7f09a8773b Include "constant_time_locl.h" rather than "../constant_time_locl.h".
The different -I compiler parameters will take care of the rest...

1cfd255c91 Add additional DigestInfo checks.
Reencode DigestInto in DER and check against the original: this
will reject any improperly encoded DigestInfo structures.

Note: this is a precautionary measure, there is no known attack
which can exploit this.

Thanks to Brian Smith for reporting this issue.

294d1e36c2 RT3066: rewrite RSA padding checks to be slightly more constant time.
Also tweak s3_cbc.c to use new constant-time methods.
Also fix memory leaks from internal errors in RSA_padding_check_PKCS1_OAEP_mgf1

This patch is based on the original RT submission by Adam Langley <agl@chromium.org>,
as well as code from BoringSSL and OpenSSL.

44e0c2bae4 RT2626: Change default_bits from 1K to 2K
This is a more comprehensive fix.  It changes all
keygen apps to use 2K keys. It also changes the
default to use SHA256 not SHA1.  This is from
Kurt's upstream Debian changes.

2afb29b480 RT992: RSA_check_key should have a callback arg
The original RT request included a patch.  By the time
we got around to doing it, however, the callback scheme
had changed. So I wrote a new function RSA_check_key_ex()
that uses the BN_GENCB callback.  But thanks very much
to Vinet Sharma <vineet.sharma@gmail.com> for the
initial implementation.

0574cadf85 CMS RSA-OAEP and RSA-PSS support.
Extend RSA ASN1 method to support CMS PSS signatures for both sign
and verify.

For signing the EVP_PKEY_CTX parameters are read and the appropriate
CMS structures set up.

For verification the CMS structures are analysed and the corresponding
parameters in the EVP_PKEY_CTX set.

Also add RSA-OAEP support.

For encrypt the EVP_PKEY_CTX parameters are used.

For decrypt the CMS structure is uses to set the appropriate EVP_PKEY_CTX
parameters.

7c770d572a Add and use a constant-time memcmp.
This change adds CRYPTO_memcmp, which compares two vectors of bytes in
an amount of time that's independent of their contents. It also changes
several MAC compares in the code to use this over the standard memcmp,
which may leak information about the size of a matching prefix.

5863163732 Additional compatibility fix for MDC2 signature format.
Update RSA EVP_PKEY_METHOD to use the OCTET STRING form of MDC2 signature:
this will make all versions of MDC2 signature equivalent.

Dr. Stephen Henson
83cb7c4635 An incompatibility has always existed between the format used for RSA
signatures and MDC2 using EVP or RSA_sign. This has become more apparent
when the dgst utility in OpenSSL 1.0.0 and later switched to using the
EVP_DigestSign functions which call RSA_sign.

This means that the signature format OpenSSL 1.0.0 and later used with
dgst -sign and MDC2 is incompatible with previous versions.

Add detection in RSA_verify so either format works.

Note: MDC2 is disabled by default in OpenSSL and very rarely used in practice.
