CSecretKey
This is an implementation of the hmac, key-hashing authentication code in the C language. The generation of the secret key is included in the final binary.
The secret key is obtained by concatenating 3 String against some pseudo random Strings that make the retrieval of the key a little harder for discrete programmers(hackers).
This can be really useful (I hope so) in mobile Applications (Android & iOS) where the client must be equipped with a secret key to access a private API across the network.
###To customize In hmac_256.c:
- Change aux1, aux2, aux3 contents with yours.
- Change rain and salt to some integers
- Change snow and pepper to some integers
###iOS To show the password generated
make test
./test
Once the password is generated you can hide it by:
make production
At this point, libhmacenc.so is ready to be used in production! Running ./test will not print the password this time.
###Android
To build as JNI code for Android:
leave only source files and Android.mk define or undefined SHOW_PASS to show password in logcat
###Cross-check
To cross-check take the input text string and the password generated and put them in
reverse_test.py. The output must be the same
