Package afis implements Anti-Forensic Information Splitting
The splitter supports secure data destruction crucial for secure on-disk key management. The key idea is to bloat information and therefor improving the chance of destroying a single bit of it. The information is bloated in such a way, that a single missing bit causes the original information become unrecoverable. The theory behind AFsplitter is presented in TKS1.
The interface is simple. It consists of two functions:
Split(data, stripes) Merge(data, stripes)
Split operates on data and returns information splitted data. Merge does just the opposite: uses the information stored in data to recover the original splitted data.

DefaultHash is our default hashing function.
Merge data splitted previously with Split using the default SHA-1 hash.
MergeHash merges data splitted previously with the selected hash function.
Split data using the default SHA-1 hash.
