Message Digest of char array

I'm trying to create a message digest for a password, which is stored as a char array.

Currently, I'm doing something like this:

char [] password ;
...
MessageDigest md5=MessageDigest.getInstance("MD5");
md5.update(new String(password).getBytes("UTF8"));
byte [] md = md5.digest();

Which works. However, converting it to a string [in order to get a byte array for it] defeats the entire point of storing the password as a char array in the first place..

So is there a direct way of achieving this, without incorporating java.lang.String?


Thanks

The password shouldn't be stored anywhere client-side, in whatever form

A character is 2 bytes long and a byte is 1 byte long.. so if you want to convert a char[] to a byte[], then your solution seems best.
The message digest works on bytes only anyway..

If you plump for low security and store it client-side, then of course you could store it as UTF byte[]

You're storing it as a byte[] so it looks fine to me.
