The EVP_PKEY_CTX_set_ec_paramgen_curve_nid() sets the EC curve for EC parameter
generation to B<nid>. For EC parameter generation this macro must be called
-or an error occurs because there is no default curve. In OpenSSL 1.0.2 and
-later this function can also be called to set the curve explicitly when
+or an error occurs because there is no default curve.
+This function can also be called to set the curve explicitly when
generating an EC key.
The EVP_PKEY_CTX_set_ec_param_enc() sets the EC parameter encoding to
B<OPENSSL_EC_EXPLICIT_CURVE> for explicit parameters (the default in versions
of OpenSSL before 1.1.0) or B<OPENSSL_EC_NAMED_CURVE> to use named curve form.
For maximum compatibility the named curve form should be used. Note: the
-B<OPENSSL_EC_NAMED_CURVE> value was only added to OpenSSL 1.1.0: previous
+B<OPENSSL_EC_NAMED_CURVE> value was only added to OpenSSL 1.1.0; previous
versions should use 0 instead.
