To decode a key with type B<EVP_PKEY_EC>, d2i_PublicKey() requires B<*a> to be

a non-NULL EVP_PKEY structure assigned an EC_KEY structure referencing the proper

EC_GROUP.

d2i_PrivateKey() and d2i_AutoPrivateKey() return a valid B<EVP_KEY> structure

or B<NULL> if an error occurs. The error code can be obtained by calling

L<ERR_get_error(3)>.

The d2i_PrivateKey(), d2i_AutoPrivateKey(), d2i_PrivateKey_bio(), d2i_PrivateKey_fp(),

and d2i_PublicKey() functions return a valid B<EVP_KEY> structure or B<NULL> if an

error occurs. The error code can be obtained by calling L<ERR_get_error(3)>.



i2d_PrivateKey() returns the number of bytes successfully encoded or a

negative value if an error occurs. The error code can be obtained by calling
