Indeed there many hashing utilities available online. However, none seem to support the hashing of a string that has been encoded in Unicode. For example, an ascii string in hex looks like this:
Code:
hello= 68 65 6C 6C 6F
whereas a Unicode string looks like this:
Code:
hello= 68 00 65 00 6C 00 6C 00 6F 00
When they are hashed, naturally they will result in different values. Hashing a Unicode encoded string will increase the security of the hash since most hash/password cracking utilities do not support Unicode encoding.
