Daniel Van Geest d0899abb1b Implement KEMRecipientInfo (RFC9629) in CMS
Also add support for ML-KEM in CMS (draft-ietf-lamps-cms-kyber).

Add the -recip_kdf and -recip_ukm parameters to `openssl cms -encrypt`
to allow the user to specify the KDF algorithm and optional user
keying material for each recipient.

A provider may indicate which RecipientInfo type is supported
for a key, otherwise CMS will try to figure it out itself. A
provider may also indicate which KDF to use in KEMRecipientInfo
if the user hasn't specified one.

Richard Levitte e077455e9e Stop raising ERR_R_MALLOC_FAILURE in most places
Since OPENSSL_malloc() and friends report ERR_R_MALLOC_FAILURE, and
at least handle the file name and line number they are called from,
there's no need to report ERR_R_MALLOC_FAILURE where they are called
directly, or when SSLfatal() and RLAYERfatal() is used, the reason
`ERR_R_MALLOC_FAILURE` is changed to `ERR_R_CRYPTO_LIB`.

There were a number of places where `ERR_R_MALLOC_FAILURE` was reported
even though it was a function from a different sub-system that was
called.  Those places are changed to report ERR_R_{lib}_LIB, where
{lib} is the name of that sub-system.
Some of them are tricky to get right, as we have a lot of functions
that belong in the ASN1 sub-system, and all the `sk_` calls or from
the CRYPTO sub-system.

Some extra adaptation was necessary where there were custom OPENSSL_malloc()
wrappers, and some bugs are fixed alongside these changes.

Rich Salz f6c95e46c0 Add "origin" field to EVP_CIPHER, EVP_MD
Add a "where did this EVP_{CIPHER,MD} come from" flag: global, via fetch,
or via EVP_{CIPHER,MD}_meth_new.  Update EVP_{CIPHER,MD}_free to handle all
three origins. The flag is deliberately right before some function pointers,
so that compile-time failures (int/pointer) will occur, as opposed to
taking a bit in the existing "flags" field.  The "global variable" flag
is non-zero, so the default case of using OPENSSL_zalloc (for provider
ciphers), will do the right thing. Ref-counting is a no-op for
Make up_ref no-op for global MD and CIPHER objects

Deprecate EVP_MD_CTX_md().  Added EVP_MD_CTX_get0_md() (same semantics as
the deprecated function) and EVP_MD_CTX_get1_md().  Likewise, deprecate
EVP_CIPHER_CTX_cipher() in favor of EVP_CIPHER_CTX_get0_cipher(), and add
EVP_CIPHER_CTX_get1_CIPHER().

Refactor EVP_MD_free() and EVP_MD_meth_free() to call new common
evp_md_free_int() function.
Refactor EVP_CIPHER_free() and EVP_CIPHER_meth_free() to call new common
evp_cipher_free_int() function.

Also change some flags tests to explicit test == or != zero. E.g.,
        if (flags & x) --> if ((flags & x) != 0)
        if (!(flags & x)) --> if ((flags & x) == 0)
Only done for those lines where "get0_cipher" calls were made.

Dr. Matthias St. Pierre 25f2138b0a Reorganize private crypto header files
Currently, there are two different directories which contain internal
header files of libcrypto which are meant to be shared internally:

While header files in 'include/internal' are intended to be shared
between libcrypto and libssl, the files in 'crypto/include/internal'
are intended to be shared inside libcrypto only.

To make things complicated, the include search path is set up in such
a way that the directive #include "internal/file.h" could refer to
a file in either of these two directoroes. This makes it necessary
in some cases to add a '_int.h' suffix to some files to resolve this
ambiguity:

  #include "internal/file.h"      # located in 'include/internal'
  #include "internal/file_int.h"  # located in 'crypto/include/internal'

This commit moves the private crypto headers from

  'crypto/include/internal'  to  'include/crypto'

As a result, the include directives become unambiguous

  #include "internal/file.h"       # located in 'include/internal'
  #include "crypto/file.h"         # located in 'include/crypto'

hence the superfluous '_int.h' suffixes can be stripped.

The files 'store_int.h' and 'store.h' need to be treated specially;
they are joined into a single file.

Bernd Edlinger 5840ed0cd1 Fix a padding oracle in PKCS7_dataDecode and CMS_decrypt_set1_pkey
An attack is simple, if the first CMS_recipientInfo is valid but the
second CMS_recipientInfo is chosen ciphertext. If the second
recipientInfo decodes to PKCS #1 v1.5 form plaintext, the correct
encryption key will be replaced by garbage, and the message cannot be
decoded, but if the RSA decryption fails, the correct encryption key is
used and the recipient will not notice the attack.

As a work around for this potential attack the length of the decrypted
key must be equal to the cipher default key length, in case the
certifiate is not given and all recipientInfo are tried out.

The old behaviour can be re-enabled in the CMS code by setting the
CMS_DEBUG_DECRYPT flag.
