You can do this programatically by reading the following:

<ul>
<li><a href="http://www.openssl.org/docs/crypto/OPENSSL_VERSION_NUMBER.html" rel="noreferrer"><code>OPENSSL_VERSION_NUMBER(3)</code></a></li>
</ul>

and

<ul>
<li><a href="http://www.openssl.org/docs/crypto/SSLeay_version.html" rel="noreferrer"><code>SSLeay_version(3)</code></a></li>
</ul>

Basically, you will need to use the following functions:

<ul>
<li><code>SSLeay()</code></li>
<li><code>SSLeay_version()</code></li>
</ul>

There is a string inside the library containing the version details called <a href="https://www.openssl.org/docs/crypto/OPENSSL_VERSION_NUMBER.html">SSLEAY_VERSION</a> - it looks like:

<ul>
<li><code>OpenSSL 0.9.5a 1 Apr 2000</code></li>
<li><code>OpenSSL 1.0.1e-fips 11 Feb 2013</code></li>
</ul>

You can find this from the binary library using strings and grep:

<pre><code>strings libcrypto.so | grep "^OpenSSL \S\+ [0-9]\+ \S\+ [0-9]\+"
</code></pre>

Well the filtering may may not always work. You could do

blocks|key|384366|text|我需要一个https://stackoverflow.com/a/26635393/597742的变体，它可以在没有安装strings的系统上工作。这是非常不同的，似乎值得张贴作为它自己的答案：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|384367|grep+--text+-o+'OpenSSL+[[:digit:]][%5E+]*'+/file/to/check|code-block|syntax|javascript|384368|--text允许直接检查二进制文件，-o只通过打印匹配的文本来说明缺少行分隔符的原因。|384369|对于这个答案和基于strings的答案，有一点值得注意:除了检查libssl或libcrypto的OpenSSL版本之外，它们还可以在静态链接的二进制文件中检查OpenSSL版本。|384370|entityMap|0|LINK|mutability|MUTABLE|url|https://stackoverflow.com/a/26635393/597742^0|1O|7|5|17|0|0|0|0|6|I|2|0|9|7|W|6|13|9|0^^$0|@$1|2|3|4|5|6|7|W|8|@$9|X|A|Y|B|C]]|D|@$9|Z|A|10|1|11]]|E|$]]|$1|F|3|G|5|H|7|12|8|@]|D|@]|E|$I|J]]|$1|K|3|L|5|6|7|13|8|@$9|14|A|15|B|C]|$9|16|A|17|B|C]]|D|@]|E|$]]|$1|M|3|N|5|6|7|18|8|@$9|19|A|1A|B|C]|$9|1B|A|1C|B|C]|$9|1D|A|1E|B|C]]|D|@]|E|$]]|$1|O|3|-4|5|6|7|1F|8|@]|D|@]|E|$]]]|P|$Q|$5|R|S|T|E|$U|V]]]]

I needed a variant of <a href="https://stackoverflow.com/a/26635393/597742">https://stackoverflow.com/a/26635393/597742</a> that would work on systems without <code>strings</code> installed. It's sufficiently different that it seemed worthwhile to post as its own answer:
<pre><code>grep --text -o 'OpenSSL [[:digit:]][^ ]*' /file/to/check
</code></pre>
<code>--text</code> allows the binary to be checked directly, <code>-o</code> accounts for the lack of line separators by only printing the matching text.
A point worth noting for both this answer and the <code>strings</code> based answer: in addition to being useful to check the OpenSSL version of <code>libssl</code> or <code>libcrypto</code>, they also work to check OpenSSL versions in statically linked binaries.

I have a pre-built OpenSSL library (libssl.a and libcrypto.a) which are being used for my C++ application. I don't know the version of the OpenSSL library.

Is there any way to get the version number from these pre-built libraries?

我有一个预构建的OpenSSL库(libssl.a和libcryp.a)，用于我的C++应用程序。我不知道OpenSSL库的版本。有没有办法从这些预先构建的库中获取版本号？
