.PP
|
||||
The ASN.1 family of standards define a number of ways to encode data,
|
||||
including byte\-oriented (e.g., BER), bit\-oriented (e.g., PER), and
|
||||
textual (e.g., XER).
|
||||
Some encoding variants (e.g., DER) are just stricter variants of the
|
||||
more general encodings (e.g., BER).
|
||||
.PP
|
||||
The interoperability table below specifies which API functions can be
|
||||
used to exchange data in a compatible manner.
|
||||
If you need to \f[I]produce\f[] data conforming to the standard
|
||||
specified in the column 1, use the API function in the column 2.
|
||||
If you need to \f[I]process\f[] data conforming to the standard(s)
|
||||
specified in the column 3, use the API function specified in column 4.
