Back to the standard "app" module.

This return to "app" instead of "bitmask_android" is due to this reading: https://developer.android.com/sdk/installing/studio-build.html#projectStructure
I'll have to tweak the final apk name in build.gradle.

+# Sample script to perform OCSP queries with OpenSSL
+# given a certificate serial number.
+
+# If you run your own CA, you can set up a very simple
+# OCSP server using the -port option to "openssl ocsp".
+
+# Full documentation and examples:
+# http://www.openssl.org/docs/apps/ocsp.html
+
+
+# Edit the following values to suit your needs
+
+# OCSP responder URL (mandatory)
+# YOU MUST UNCOMMENT ONE OF THESE AND SET IT TO A VALID SERVER
+#ocsp_url="http://ocsp.example.com/"
+#ocsp_url="https://ocsp.secure.example.com/"
+
+# Path to issuer certificate (mandatory)
+# YOU MUST SET THIS TO THE PATH TO THE CA CERTIFICATE
+issuer="/path/to/CAcert.crt"
+
+# use a nonce in the query, set to "-no_nonce" to not use it
+nonce="-nonce"
+
+# Verify the response
+# YOU MUST SET THIS TO THE PATH TO THE RESPONSE VERIFICATION CERT
+verify="/path/to/CAcert.crt"
+
+# Depth in the certificate chain where the cert to verify is.
+# Set to -1 to run the verification at every level (NOTE that
+# in that case you need a more complex script as the various
+# parameters for the query will likely be different at each level)
+# "0" is the usual value here, where the client certificate is
+check_depth=0
+
+cur_depth=$1     # this is the *CURRENT* depth
+common_name=$2   # CN in case you need it
+
+# minimal sanity checks
