Dear coders.

If you would not mind taking a look at this page...

http://www.licenturion.com/xp/fully-licensed-wpa.txt

If you see that the installation id is a string of digits, very long... e.g

234344-345656-898909-878766-567676-555655-454334-565556-77 etc

When the check digits are removed, it ends up as a 42 digit number, and this is represented as a byte array encoding of this, 17 bytes long.

How do i get the above long string of digits into its 17 byte representation?

I do not simply want a byte array the same lenght of the string (i.e. 41 digits) I need an actual byte array of 17 digits that represent the numer.

Basacaly, i need to be able to generate the byte array of the string above and vice versa (it may be a base-10 representation.

If no one can help, how can i do the following?

Have a byte array like

BYTE[] = {0x44, 0x34, 0x22, 0x47, 0x49, 0x78, 0x54, 0xf3, 0x2a, 0x44, 0x44, 0x28, 0x44, 0x83,
0x33, 0x22, 0x44}

17 bytes, to represent an encoding of a long number of forty something digits in a string of:

034333-495655-345444-090986-091232 etc....

Basacily as in the text above.
Thank you
Steve
