EVP_PKEY_PRINT_PRIVATE(3)	    OpenSSL	     EVP_PKEY_PRINT_PRIVATE(3)

NAME
       EVP_PKEY_print_public, EVP_PKEY_print_private, EVP_PKEY_print_params -
       public key algorithm printing routines

SYNOPSIS
	#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);

DESCRIPTION
       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.

NOTES
       Currently no public key algorithms include any options in the pctx
       parameter.

       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.

RETURN VALUES
       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)

HISTORY
       These functions were added in OpenSSL 1.0.0.
