Everytime a new versions of browsers show up I hear about new stuff being added, like say webGL and other technologies that no one really knows if they catch up. Show But I wonder if someone ever thought about such basic stuff in JS like hashing functions (MD5,SHA1 and the like). By newest browsers I mean today's development versions too like Opera 12, Chrome 17 or Firefox 10. Looking now for solution I found this comment on another thread here: https://stackoverflow.com/questions/7204097/short-hashing-function-for-javascript (Do you know that javascript objects already are hashtables ?). So what are these 'hashtables' ? Does it mean that I can make any string into a hash, but not an established one like md5 or sha1 but some JS build in specific ? basically what I need to do is:

3 For anybody still looking for this information. There is a WebCrypto API which appears to have been finalised at the beginning of 2017. To use it in a browser, you can find it at answered Jul 9, 2017 at 16:14

Do not use this in the context where cryptographic security is needed. This may be useful when you need a simple reversible encryption with "builtin" support. When I need simple client side hashing without external libraries I use the browsers' built in window.btoa() creates a base-64 encoded ASCII string from a "string" of binary data.
The window.atob() function decodes a string of data which has been encoded using base-64 encoding.
http://caniuse.com/#search=btoa and http://caniuse.com/#search=atob shows it is hugely supported by the modern browsers Example taken from https://developer.mozilla.org/en-US/docs/Web/API/window.btoa answered Aug 21, 2014 at 9:56

Browse other questions tagged javascript hash or ask your own question.Does JavaScript have a built in hash function?JavaScript hash() function | Explained. In computer programming, the data structure is used to store, organise, and utilise the data. Javascript hash() function converts the input strings into fixed-sized data (numbers) and returns the hash value.
What JavaScript library provides a hashing function?jshashes is lightweight library implementing the most extended cryptographic hash function algorithms in pure JavaScript (ES5 compliant).
Is JavaScript object HashTable?A JavaScript Object is an example of a Hash Table because data is represented a key/value pairs. A hashing function can be used to map the key to an index by taking an input of any size and returning a hash code identifier of a fixed size.
What is hashing in JS?Hashing is a technique to convert a range of key values into a range of indexes of an array. We're going to use modulo operator to get a range of key values. Consider an example of a hash table of size 20, and the following items are to be stored. Item is in the (key, value) format.
