Thanks for explaning the correct method.
Also it would be very much helpful if can provide me some algorithm
which takes some integer(max 4 bytes value) as input and should return
the length needed for ASN1 BER encoding.
Could any one help me in finding thos algorithm.
I did already in a separate email. I wrote
===
It would be very much useful
to me if u can provide me some algorithm which encode an ASN integer
If the integer is between -128 and +127, move the rightmost byte.
If the integer is between +128 and +32767, or between -129 and -32768,
move the rightmost two bytes.
Etc.
You can also just start from the left like this:
- examine the bytes from the left one at a time;
- if it's 0x00 or 0xFF, go to the next byte;
- if it isn't 0x00 or 0xFF, copy it and the rest of the bytes to its
right;
- if all you have is 0x0000000 or 0xFFFFFFFF, then copy the single
byte 0x00 or 0xFF.
