Hello
I have a doubt about the ASN.1/BER encoding and decoding.
The ASN specification does not say anything about length of any data type. So it is
dependent on the implementation on how to limit it.
Say there is an INTEGER data type for some value in some PROTO protocol definition
which has a value that occupies 10 octets. The BER encoding would simply put the tag
for INTEGER, length = 10 and value = value for those octets. But how would the
compiler handle this thing. On what rules would the physical implementation limit the
size of the INTEGER. Also if it is for the compiler to decide this, then in the
absence of any general specification for limiting the length, if there are two
different compilers doing encoding and decoding at different ends and if the encoding
and decoing follows different rules to limit the integer, then how would both sides
decides out on this.
I think that I have missed out on some part of the specification that talks about
this.
