is there any builtin javascript string hash function in newest browsers?

Question

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.

But I w

Answer 1

Paul Johnston has implemented the following algorithms in javascript

MD5, RIPEMD-160, SHA-1, SHA-256 and sha-512

You can find the source code and some examples here: http://pajhome.org.uk/crypt/md5/

I hope this is what you were looking for.

Answer 2

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 window.crypto.subtle which contains methods for encryption, digests etc. Documentation on the available functions here.

Answer 3

When I need simple client side hashing without external libraries I use the browsers' built in atob() and btoa() functions.

window.btoa() creates a base-64 encoded ASCII string from a "string" of binary data.

function utf8_to_b64( str ) {
    return window.btoa(encodeURIComponent( escape( str )));
}

The window.atob() function decodes a string of data which has been encoded using base-64 encoding.

function b64_to_utf8( str ) {
    return unescape(decodeURIComponent(window.atob( str )));
}

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

Note: Above solution has no external library dependency. As mentioned above, use this only for simple encryption. If you are looking for a secure cryptographic solution do not use this.
