbyname("des-ede")
EVP_get_cipherbyname("des-ede3")
It breaks the general concept.
In this patch I add aliases which allow to use names:
EVP_get_cipherbyname("des-ede-ecb")
EVP_get_cipherbyname("des-ede3-ecb")
in addition to the currently used names.

The tls_client_key_exchange_post_work() frees the pms on error. It also
calls ssl_generate_master_secret() which also free the pms. If an error
occurs after ssl_generate_master_secret() has been called then a double

OpenSSL 1.1.0-pre5 has made some additional structs opaque. Python's ssl
module requires access to some of the struct members. Three new getters
are added:
int X509_OBJECT_get_type(X509_OBJECT *a);
STACK_OF(X509_OBJECT) *X509_STORE_get0_objects(X509_STORE *v);
X509_VERIFY_PARAM *X509_STORE_get0_param(X509_STORE *ctx);
