TextHash is a demo application that calculates that hash-value of a string of text using super-fast ROR+XOR method. Calculation of hash is done on the fly, as soon as you type, making it easier to evaluate the strength of ROR+XOR hash technique.

ROR+XOR hash is as fast as XOR fast, but is immune from the following issues that XOR hash suffers from:

• repeating characters cancel each other hash(abb) = hash(a)
• does not depend on order of characters hash(hello) = hash(loleh)
• for a simple text highest bit is never used hash(<text>).bit(7) == 0

ROR+XOR hash solves these issues simple by rotating the bits by one bit after each operation.

Open TextHash.

Start writing some text. Hash value is calculated as you type.

Notice how the hash value varies with each character.

Moving characters around changes the has value.
