Hash key - anyone?

Hi
This may seem daft but I can't find a hash key anywhere on my Macbook - not even in special characters. As these are often used in passwords it would be useful to have it.
Can anyone help please?
AJ

Ok, I'm guessing # is what you mean by hash key?
If so, it's referred to as the number or pound key on a us keyboard and is shift-3. But, since that is likely £ for you, try opt-3 as that gives us £ on a US keyboard.
You can enable the keyboard viewer by opening Language and Text System Preferences, Input Sources, and check the Keyboard & Character Viewer. Then, check the show input menu in menu bar. Select Keyboard viewer from the menu. Now, hold down different combinations of modifier keys and the keyboard viewer will show what keys produce various characters.

UK iMac Keyboard . . . . Hash Key?

Morning folks.
If from the title you havent realised, Im from the UK.
A little over a year ago I purchased a 12inch ibook g4 and im loving it. now its time for me to turn my PC into a door stop (no really!). I waste far to much time on windows playing games I cant play on a mac.
How ever when I ordered my iBook impretty sure I selected a UK keyboard and when I got it it didnt have a Hash key (#). This is kind of a tricky objective to over come when your a web designer and programmer. How ever I manage, some how.
Can anyone confirm for me if a Ukmac with this option: "Keyboard & Mighty Mouse + Mac OS X" comes with a hash key.
Many thanks

Hi Adam,
Welcome to Apple Discussions!
The UK layout has the £ sign where the US has #.
To get the # with your UK layout, type option+3.
To get the £ with a US layout, type option+3.
If you ordered a UK iBook, as opposed to an International iBook, then you rightly got the £ model.
Tip:
In System Preferences > International > Input Menu,
you can enable any layout that you would wish to use. Enable the input menu in the menubar too, and the keyboard viewer/character palette, a very handy small flag to have in your status bar.
Enjoy your Mac!

No hash key to be seen

How do I find a hash key on a UK keyboard? - I am sure it is obvious to anyone otehr than me!

I can't find a way to get "Spanish" to show up in my character palete. IN my International pref settings the list shows English and Spanish. And I have it set to show input from both caracter palette and keybaord viewer. When I open Character Palette I see now reference to Spanish letters or chacters. The View popdown windown at top left shows Roman (?), Japanese and Korean. No listing of Spanish. (What is "roman"??) I'd like to delete the Japanese and Korean -- where's Spanish?!!?
The Category tap shows all TYPES of symples (math, arrows, crosses, digits, etc_. But again, no Spanish! What gives? -- david in KC

C++ programming (missing hash key)

My Mac Mini was supplied with an Apple keyboard. It's about 450mm x 100mm, made from brushed aluminium with flat, white keys. Unfortunately, there's no hash key AFAICT. This is going to be a problem for me since I'm a C++ programmer and the hash key is pretty important in C++ programming!
I found out that a hash symbol can be generated by using Option+3. However, this only seems to work for OS-X. I've dual installed Windows (using Boot Camp) but Option+3 doesn't work there.
Can anyone suggest an alternative keyboard that might offer a working hash key for both OS's? Or would a standard PC keyboard work?

Have you installed the Boot Camp drivers for Windows to match the hardware with the OS? Have you configured Windows to use a UK keyboard profile?
Just an idea for you. There is an entire Apple Discussion forum dedicated to Boot Camp and Windows.
Whereas, not everyone here with an Intel Mac mini has installed, tried to install or has experience with BC & Windows, everyone there has or at least has an interest. You may attract help more quickly there.
The Forums are at the bottom of the main Apple Discussions page under Windows Compatible Technology. Here is a link;

Generate Unique Hash Key in PL/SQL

I have a document that i want to send to certain customers. What I've decided to do is send the customer a link to the document that will be stored locally on our server. Obviously for security reasons i don't want to simply send the sequential doc ID allowing customers to change the query string to get other information.
What would be the best way in pl/sql to generate a unique hash key to include in the url? The key would have to be both unique and not easily edited by customers to view other documents.
Any help would be much appreciated.

I've been experimenting with SHA-1 and it works very well in producing a 40 character hash. My one concern is that for example hashing '1025' produces the following hash 'B74E9CAD775D997FC742B45E1BA7BD5295D63D13'.
Would someone not just simply be able to use SHA-1 to create a hash for '1026' (since i'm using a sequential number for my input) and consequently retrieve somebody elses information and leave my system vulnerable?
Might i be better off to encrytp the input?I thought the point was that the "user" would only be provided with the hash value as a reference to the document and they would not have a clue how to alter that hash value to another value in order to retrieve a different document. Surely they don't know that the hash value they have relates to '1025' so a) how would they know that they can obtain the hash for '1026' to get the next document and b) how would they go about creating their own hash values unless you somehow give them access to Oracle's DBMS_CRYPTO package?
If you really want to be sure then you could also also incorporate the date/time of the document into the string that you hash, so they would have to a) have access to the dbms_crpto package, b) know the filename and the date/time of the document and c) know what order to combine those things (and the format mask you've used on the date/time etc.) to provide the correct hash to obtain the document.
If you use encryption then you leave yourself open to decryption.
If you use hash then this is generally a 1 way mechanism, hence details are better hidden.
I think you'll find when it comes to things like password storage, most will use a 1 way hash (or similar) algorithm rather than an encrypted password so that the stored passwords can never be reverse engineered. Also, such password algorithms usually combine the username or some other feature to prevent two users with the same password getting the same hash value.

Hash key doesn't work :(

Guys this is doing my head in.
I am using a UK keyboard and a UK Macbook Pro 2008 (Late). I can't use a hash key at all using ALT + 3 or SHIFT + 3. It shows hash on they keyboard viewer but it never does output the icon on the screen
At the minute my only option is to use the US keyboard, but quite simply I don't as I have a UK physical keyboard. Any ideas?
Cheers

I've been struggling with this same problem for a while before realising that I'd mapped ALT+number to another application, specifically to change desktops using Spaces in OSX.
Having removed this new key binding, I can now use ALT+3 to create # for the first time in months; a classic case of operator error.
Just wondered if you'd checked similar settings which might ave over-ridden the default settings?
Good luck.

How can we see record hold by the hash key value for a lock held

Hi Experts ,
I remember there is function in SQL server where you can see record /column value of the hask held in locking ? please can you let me know the function name. we can provide hash key (bb00f5802873) and see the undelying data.

Thanks for this,
We have deadlock in our system on this key lock and wants to repro the scenario based on the key value,

Hash key on UK mac pro keyboard?

I'm an avid twitter user in need of a hash key! I have a UK keyboard and need to keep my £ sign. Alt, control or shift +3 don't produce a hash sign for me. Any ideas please?

Annoying isnt it?!? try Alt+3, should work well enough (FYI, I use it in Excel via VMware and its CTRLALT3)

SIMPLE QUESTION - HASH KEY - WHERE IS IT

I've had my MacBook Pro for 2 years and only just noticed the keyboard does NOT have a Hash key.
I need it now for some programming work.
Where is it? How do I invoke the hash character?

Linton Woodman wrote:

That may indicate you have a British keyboard. On that the # key is at Option/alt + 3.
If you have some keyboard other than US or British, let us know.

Hash key on MacBook

Hi,
When I'm developing web-pages, it is often useful to use the hash key. But I cannot find it on my MacBook keyboard layout. I am using the English keyboard. It is usually next to the apostrophe I find, but I cannot see it on the MacBook. Any thoughts?
Thanks in advance.

Try Alt+3

Finding the hash key on a wireless keyboard

I have recently purchased a wireless keyboard, can someone tell me how to find the hash key?

Press and hold the Alt key then 3.
Interesting; on my US keyboard, Option + 3 produces this: £
whereas Shift + 3 produces this: #

Nuisance calls: does pressing the hash key do anyt...

There are lots of internet hits on pressing your phone's hash key (#) repeatedly when you receive a nuisance call. Some say it confuses the calling company's telephony equipment, others that it removes your number from their list. Does the hash key in fact do anything useful, or is this just an urban myth?

Hi
As Ectophile says it "may" confuse the system but other than that it does not have any effect, my advice is to stay silent as the call centre equipment waits for a voice on the line before it connects an operator to you.

3DES decryption with SHA1 hashed key

Hello all,
I've been given the task of rewriting an existing VB application in Java, and one routine makes use of the Microsoft Cryptography API.
The VB code decrypts a string using TripleDES decryption, using a string key that's been hashed with a SHA1 has algorithm.
Most of the java DESede encryption/decryption examples I've worked through generate keys with a KeyGenerator instance, but I have not yet found any examples that use a key that's been SHA1 hashed.
My attempts at using a hashed byte[] array of my key phrase with a DESede Crypto instance always return a "wrong key size" error.
Can anyone provide some help? Example code fragments or anything would help.

Thanks for the reply, and you're right in that this might be a more appropriate question to ask on a VB forum or on a MS cryptography API forum.
Nevertheless, I've been able to make some headway on the VB side by getting the bytes of the SHA-1 hash map through some API calls.
The hex representation of the SHA-1 hashed keyword:
"3EC10CE885353DCD23B912860C2B91885CD3D6D1"
A keyword to use as a test:
"logins"
Hex representation of the 3DES encrypted result of "logins" using the hashed keyword:
"FB158A921E3C4CDB"
Currently, my problem is with the length of the key. As you pointed out, SHA is 20 bytes, while 3DES is looking for 24 bytes. I'll experiment with your suggested 2-key approach, but here's my test code at the moment:
import java.security.*;
import javax.crypto.*;
import javax.crypto.Cipher;
import javax.crypto.Mac;
import javax.crypto.SecretKey;
import javax.crypto.spec.DESedeKeySpec;
import javax.crypto.spec.SecretKeySpec;
public class EncryptionTest {
public static void main(String[] args) {
String hashedKey = "3EC10CE885353DCD23B912860C2B91885CD3D6D1";
String textToCode = "logins";
byte[] keyBytes = hexStringToBytes( hashedKey );
byte[] source = textToCode.getBytes();
SecretKey key = new SecretKeySpec(keyBytes, "DESede");
try {
Cipher cipher = Cipher.getInstance("DESede");
cipher.init(Cipher.ENCRYPT_MODE, key);
byte[] result = cipher.doFinal(source);
String sresult = hex( result );
System.out.println( result );
} catch ( NoSuchPaddingException e ) {
e.printStackTrace();
} catch ( BadPaddingException e ) {
e.printStackTrace();
} catch ( NoSuchAlgorithmException e ) {
e.printStackTrace();
} catch ( InvalidKeyException e ) {
e.printStackTrace();
} catch (IllegalBlockSizeException e ) {
e.printStackTrace();
static byte[] hexStringToBytes( String s ) {
int iLength = s.length();
int iBuff = iLength / 2;
byte[] buff = new byte[ iBuff ];
int j = 0;
for(int i = 0; i < iLength; i+=2) {
try {
String s1 = s.substring(i, i+2);
buff[j++] = (byte) Integer.parseInt(s1, 16);
} catch ( Exception e ) {
e.printStackTrace();
return buff;
static String hex(byte[] data) {
StringBuilder sb = new StringBuilder();
for (byte b : data) {
sb.append(Character.forDigit((b & 240) >> 4, 16));
sb.append(Character.forDigit((b & 15), 16));
return sb.toString();
}

Wireless Keyboard Hash key issue.

Hi. I have a bit of a problem with my brand new (UK version) wireless keyboard: I can't type the "hash" symbol that ought to come up with alt-3 (option-3). When I pull up the keyboard viewer and hold down alt, the "3" does indeed change to the hash symbol, but when I then hit "3" nothing appears. This is true in any application: Firefox, Safari, Word, Mail, even the Dashboard StickyNotes.
Can anyone think of a reason that my ability to type the hash might somehow have been switched off? All my software is up to date via Software Update. I'm puzzled and would be grateful for any advice.
(It's making life on Twitter pretty tedious...)

The "Use all F1 etc keys as standard function keys" tab isn't selected. It says "when this option is selected, press the Fn key to use the specal features printed on each key". Problem being there is no "Fn" key. So I suppose this option will just turn off the special function on these keys?
