Migrate to OpenSSL 3.0 in advance of FreeBSD 14.0. OpenSSL 1.1.1 (the version we were previously using) will be EOL as of 2023-09-11. Most of the base system has already been updated for a seamless switch to OpenSSL 3.0. For many components we've added `-DOPENSSL_API_COMPAT=0x10100000L` to CFLAGS to specify the API version, which avoids deprecation warnings from OpenSSL 3.0. Changes have also been made to avoid OpenSSL APIs that were already deprecated in OpenSSL 1.1.1. The process of updating to contemporary APIs can continue after this merge. Additional changes are still required for libarchive and Kerberos- related libraries or tools; workarounds will immediately follow this commit. Fixes are in progress in the upstream projects and will be incorporated when those are next updated. There are some performance regressions in benchmarks (certain tests in `openssl speed`) and in some OpenSSL consumers in ports (e.g. haproxy). Investigation will continue for these. Netflix's testing showed no functional regression and a rather small, albeit statistically significant, increase in CPU consumption with OpenSSL 3.0. Thanks to ngie@ and des@ for updating base system components, to antoine@ and bofh@ for ports exp-runs and port fixes/workarounds, and to Netflix and everyone who tested prior to commit or contributed to this update in other ways.

=head1 NAME
|
|
|
|
RSA_new, RSA_free - allocate and free RSA objects
|
|
|
|
=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)>:
|
|
|
|
RSA *RSA_new(void);
|
|
|
|
void RSA_free(RSA *rsa);
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
RSA_new() allocates and initializes an B<RSA> structure. It is equivalent to
|
|
calling RSA_new_method(NULL).
|
|
|
|
RSA_free() frees the B<RSA> structure and its components. The key is
|
|
erased before the memory is returned to the system.
|
|
If B<rsa> is NULL nothing is done.
|
|
|
|
=head1 RETURN VALUES
|
|
|
|
If the allocation fails, RSA_new() returns B<NULL> and sets an error
|
|
code that can be obtained by L<ERR_get_error(3)>. Otherwise it returns
|
|
a pointer to the newly allocated structure.
|
|
|
|
RSA_free() returns no value.

=head1 HISTORY
|
|
|
|
All functions described here were deprecated in OpenSSL 3.0.

For replacement see EVP_PKEY-RSA(7).
