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.
ATTRIBUTES

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