ASN.1 BER编码

Question

1 syntax. when i am encoding this syntax to BER, not providing correct results.

i am using OSS ASN.1 Stdio to compile the asn.1 syntax

SignDoc DEFINITIONS AUTOMATIC TAGS ::= BEGIN

OneSignature ::= SEQUENCE {
signTime UTCTime,
signature BIT STRING,
certificate BIT STRING
}


first-Doc OneSignature ::={

        signTime "130223064540Z",
        signature '0111010001100101011100110111010000100000'B,
        certificate '0111010001100101011100110111010000100000'B

}

  END

and BER Encoding result is :

30 1F
   80 0D 3133303232333036343534305A
   81 06 007465737420
   82 06 007465737420

Is this is correct result ?

we require the result of BER encoding is :

30 1F
   23 0D 3133303232333036343534305A
   03 06 007465737420
   03 06 007465737420

Please provide the suggestion.

Thanks

You should send your questions about the OSS Tools directly to OSS Technical support (support@oss.com). In this case, I suspect if you remove "AUTOMATIC TAGS" at the top of the ASN.1 module, you will get the results you are looking for.
