在WAMP/Apache的openssl.exe中找不到序号372

Question

我使用的PHP框架需要OpenSSL用于各种功能,但在执行与OpenSSL相关的任何内容时,我收到以下错误:"无法在DLL文件C中找到序号372:\ wamp64\bin\apache\apache2.4.17\bin\openssl.exe".

我根本不知道如何纠正这个问题,我已经到处寻找了.我很感激帮助,因为我不知道如何解决这个问题.

要解决这个问题,需要做两件事:

1)确保您的Apache bin目录中没有libeay32.dll和ssleay32.dll的符号链接(例如,我的是:C:\ wamp64\bin\apache\apache2.4.23\bin)

如果您确实有符号链接(即文件大小为0字节),则需要从Apache Lounge下载dll.例如,我从https://www.apachelounge.com/download/上托管的64位版本的Apache 2.4.23中获取了两个.dll文件.

2)恢复实际的.dll文件后,需要确保WampServer不会覆盖它们.WampServer 3有一个配置脚本,每次启动时都会运行.在该脚本中,它将使用符号链接覆盖这些.dll.您必须禁用该功能.为此,请在以下位置注释掉对这两个文件的引用:C:\ wamp64\scripts\config.inc.php(我的位于第133和139行).

这应该允许您在Apache中启用mod_ssl模块.在启用mod_ssl的情况下正确启动Apache后,您还需要取消注释"Include conf/extra/httpd-ssl.conf".(但是,您可能需要删除其中的大部分内容并重新开始,因为它包含大量硬编码路径和错误)

...“在 DLL 文件 C:\wamp64\bin\apache\apache2.4.17\bin\openssl.exe 中找不到序号 372”

我推测它PEM_SealInit或SSL_CONF_cmd_argv来自 OpenSSL 1.0.2；或 ASN1_i2d_fp或SSL_SESSION_set1_id_context来自 OpenSSL 1.1.0。

# OpenSSL 1.1.0
$ find $PWD -type f -iname '*.num' -exec grep " 372" {} \;
ASN1_i2d_fp                             372   1_1_0   EXIST::FUNCTION:STDIO
SSL_SESSION_set1_id_context             372   1_1_0   EXIST::FUNCTION:
...

# OpenSSL 1.0.2
$ find $PWD -type f -iname '*.num' -exec grep " 372" {} \;
PEM_SealInit                            372   EXIST::FUNCTION:RSA
SSL_CONF_cmd_argv                       372   EXIST::FUNCTION:
...

您需要使用Dependency Walkerdumpbin或Dependency Walker 来验证它。另请参阅如何从序数中找到导出的函数名称（按序数导出）？在堆栈溢出上。

序数是使用创建的<openssl src>\util\mkdef.pl。您可以从 OpenSSL 的 GitHub 上查看源代码。这里是 1.0.2，这里是 1.1.0。

以下是该文件的主要注释：

#!/usr/local/bin/perl -w
#
# generate a .def file
#
# It does this by parsing the header files and looking for the
# prototyped functions: it then prunes the output.
#
# Intermediary files are created, call libcrypto.num and libssl.num,
# The format of these files is:
#
#   routine-name    nnnn    vers    info
#
# The "nnnn" and "vers" fields are the numeric id and version for the symbol
# respectively. The "info" part is actually a colon-separated string of fields
# with the following meaning:
#
#   existence:platform:kind:algorithms
#
# - "existence" can be "EXIST" or "NOEXIST" depending on if the symbol is
#   found somewhere in the source, 
# - "platforms" is empty if it exists on all platforms, otherwise it contains
#   comma-separated list of the platform, just as they are if the symbol exists
#   for those platforms, or prepended with a "!" if not.  This helps resolve
#   symbol name variants for platforms where the names are too long for the
#   compiler or linker, or if the systems is case insensitive and there is a
#   clash, or the symbol is implemented differently (see
#   EXPORT_VAR_AS_FUNCTION).  This script assumes renaming of symbols is found
#   in the file crypto/symhacks.h.
#   The semantics for the platforms is that every item is checked against the
#   environment.  For the negative items ("!FOO"), if any of them is false
#   (i.e. "FOO" is true) in the environment, the corresponding symbol can't be
#   used.  For the positive itms, if all of them are false in the environment,
#   the corresponding symbol can't be used.  Any combination of positive and
#   negative items are possible, and of course leave room for some redundancy.
# - "kind" is "FUNCTION" or "VARIABLE".  The meaning of that is obvious.
# - "algorithms" is a comma-separated list of algorithm names.  This helps
#   exclude symbols that are part of an algorithm that some user wants to
#   exclude.
