This change causes FIPS mode to use RDRAND in preference to the kernel's
entropy pool. This prevents issues where the ioctl that we have to do
when getrandom isn't supported transiently reports that the pool is
“empty” and causes us to block.

Rather than comparing against both endpoints, subtract the minimum and
rely on unsigned wraparound to do both comparisons at once. This seems
to be slightly faster.
In addition, constant_time_lt_8 becomes much simpler if it can assume
that |a| and |b| have the same MSB. But we can arrange that by casting
up to |crypto_word_t| (which is otherwise happening anyway).

With the constant-time base64 decode, base64_ascii_to_bin is a bit more
expensive. This check is redundant with the one in base64_decode_quad,
though it does mean syntax error reporting will be slightly deferred by
four bytes.

FIPS 186-4 wants d = e^-1 (mod lcm(p-1, q-1)), not (p-1)*(q-1).
Note this means the size of d might reveal information about p-1 and
q-1. However, we do operations with Chinese Remainder Theorem, so we
only use d (mod p-1) and d (mod q-1) as exponents. Using a minimal
totient does not affect those two values.
This removes RSA_recover_crt_params. Using a minimal d breaks (or rather
reveals an existing bug in) the function.
While I'm here, rename those ridiculous variable names.

Nothing is using them. For encrypt, there's generally no need to swap
out public key operations. keygen seems especially pointless as one
could just as easily call the other function directly.
The one behavior change is RSA_encrypt now gracefully detects if called
on an empty RSA, to match the other un-RSA_METHOD-ed functions which had
similar treatments. (Conscrypt was filling in the encrypt function
purely to provide a non-crashing no-op function. They leave the public
bits blank and pass their custom keys through sufficiently many layers
of Java crypto goo that it's not obvious whether this is reachable.)
We still can't take the function pointers out, but once
96bbe03dfd
trickles back into everything, we can finally prune RSA_METHOD.
Bump BORINGSSL_API_VERSION as a convenience so I can land the
corresponding removal in Conscrypt immediately.

which is unfortunate.

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.)
