I've left EVP_set_buggy_rsa_parser as a no-op stub for now, but it

28d6979b7e Print errors better in FileTestGTest.
Rather than clear them, even on failure, detect if an individual test
failed and dump the error queue there. We already do this at the GTest
level in ErrorTestEventListener, but that is too coarse-grained for the
file tests.

b529253bea Implement scrypt from RFC 7914.
This imports upstream's scrypt implementation, though it's been heavily
revised. I lost track of words vs. blocks vs. bigger blocks too many
times in the original code and introduced a typedef for the fixed-width
Salsa20 blocks. The downside is going from bytes to blocks is a bit
trickier, so I took advantage of our little-endian assumption.

This also adds an missing check for N < 2^32. Upstream's code is making
this assumption in Integerify. I'll send that change back upstream. I've
also removed the weird edge case where a NULL out_key parameter means to
validate N/r/p against max_mem and nothing else. That's just in there to
get a different error code out of their PKCS#12 code.

Performance-wise, the cleanup appears to be the same (up to what little
precision I was able to get here), but an optimization to use bitwise
AND rather than modulus makes us measurably faster. Though scrypt isn't
a fast operation to begin with, so hopefully it isn't anyone's
bottleneck.

This CL does not route scrypt up to the PKCS#12 code, though we could
write our own version of that if we need to later.

19670949ca Align EVP_PKEY Ed25519 API with upstream.
Rather than adding a new mode to EVP_PKEY_CTX, upstream chose to tie
single-shot signing to EVP_MD_CTX, adding functions which combine
EVP_Digest*Update and EVP_Digest*Final. This adds a weird vestigial
EVP_MD_CTX and makes the signing digest parameter non-uniform, slightly
complicating things. But it means APIs like X509_sign_ctx can work
without modification.

Align with upstream's APIs. This required a bit of fiddling around
evp_test.cc. For consistency and to avoid baking details of parameter
input order, I made it eagerly read all inputs before calling
SetupContext. Otherwise which attributes are present depend a lot on the
shape of the API we use---notably the NO_DEFAULT_DIGEST tests for RSA
switch to failing before consuming an input, which is odd.

(This only matters because we have some tests which expect the operation
to abort the operation early with parameter errors and match against
Error. Those probably should not use FileTest to begin with, but I'll
tease that apart a later time.)

Upstream also named NID_Ed25519 as NID_ED25519, even though the
algorithm is normally stylized as "Ed25519". Switch it to match.

16c3f06eb0 Convert evp_test to GTest.
This is a fairly shallow conversion because of the somewhat screwy Error
lines in the test which may target random functions like
EVP_PKEY_CTX_set_signature_md. We probably should revise this, perhaps
moving those to normal tests and leaving error codes to the core
operation itself.

This allows us to implement RSA-PSS in the FIPS module without pulling

which is unfortunate.

05821b0ee3 Consistently check length in RSA_add_pkcs1_prefix.
We check the length for MD5+SHA1 but not the normal cases. Instead,
EVP_PKEY_sign externally checks the length (largely because the silly
RSA-PSS padding function forces it). We especially should be checking
the length for these because otherwise the prefix built into the ASN.1
prefix is wrong.

The primary motivation is to avoid putting EVP_PKEY inside the FIPS
module. This means all logic for supported algorithms should live in
crypto/rsa.

This requires fixing up the verify_recover logic and some tests,
including bcm.c's KAT bits.

(evp_tests.txt is now this odd mixture of EVP-level and RSA-level error
codes. A follow-up change will add new APIs for RSA-PSS which will allow
p_rsa.c to be trimmed down and make things consistent.)

This was a mess. HMAC_CTX_copy_ex would avoid having to cleanup and init
the HMAC_CTX repeatedly, but even that is unnecessary. hctx_tpl was just
to reuse the key. Instead, HMAC_CTX already can be reset with the same
key. (Alas, with a slightly odd API, but so it goes.) Do that, and use
goto err to cleanup the error-handling.

Thanks to upstream's b98530d6e09f4cb34c791b8840e936c1fc1467cf for
drawing attention to this. (Though we've diverged significantly from

5e2d0c929c Add some more RSA-PSS verification tests.
Playing around with the code, we seem to have sufficient positive test
vectors for the logic around the high bits, but not negative test
vectors. Add some. Also add a negative test vector for the trailing
byte.

(For future reference, use openssl rsautl -raw for raw RSA operations
and openssl pkeyutil for EVP_PKEY_sign.)

fd67f61bb4 Fix bounds check in RSA_verify_PKCS1_PSS_mgf1 when sLen is -2.
(Imported from upstream's 04cf39207f94abf89b3964c7710f22f829a1a78f.)

The other half of the change was fixed earlier, but this logic was still
off. This code is kind of a mess and needs a rewrite, but import the
change to get it correct and sufficiently tested first.

(If we could take the sLen = -2 case away altogether, that would be
great...)

591f251bf3 Remove direct calls to BN_mod_exp.
Within the library, we never need to exponentiate modulo an even number.
In fact, all the remaining BN_mod_exp calls are modulo an odd prime.
This extends 617804adc5 to the rest of the
library.

17cf2cb1d2 Work around language and compiler bug in memcpy, etc.
Most C standard library functions are undefined if passed NULL, even
when the corresponding length is zero. This gives them (and, in turn,
all functions which call them) surprising behavior on empty arrays.
Some compilers will miscompile code due to this rule. See also
https://www.imperialviolet.org/2016/06/26/nonnull.html

Add OPENSSL_memcpy, etc., wrappers which avoid this problem.

BUG=23

4f57074bfa Check input length to pkey_rsa_verify and add initial tests.
This is imported from upstream's
71bbc79b7d3b1195a7a7dd5f547d52ddce32d6f0 and test vectors taken
initially from 2d7bbd6c9fb6865e0df480602c3612652189e182 (with a handful
more added).

The tests are a little odd because OpenSSL supports this "salt length
recovery" mode and they go through that codepath for all verifications.

This was done just by grepping for 'size_t i;' and 'size_t j;'. I left

There's some instances in gcm.c that are non-trivial and pulled into a
separate CL for ease of review.

f0e935d7ce Fold stack-allocated types into headers.
Now that we have the extern "C++" trick, we can just embed them in the
normal headers. Move the EVP_CIPHER_CTX deleter to cipher.h and, in
doing so, take away a little bit of boilerplate in defining deleters.
