Also new for App Cloner 1.5.3, a Developer option for commercial license use that allows you use sign clones using your own signing certificate instead of the default unofficial test certificate.
(Remember that the default test certificate may trigger false positive warnings with certain anti-virus apps.)
Supported keystore types are JKS (the default Java keystore type), BKS (BouncyCastle keystore) and the PKCS#12 standard. After loading the keystore from the SD-card, depending on the keystore type you will need to provide the keystore password, the key alias and/or the key password. All of these are stored internally in an encrypted manner and cannot be exported as part of the clone settings.
You may either configure a global certificate under Settings, in which case the certificate will be used for all apps, or per app using the developer option Custom certificate.
Note that if existing clones were signed using a different certificate they need to be uninstalled first.
