                            <customfieldvalue>&lt;p&gt;&lt;b&gt;Summary of necessary driver changes&lt;/b&gt;&lt;/p&gt;

&lt;p&gt;Package the crypto-enabled libmongocrypt on platforms where it is safe to do so: Mac and Windows. For Linux, continue to package the crypto-disabled (nocrypto) builds due to the issues with OpenSSL versioning (see &lt;a href=&quot;https://jira.mongodb.org/browse/MONGOCRYPT-112&quot; title=&quot;Create pluggable encryption layer&quot; class=&quot;issue-link&quot; data-issue-key=&quot;MONGOCRYPT-112&quot;&gt;&lt;del&gt;MONGOCRYPT-112&lt;/del&gt;&lt;/a&gt;).&lt;/p&gt;

&lt;p&gt;Check if the loaded libmongocrypt supports native crypto by calling &lt;tt&gt;mongocrypt_is_crypto_available&lt;/tt&gt;. Only register crypto callbacks if it returns false.&lt;/p&gt;

&lt;p&gt;Document that on Linux, high-performance use cases should install libmongocrypt on the system. If possible, ensure this install takes precedence over the packaged crypto-disabled libmongocrypt.&lt;/p&gt;

&lt;p&gt;&lt;b&gt;Context for other referenced/linked tickets&lt;/b&gt;&lt;/p&gt;

&lt;p&gt;&lt;tt&gt;mongocrypt_is_crypto_available&lt;/tt&gt; is added in &lt;a href=&quot;https://jira.mongodb.org/browse/MONGOCRYPT-616&quot; title=&quot;Add API to determine if built with native crypto&quot; class=&quot;issue-link&quot; data-issue-key=&quot;MONGOCRYPT-616&quot;&gt;&lt;del&gt;MONGOCRYPT-616&lt;/del&gt;&lt;/a&gt;. Until it is released, libmongocrypt binaries can be downloaded from the &lt;a href=&quot;https://spruce.mongodb.com/task/libmongocrypt_publish_upload_all_9bd7e00acc3c87d804f7d1b842acb376f0a01fe4_24_01_25_18_57_43&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;upload-all task for the commit&lt;/a&gt;.&lt;/p&gt;

&lt;p&gt;I expect this work only applies to drivers that implement the crypto hooks (i.e. calling &lt;tt&gt;mongocrypt_setopt_crypto_hooks&lt;/tt&gt; and friends). From &lt;a href=&quot;https://docs.google.com/spreadsheets/d/1NKtmYEr_Zrf_eDATpfCBfWyLH8GC1vj075aSCLqrca0/edit#gid=0&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;this survey&lt;/a&gt;, this appears to be: C#, Java, Node.js, Python, Ruby.&lt;/p&gt;</customfieldvalue>
