Just because an engine implements algorithm methods, that doesn't mean it also implements the ASN1 method. Therefore, be careful when looking for an ASN1 method among all engines, don't try to use one that doesn't exist. Fixes #6381 Reviewed-by:

XN_FLAG_COMPAT has a unique property, its zero for value. This means it needs special treatment; if it has been set (which can only be determined indirectly) and set alone (*), no other flags should be set. (*) if any other nameopt flag has been set by the user, compatibility mode is blown away. Reviewed-by:

In `aes_wrap_cipher()`, the minimal out buff length is `(inlen - 8)`. Since it calls `CRYPTO_128_unwrap_pad()` underneath, it makes sense to reduce the minimal out length in `CRYPTO_128_unwrap_pad()` to align to its caller. Signed-off-by:

The One&Done attack, which is described in a paper to appear in the USENIX Security'18 conference, uses EM emanations to recover the values of the bits that are obtained using BN_is_bit_set while constructing the value of the window in BN_mod_exp_consttime. The EM signal changes slightly depending on the value of the bit, and since the lookup of a bit is surrounded by highly regular execution (constant-time Montgomery multiplications) the attack is able to isolate the (very brief) part of the signal that changes depending on the bit. Although the change is slight, the attack recovers it successfully >90% of the time on several phones and IoT devices (all with ARM processors with clock rates around 1GHz), so after only one RSA decryption more than 90% of the bits in d_p and d_q are recovered correctly, which enables rapid recovery of the full RSA key using an algorithm (also described in the paper) that modifies the branch-and-prune approach for a situation in which the exponents' bits are recovered with errors, i.e. where we do not know a priori which bits are correctly recovered. The mitigation for the attack is relatively simple - all the bits of the window are obtained at once, along with other bits so that an entire integer's worth of bits are obtained together using masking and shifts, without unnecessarily considering each bit in isolation. This improves performance somewhat (one call to bn_get_bits is faster than several calls to BN_is_bit_set), so the attacker now gets one signal snippet per window (rather than one per bit) in which the signal is affected by all bits in the integer (rather than just the one bit).

Under a mingw shell, the command line path conversion either mangles file: URIs to something useless (file;C:\...) or not at all (which can't be opened by the Windows C RTL unless we're really lucky), so we simply skip testing them in that environment. Fixes #6369 Reviewed-by:

OpenSSL 1.1.0 made the X509_LOOKUP_METHOD structure opaque, so applications that were previously able to define a custom lookup method are not able to be ported. This commit adds getters and setters for each of the current fields of X509_LOOKUP_METHOD, along with getters and setters on several associated opaque types (such as X509_LOOKUP and X509_OBJECT).

In commit 6decf943 , fourteen public symbols were removed from util/libcrypto.num on the master branch and the following symbols renumbered. Unfortunately, the symbols `OCSP_resp_get0_signer` and `X509_get0_authority_key_id` were not adjusted accordingly on the OpenSSL_1_1_0-stable branch. This commit fixes the collision by doing a 'double swap'. Reviewed-by:

In previous versions of OpenSSL, the documentation for PEM_read_* said: The callback B<must> return the number of characters in the passphrase or 0 if an error occurred. But since c82c3462 , 0 is now treated as a non-error return value. Applications that want to indicate an error need to return -1 instead. Reviewed-by:
