=head1 NAME
|
||
|
|
|
||
|
EVP_PKEY_print_public, EVP_PKEY_print_private, EVP_PKEY_print_params - public key algorithm printing routines
|
||
|
|
|
||
|
|
=head1 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);
|
||
|
|
|
||
|
|
=head1 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 B<pkey> respectively. The key is sent to BIO B<out> in human readable
|
||
|
|
form. The parameter B<indent> indicated how far the printout should be indented.
|
||
|
|
|
||
|
|
The B<pctx> parameter allows the print output to be finely tuned by using
|
||
|
|
ASN1 printing options. If B<pctx> is set to NULL then default values will
|
||
|
|
be used.
|
||
|
|
|
||
|
|
=head1 NOTES
|
||
|
|
|
||
|
|
Currently no public key algorithms include any options in the B<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.
|
||
|
|
|
||
|
|
=head1 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.
