A simple yet often useful scripting task is getting the hash value for a string. Since I recently wrote this very short function for my colleague Laurent Banon (blog) allow me to share it with you.function Hash($textToHash){$hasher = new-object System.Security.Cryptography.SHA256Managed$to...

Some hash function assume a padded input buffer which can be accessed past its length up to the word size. This allows for faster loop processing, as no 2nd loop or switch table for the rest is needed, but it requires a cooperative calling enviroment and is as such considered cheating. Si...

For example, a hash function for a string might take the ASCII codes of each character in the string and add them together to generate a hash code. The string "picnic" would have a hash code that is different from the hash code for the string "basket"; therefore, the strings "picnic"...
