What is MD5 and how to use it?
In cryptography, MD5 (Message-Digest algorithm 5) is a widely used cryptographic hash function with a 128-bit hash value. As an Internet standard (RFC 1321), MD5 has been employed in a wide variety of security applications, and is also commonly used to check the integrity of files. An MD5 hash is typically a 32-character hexadecimal number. Recently, a number of projects have created MD5 "rainbow tables" which are easily accessible online, and can be used to reverse many MD5 strings into their original meanings.
First, place the given MD5 checksum on the Clipboard (Ctrl C or Edit...Copy) Run the MD5 Check Utility (MD5.Exe) and this should automatically place the contents of the Clipboard in for you (Paste option). If not, please ensure that you have correctly copied the checksum to the Clipboard, and then click on the Paste button. You can also use the Paste facility for checking more than one MD5 checksum without the need to re-run MD5.Exe (simply copy the next desired checksum to the Clipboard and take the Paste option to refresh the box...then the Browse option).
