我已经使用下面给出的脚本编译了Openssl 3.1.0和FIPS。安装成功并且工作正常。但是如果启用FIPS，则无法进行任何出站连接，得到EE certificate too week error。

wget https://www.openssl.org/source/openssl-3.1.0.tar.gz \
    && tar zxvf openssl-3.1.0.tar.gz \
    && cd openssl-3.1.0 \
    && CFLAGS=-fPIC ./config enable-fips --prefix=/usr/local/openssl --openssldir=/usr/local/openssl \
    && make \
    && make test \
    && make install \
    && bash -c "echo '/usr/local/openssl/lib64' >> /etc/ld.so.conf" \
    && ldconfig

openssl version
OpenSSL 3.1.0 14 Mar 2023 (Library: OpenSSL 3.1.0 14 Mar 2023)

通过在openssl配置中包含fipsmodule.cnf文件和添加fips提供程序来启用FIPS。

.include /usr/local/openssl/fipsmodule.cnf

..
..
..

# List of providers to load
[provider_sect]
default = default_sect

# The fips section name should match the section name inside the
# included fipsmodule.cnf.
fips = fips_sect

已通过为文件生成MD5散列来验证启用了FIPS，但如预期出现错误。

openssl md5 <file_path>

但所有的对外连接都失败了，

任何帮助解决这个问题，谢谢。
