Good, so I eventually managed to solve the problem.
I downloaded openssl for windows from here
Keytool can be found at E:\Program Files\Java\jdk1.7.0_17\bin
Then, using keytool and openssl, I managed to create key.pk8 and certificate.pem in the keystore record
openssl pkcs8 -inform DER -nocrypt -in key.pk8 -out key.pem openssl pkcs12 -export -in certificate.pem -inkey key.pem -out platform.p12 -password pass:android -name mykey keytool -importkeystore -deststorepass password -destkeystore .keystore -srckeystore platform.p12 -srcstoretype PKCS12 -srcstorepass android keytool -list -v -keystore .keystore
The final step is to simply verify that the key has been added to the keystore.
