encryption - Encoding/Decoding client (android) and server (PHP) side -

i have project in have send info android app mysql database via php webservices. of course of study want info encrypted.

we decided utilize rsa 1024 encrypt , decrypt, i've found troubles utilize public&private keys agreed use.

this code encrypting

privatekey = 'abcdefghijk'; byte[] encodedbytes = null; seek { cipher c = cipher.getinstance("rsa"); c.init(cipher.encrypt_mode, privatekey); encodedbytes = c.dofinal(thetesttext.getbytes()); } grab (exception e) { log.e(tag, "rsa encryption error"); }

and 1 decrypting

publickey = 'secretpubkey'; byte[] decodedbytes = null; seek { cipher c = cipher.getinstance("rsa"); c.init(cipher.decrypt_mode, publickey); decodedbytes = c.dofinal(encodedbytes); } grab (exception e) { log.e(tag, "rsa decryption error"); }

publickey , privatekey aren't string type, because init function asks me key type, seems can't whatever value want key type.

can help me?? give thanks you!

python - How to add an model instance to a django queryset? - it seems django queryset behaves somehow python list. but doesn't back upwards list's .append() method know. what want like: from my_django_app.models import mymodel queryset = mymodel.objects.none() queryset.append(mymodel.objects.first()) ## no list's .append() method! is there way add together model instance existing queryset? no. queryset representation of query - hence name - not arbitrary collection of instances. if need actual queryset rather list, seek accumulating ids of objects need , getting objects via __in query: list_of_ids = [] list_of_ids.append(my_id) ... queryset = mymodel.objects.filter(id__in=list_of_ids) this isn't efficient, though. python django
