 Verify OpenSSL signature:
 ```
-$ wget https://www.openssl.org/source/openssl-1.1.1k.tar.gz.asc
-$ gpg --verify openssl-1.1.1k.tar.gz.asc openssl-1.1.1k.tar.gz

 Continue **ONLY** if the signature is **VALID**.

 Then, retrieve your Android NDK installation path, usually someting like "/home/\<user\>/Android/SDK/ndk/\<NDK version\>". We can now build libgocryptfs: 
 ```
 $ cd DroidFS/app/libgocryptfs
-$ env ANDROID_NDK_HOME="<your ndk path>" OPENSSL_PATH="./openssl-1.1.1k" ./build.sh
+$ env ANDROID_NDK_HOME="<your ndk path>" OPENSSL_PATH="./openssl-1.1.1l" ./build.sh
  ```
 Then, open the DroidFS project with Android Studio. \
 If a device (virtual or physical) is connected, just click on "Run". \
