Parse ASN.1 encoding using Java
0
How can I read an ASN.1 file using Java when the file has this syntax:
Tagged[6]IMPLICIT
Sequence
Tagged[0]IMPLICIT
OCTET STRING[3](UGW)
Tagged[1]IMPLICIT
OCTET STRING[5](nair1)
Tagged[3]IMPLICIT
OCTET STRING[13](6430408182034)
Tagged[5]IMPLICIT
OCTET STRING[19](201211113336+0300)
Tagged[6]IMPLIIT
OCTET STRING[5](nair1)

While ASN.1 is related to security, your question is not a security question as it is entirely about programming.

Then feel free to ask a new question when you get to the next steps :) -- I agree with Androl that this question is purely programming. I'm voting to migrate to Stack Overflow where you'll get a better answer.

ASN.1 definition of yours looks mistaken. I would suggest correcting it as below :
My-Schema DEFINITIONS IMPLICIT TAGS ::=
BEGIN
MySequence ::= SEQUENCE
{
str1 OCTET STRING (SIZE(1..50)),
str2 OCTET STRING (SIZE(1..50)),
str3 OCTET STRING (SIZE(1..50)),
str4 OCTET STRING (SIZE(1..50)),
str5 OCTET STRING (SIZE(1..50))
}
END
It can be easily encoded using bountycastle ASN.1 API
import org.bouncycastle.asn1.*;
ASN1EncodableVector v = new ASN1EncodableVector();
v.add(new DEROctetString("str1".getBytes()));
v.add(new DEROctetString("str2".getBytes()));
v.add(new DEROctetString("str3".getBytes()));
v.add(new DEROctetString("str4".getBytes()));
byte encoded = new DERSequence(v).getEncoded();
