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.

|
|
|
|
CMS_EncryptedData_encrypt_ex, CMS_EncryptedData_encrypt
|
|
- Create CMS EncryptedData
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
#include <openssl/cms.h>
|
|
|
|
CMS_ContentInfo *CMS_EncryptedData_encrypt_ex(BIO *in,
|
|
const EVP_CIPHER *cipher,
|
|
const unsigned char *key,
|
|
size_t keylen,
|
|
unsigned int flags,
|
|
OSSL_LIB_CTX *ctx,
|
|
const char *propq);
|
|
|
|
CMS_ContentInfo *CMS_EncryptedData_encrypt(BIO *in,
|
|
const EVP_CIPHER *cipher, const unsigned char *key, size_t keylen,
|
|
unsigned int flags);
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
CMS_EncryptedData_encrypt_ex() creates a B<CMS_ContentInfo> structure
|
|
with a type B<NID_pkcs7_encrypted>. I<in> is a BIO containing the data to
|
|
encrypt using I<cipher> and the encryption key I<key> of size I<keylen> bytes.
|
|
The library context I<libctx> and the property query I<propq> are used when
|
|
retrieving algorithms from providers. I<flags> is a set of optional flags.
|
|
|
|
The I<flags> field supports the options B<CMS_DETACHED>, B<CMS_STREAM> and
|
|
B<CMS_PARTIAL>. Internally CMS_final() is called unless B<CMS_STREAM> and/or
|
|
B<CMS_PARTIAL> is specified.
|
|
|
|
The algorithm passed in the I<cipher> parameter must support ASN1 encoding of
|
|
its parameters.
|
|
|
|
The B<CMS_ContentInfo> structure can be freed using L<CMS_ContentInfo_free(3)>.
|
|
|
|
CMS_EncryptedData_encrypt() is similar to CMS_EncryptedData_encrypt_ex()
|
|
but uses default values of NULL for the library context I<libctx> and the
|
|
property query I<propq>.
|
|
|
|
=head1 RETURN VALUES
|
|
|
|
If the allocation fails, CMS_EncryptedData_encrypt_ex() and
|
|
CMS_EncryptedData_encrypt() return NULL and set an error code that can be
|
|
obtained by L<ERR_get_error(3)>. Otherwise they return a pointer to the newly
|
|
allocated structure.

=head1 HISTORY
|
|
|
|
The CMS_EncryptedData_encrypt_ex() method was added in OpenSSL 3.0.
