=head1 NAME

RSA_print, RSA_print_fp,
DSAparams_print, DSAparams_print_fp, DSA_print, DSA_print_fp,
DHparams_print, DHparams_print_fp - print cryptographic parameters

=head1 SYNOPSIS

 #include <openssl/rsa.h>

The following functions have been deprecated since OpenSSL 3.0, and can be
hidden entirely by defining B<OPENSSL_API_COMPAT> with a suitable version value,
see L<openssl_user_macros(7)>:

 int RSA_print(BIO *bp, const RSA *x, int offset);
 int RSA_print_fp(FILE *fp, const RSA *x, int offset);

 #include <openssl/dsa.h>

The following functions have been deprecated since OpenSSL 3.0, and can be
hidden entirely by defining B<OPENSSL_API_COMPAT> with a suitable version value,
see L<openssl_user_macros(7)>:

 int DSAparams_print(BIO *bp, const DSA *x);
 int DSAparams_print_fp(FILE *fp, const DSA *x);
 int DSA_print(BIO *bp, const DSA *x, int offset);
 int DSA_print_fp(FILE *fp, const DSA *x, int offset);

 #include <openssl/dh.h>

The following functions have been deprecated since OpenSSL 3.0, and can be
hidden entirely by defining B<OPENSSL_API_COMPAT> with a suitable version value,
see L<openssl_user_macros(7)>:

 int DHparams_print(BIO *bp, DH *x);
 int DHparams_print_fp(FILE *fp, const DH *x);

=head1 DESCRIPTION

All of the functions described on this page are deprecated.
Applications should instead use L<EVP_PKEY_print_params(3)> and
L<EVP_PKEY_print_private(3)>.

A human-readable hexadecimal output of the components of the RSA
key, DSA parameters or key or DH parameters is printed to B<bp> or B<fp>.

The output lines are indented by B<offset> spaces.

=head1 RETURN VALUES

DSAparams_print(), DSAparams_print_fp(), DSA_print(), and DSA_print_fp()
return 1 for success and 0 or a negative value for failure.

DHparams_print() and DHparams_print_fp() return 1 on success, 0 on error.

=head1 SEE ALSO

 L<EVP_PKEY_print_params(3)>,
 L<EVP_PKEY_print_private(3)>,
 L<BN_bn2bin(3)>

=head1 HISTORY

All of these functions were deprecated in OpenSSL 3.0.
