 Verify OpenSSL signature:

 Retrieve your Android NDK installation path, usually something like "/home/\<user\>/Android/SDK/ndk/\<NDK version\>". Now you can build libgocryptfs:
 ```
 $ cd DroidFS/app/libgocryptfs
-$ env ANDROID_NDK_HOME="<your ndk path>" OPENSSL_PATH="./openssl-1.1.1m" ./build.sh
+$ env ANDROID_NDK_HOME="<your ndk path>" OPENSSL_PATH="./openssl-1.1.1n" ./build.sh
  ```
 Then FFmpeg:
