       EVP_PKEY_print_public, EVP_PKEY_print_private, EVP_PKEY_print_params -
       public key algorithm printing routines

        #include <openssl/evp.h>

        int EVP_PKEY_print_public(BIO *out, const EVP_PKEY *pkey,
                                  int indent, ASN1_PCTX *pctx);
        int EVP_PKEY_print_private(BIO *out, const EVP_PKEY *pkey,
                                   int indent, ASN1_PCTX *pctx);
        int EVP_PKEY_print_params(BIO *out, const EVP_PKEY *pkey,
                                  int indent, ASN1_PCTX *pctx);

       The functions EVP_PKEY_print_public(), EVP_PKEY_print_private() and
       EVP_PKEY_print_params() print out the public, private or parameter
       components of key pkey respectively. The key is sent to BIO out in
       human readable form. The parameter indent indicated how far the
       printout should be indented.

       The pctx parameter allows the print output to be finely tuned by using
       ASN1 printing options. If pctx is set to NULL then default values will
       be used.

       Currently no public key algorithms include any options in the pctx

       If the key does not include all the components indicated by the
       function then only those contained in the key will be printed. For
       example passing a public key to EVP_PKEY_print_private() will only
       print the public components.

       These functions all return 1 for success and 0 or a negative value for
       failure.  In particular a return value of -2 indicates the operation is
       not supported by the public key algorithm.

       EVP_PKEY_CTX_new(3), EVP_PKEY_keygen(3)

       These functions were added in OpenSSL 1.0.0.
