These will be used by Chromium's crypto::ECPrivateKey to work with
EncryptedPrivateKeyInfo structures.
Note this comes with a behavior change: PKCS8_encrypt and PKCS8_decrypt
will no longer preserve PKCS#8 PrivateKeyInfo attributes. However, those
functions are only called by Chromium which does not care. They are also
called by the PEM code, but not in a way which exposes attributes.
The PKCS#12 PFX code is made to use PKCS8_parse_encrypted_private_key
because it's cleaner (no more tossing X509_SIG around) and to ease
decoupling that in the future.
crypto/pkcs8's dependency on the legacy ASN.1 stack is now limited to
pkcs8_x509.c.

With PKCS8_encrypt_pbe and PKCS8_decrypt_pbe gone in
3e8b782c0cc0d9621f622cf80ab1a9bcf442fa17, we can restore the old
arrangement where the password encoding was handled in pkcs12_key_gen.
This simplifies the interface for the follow-up crypto/asn1 split.
Note this change is *not* a no-op for PKCS#12 files which use PBES2.
Before, we would perform the PKCS#12 password encoding for all parts of
PKCS#12 processing. The new behavior is we only perform it for the parts
that go through the PKCS#12 KDF. For such a file, it would only be the
MAC.
I believe the specification supports our new behavior. Although RFC 7292
B.1 says something which implies that the transformation is about
converting passwords to byte strings and would thus be universal,
appendix B itself is prefaced with:
Note that this method for password privacy mode is not recommended
and is deprecated for new usage. The procedures and algorithms
defined in PKCS #5 v2.1 [13] [22] should be used instead.
Specifically, PBES2 should be used as encryption scheme, with PBKDF2
as the key derivation function.
"This method" refers to the key derivation and not the password
formatting, but it does give support to the theory that password
formatting is tied to PKCS#12 key derivation.
(Of course, if one believes PKCS#12's assertion that their inane
encoding (NUL-terminated UTF-16!) is because PKCS#5 failed to talk about
passwords as Unicode strings, one would think that PBES2 (also in
PKCS#5) would have the same issue and thus need PKCS#12 to valiantly
save the day with an encoding...)
This matches OpenSSL's behavior and that of recent versions of NSS. See
https://bugzilla.mozilla.org/show_bug.cgi?id=1268141. I was unable to
figure out what variants, if any, macOS accepts.

Mercifully, PKCS#12 does not actually make ContentInfo and SafeBag
mutually recursive. The top-level object in a PKCS#12 is a SEQUENCE of
data or encrypted data ContentInfos. Their payloads are a SEQUENCE of
SafeBags (aka SafeContents).
SafeBag is a similar structure to ContentInfo but not identical (it has
attributes in it which we ignore) and actually carries the objects.
There is only recursion if the SafeContents bag type is used, which we
do not process.
This means we don't need to manage recursion depth. This also no longer
allows trailing data after the SEQUENCE and removes the comment about
NSS. The test file still passes, so I'm guessing something else was
going on?

Avoid the X509_ALGOR dependency entirely. The public API is still using
the legacy ASN.1 structures for now, but the conversions are lifted to
the API boundary. Once we resolve that and the OID table dependency,
this module will no longer block unshipping crypto/asn1 and friends from
Chromium.
This changes the calling convention around the two kinds of PBE suites
we support. Each PBE suite provides a free-form encrypt_init function to
setup an EVP_CIPHER_CTX and write the AlgorithmIdentifer to a CBB. It
then provides a common decrypt_init function which sets up an
EVP_CIPHER_CTX given a CBS of the parameter. The common encrypt code
determines how to call which encrypt_init function. The common decrypt
code parses the OID out of the AlgorithmIdentifer and then dispatches to
decrypt_init.
Note this means the encryption codepath no longer involves parsing back
out a AlgorithmIdentifier it just serialized. We don't have a good story
to access an already serialized piece of a CBB in progress (reallocs can
invalidate the pointer in a CBS), so it's easier to cut this step out
entirely.
Also note this renames the "PBES1" schemes from PKCS#5 to PKCS#12. This
makes it easier to get at the PKCS#12 key derivation hooks. Although
PKCS#12 claims these are variants of PKCS#5's PBES1, they're not very
related. PKCS#12 swaps out the key derivation and even defines its own
AlgorithmIdentifier parameter structure (identical to the PKCS#5 PBES1
one). The only thing of PBES1 that survives is the CBC mode padding
scheme, which is deep in EVP_CIPHER for us. (Of course, all this musing
on layering is moot because we don't implement non-PKCS#12 PBES1 schemes
anyway.)
This also moves some of the random API features (default iteration
count, default salt generation) out of the PBE suites and into the
common code.

CBS_asn1_ber_to_der currently uses heuristics because implicitly-tagged
constructed strings in BER are ambiguous with implicitly-tagged sequences. It's
not possible to convert BER to DER without knowing the schema.
Fortunately, implicitly tagged strings don't appear often so instead split the
job up: CBS_asn1_ber_to_der fixes indefinite-length elements and constructed
strings it can see. Implicitly-tagged strings it leaves uncoverted, but they
will only nest one level down (because BER kindly allows one to nest
constructed strings arbitrarily!).
CBS_get_asn1_implicit_string then performs the final concatenation at parse
time. This isn't much more complex and lets us parse BER more accurately and
also reject a number of mis-encoded values (e.g. constructed INTEGERs are not a
thing) we'd previously let through. The downside is the post-conversion parsing
code must be aware of this limitation of CBS_asn1_ber_to_der. Fortunately,
there's only one implicitly-tagged string in our PKCS#12 code.
(In the category of things that really really don't matter, but I had spare
cycles and the old BER converter is weird.)
