java - How should I implement a string hashing function for these requirements? -

OK, I need a hashing function to meet the following requirements. I consider part of the same logical structure, But files in different physical areas of the file system have the ability to be linked together.

I need to implement it in Java, it should be consistent with execution sessions and this can return a long time.

I will be getting directory names / strings that should work so that "somefolder1" and "somefolder2" will return a different hash, as "Jjk" and "jjl" .

Any suggestions?

Thank you

For the skirmishes, just see how many large hash outputs have Java's own Hashod () returns a int , so you expect that there is more conflict than this, for example For those who generate 128 and 160 bits respectively,

You should not try to create such a function from scratch, though.

However, I understand a lot Did not come whether there should never be a confrontation in your use or if it is acceptable if they are acceptable or not. To add folders, there may definitely be something more than once, instead of doing it, -to-unique-page He uses Chankrta.
