commit 96ebe52e897dea29664683e138877fb5eb995e4d
Author: Shane Lontis <shane.lontis at oracle.com>
Date: Wed Apr 1 15:51:18 2020 +1000
Add EVP_PKEY_gettable_params support for accessing EVP_PKEY key data fields
Currently only RSA, EC and ECX are supported (DH and DSA need to be added to the keygen
PR's seperately because the fields supported have changed significantly).
The API's require the keys to be provider based.
Made the keymanagement export and get_params functions share the same code by supplying
support functions that work for both a OSSL_PARAM_BLD as well as a OSSL_PARAM[].
This approach means that complex code is not required to build an
empty OSSL_PARAM[] with the correct sized fields before then doing a second
pass to populate the array.
The RSA factor arrays have been changed to use unique key names to simplify the interface
needed by the user.

+EVP_PKEY_gettable_params() returns a constant list of I<params> indicating
+the names and types of key parameters that can be retrieved.
+See L<OSSL_PARAM(3)> for information about parameters.
+
+EVP_PKEY_get_int_param() retrieves a key I<pkey> integer value I<*out>
+associated with a name of I<key_name>.
+
+EVP_PKEY_get_size_t_param() retrieves a key I<pkey> size_t value I<*out>
+associated with a name of I<key_name>.
+
+EVP_PKEY_get_bn_param() retrieves a key I<pkey> BIGNUM value I<**bn>
+associated with a name of I<key_name>. If I<*bn> is NULL then the BIGNUM
+is allocated by the method.
+
+EVP_PKEY_get_utf8_string_param() get a key I<pkey> UTF8 string value int a buffer
+I<str> of maximum size I<max_buf_sz> associated with a name of I<key_name>.
+I<*out_sz> is the returned size of the string if it is not NULL.
+
+EVP_PKEY_get_octet_string_param() copy a I<pkey>'s octet string value into a buffer
+I<buf> of maximum size I<max_buf_sz> associated with a name of I<key_name>.
+I<*out_sz> is the returned size of the buffer if it is not NULL.
+
+=head1 NOTES
+
+These functions only work for B<EVP_PKEY>s that contain a provider side key.
+
+=head1 RETURN VALUES
+
+EVP_PKEY_gettable_params() returns NULL on error or if it is not supported,
+
+All other methods return 1 if a value associated with the key's I<key_name> was
+successfully returned, or 0 if there was an error.
+An error may be returned by methods EVP_PKEY_get_utf8_string_param() and
+EVP_PKEY_get_octet_string_param() if I<max_buf_sz> is not big enough to hold the
+value.
+

+ char *curve_name[64];
+ unsigned char pub[256];
+ BIGNUM *bn_priv = NULL;
+
+ /*
+ * NB: assumes 'key' is set up before the next step. In this example the key
