Way to encrypt/decrypt files?

Hi there, What would be an easy approach to save a file as an encrypted file, and decrypt it again? The encryption doesn’t need to be strong, just so the user cannot open it. thanks.

Looking to encrypt/decrypt external wavs in my sampler

I would suggest to inherit an InputStream and OutputStream. You can give them to any AudioFormatReader, and you have all freedom, if you get your encrypted data from a File, a MemoryBlock, or anything, even from a GZIPDecompressorInputStream… You need to implement only 5 methods: virtual int64 getTotalLength () virtual bool isExhausted () virtual int read (void *destBuffer, int maxBytesToRead) virtual int64 getPosition () virtual bool setPosition (int64 newPosition) Looks like only t…

Hide samples from users

I invented a very trivial sample obfuscation algorithm for low CPU usage (I was probably not the first to come up with that): Create a noise file that you ship with the samples. This is your public key Mix that noise with your sample with an offset (individual for each sample, makes it a bit harder) when playing back sum the negative noise with the correct offset. Summing is cheap. Caveat: make sure that your wave file accepts values over 1.0f (since you cannot rule that out).

To get you some starting points. It is a tradeoff between more security vs. CPU usage to read the samples.
