Can anyone point out what the advantage of using HMАC is?
For example, if I have a text T and a key K, I can use either HMAC-MD5 algorithm or Md5(T + K) to get a signature.
The Wikipedia article on HMAC gives a good explanation of this.
In the Security section of the same article it goes on to say:
So adding an HMAC to an MD5 hash would make it substantially more difficult to break via a rainbow table.
