[OTR-dev] A C# lib

[alex323]

I think I know what I need to do now.. Do I need to insert the length of 
p, q, g, and e seperately? So if:

    p.Length = 12
    q.Length = 34
    g.Length = 56
    e.Length = 7890

i'd have my array look like this:

    [4]   = 0 /* It's 4 bytes per MPI */
    [5]   = 0
    [6]   = 0
    [7]   = 12
    [8]   = 0
    [9]   = 0
    [10] = 0
    [11] = 34
    [12] = 0
    [13] = 0
    [14] = 0
    [15] = 56
    [16] = 0
    [17] = 0
    [18] = 90 /* Big-Endian right? */
    [19] = 78

Please correct me if I am wrong :)

Regards,
Alex
