[quote user="subhajits"]decodehexstring(md5hash("jit")) returns ";n�S��,��F�" instead of "jit".[/quote]

decodehexstring() and md5hash() are completely different functions for different purposes. So, these functions never do the opposite of the other.

md5hash()

This function will return the 128-bit digest of the input string in a hex format so that the 128 bit can be easily represented with just 32 characters.

decodehexstring()

This function accepts a hex string and returns the equivalent text.
- Eg. if the hex string is 5E4B31 then it will be separated into pairs of 2 characters (HEX CODE) and the text equivalent for the corresponding hex code will be returned. For this example the output will be ^K1
  - 5E - ^
  - 4B - K
  - 31 - 1

Thanks,
