JavaScript MD5

It can be used for generating passwords, protecting strings or self-decrypting pages.

This allows web sites to perform simple cryptography on clients.

It takes a string as input, and produces a 128-bit number, the hash.

The same string always produces the same hash, but given a hash, it is not generally possible to determine the original string.

Secure hash algorithms are useful for protecting passwords and ensuring data integrity.

Features:

• Algorithms:
• SHA-1
• SHA-256
• SHA-512
• MD5
• RIPEMD-160
• HMAC

What is new in this release:

• Changes:
• More algorithms - RIPEMD-160, SHA-256 and SHA-512 are now supported, based on contributed code. Support for MD4 has been dropped.
• Compressed versions of the scripts are available, processed by YUI Compressor. sha1-min.js is less than 3KB.
• Improved Unicode support. By default, the input string is now encoded as utf-8, before being hashed, which is what most people want. It is still possible to use utf-16, but the chrsz configuration variable is gone.
• Arbitrary output encoding. You can specify a string of characters to use for output encoding; the string length does not need to be a power of two. This is helpful for password makers, which want to use as much unpredictability as possible, in a short password.
• Bug fixes:
• The scripts now work correctly if immediate code is not executed, so they support some unusual platforms, including GreaseMonkey.
• rstr2binl now preinitialises the array with zeros, to work around bugs in some browsers.
• md5_vm_test now works if hex_case is set to 1

Requirements:

• JavaScript enabled on client side
