Hi Stephan, You said "let us know if the documentation should be improved." .. Today I realized that, in the BEROutputStream class some methods are not implemented (encodeSequence(..), encodeSet(..), encodeExplicit(..), etc.) It is only writing "Is not implemented yet" in these methods. I am not sure but I think this means Asn.1 Framework does not fully support BER encoding/decoding.. Is it true? :( I need BER processing.. If true, it is not writing in the documentation .. (If I am right, maybe you should write this missing part information in the documentation)
You said "... I think that there should be a number of existing parsers for ASN.1" Yes, there are some open source fully compilers about Asn.1 and they are very useful. But all of them are DER supported. I could not find a complete BER compiler... Thanks for your concern..

Hi Fatih, There is no "parser text'" that reads ASN.1 notation in the ASN.1 framework.

The ASN.1 is used for quite long time and I think that there should be a number of existing parsers for ASN.1 (it may be worth to find and try them first).

If ok, can you show me where it is ..? ____________________________________________________________________________________ Shape Yahoo! in your own image.
