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

There may be something in the GMP Bignum Library that can help you. Try searching the Internet for GMP C# bindings.

If I wanted to do this I probably would download the source code mentioned in the document, open up main.c, read it, find that the DecodeInstID function implements the algorithm, and then translate that into C#. Is this what you did, but then forgot? Alan.

Thank you i will try that, However, there was a simple block of code i found but i cannot find it. Is there some code that will convert/encode a byte array as a BASE-10 encoding, and one to decode. I can find many that will encode my byte array to represent base 24, base 32 or HEX but not a string of digits (base 10) Thank you Steve

Yes but it has been so long i have forgot my c and i tried that but cant figure it out. Steve
