Enhancements
Bug fixes
-
The display is truncated when using a JVM 1.5 and upper.

Summary of changes
Asn1Browser
v4.4.2 brings the following changes :
Enhancements
- If the smart value of a component contains new lines (\r or \n characters),
the browser displays it on several lines. A new option "Expand smart
value" can turn this off.

Asn1Browser
v4.3.3 brings the following changes :
Enhancements
- The browser is able to load plugins built with Asn1Compiler
v3. The Professional package includes the Asn1Compiler
v3.
Bug fixes
Asn1Browser
v4.3.2 brings the following changes :
Enhancements
- The OneByteDiscriminatorFilter allows specifying a choice of discriminators
using '|' to separate them.
- The decoder defined by the protocol encoding rules may be defined as non
validating so that the constraints defined in the ASN.1 syntax are not checked
after the decoding pass. By default the decoder is validating.
Asn1Browser
v4.3.1 brings the following changes :
Enhancements
Bug fixes
- When there is one single protocol which filter is considered as ambiguous
(typically no filter) the analyzer doesn't give the full error diagnostic.
This is fixed by considering that if there is one protocol only then all errors
are to be given by the analyzer whatever the filter maybe.
Asn1Browser
v4.3.0 brings the following changes :
- The packet capture mode now uses WinPcap3.0 (see notes
for packet capture mode).
- Filtering features of packet capture are based on the filtering features
of the WinPcap3.0 layer. This allows a much powerful way to filter packets.
Filter configuration within a file disappears and can be removed from your
computer after building the equivalent new filters.
- WARNING: all existing profiles files need to be modified to be handled
by this new version. You have to replace all existing strings all existing
strings "com.unigone.business.beans" need to be replaced
by "com.unigone.asn1Browser". If ever you were using batch
files launching the Java class Asn1Browser, this class no longer stands in
the com.unigone.application.asn1Browser package but in the com.unigone.asn1Browser
package. Thus "com.unigone.application" shall be replaced
by "com.unigone".
- Protocols chaining logic (when several protocols are defined for the same
profile with identical filters) has been a bit modified. See Protocol
decodings for more information.
- Fix: message filtering after a packet capture may lead to heavy memory
consumption when PDUs are big and broken in several packets.
Asn1Browser
v4.2.1 brings the following changes :
- The definition of ignored messages of a Message Filter accepts the wildcard
"*" to specify only the start of the message to ignore.
- A configurable Message Filter LengthHeaderFilter has been added. It allows
configuration of a filter defining bytes to be ignored, size of length, ignorable
first bytes in the PDU.
Asn1Browser
v4.2.0 brings the following changes :
- The plugins (also known as Asn1API
for Asn1Browser) can now be downloaded from uniGone's
website through the "Plugins" menu.
Asn1Browser
v4.1.2 brings the following changes :
- Filters in packet capture mode allow couples of IP addresses which restrict
the number of analyzed packets to the minimum required.
- A filter in packet capture mode is saved and associated to the current profile
(if any). It is then loaded at the next opening.
- SIP packets can be analyzed (when no ASN1 profile is defined) in the packet
capture mode.
- Fix: in packet mode, even if the protocol filter was not fitting, pdus
were attempted to be decoded and displayed in error (the right protocol was
displayed follwoed by error pdus)
Asn1Browser
v4.1.1 brings the following changes :
- More information is given when a decoding fails (type is displayed with
already decoded material)
- A Message Filter can ignore some messages (in order the header length filtering
technic is not broken by establishment or synchronization bytes sequences
that may be sent by applications)
Asn1Browser
v4.1.0 brings the following changes :
- It's possible to open several record files during a "record session".
- Several PER encoded PDUs may be displayed even if there is no delimiter
between them.
- Profile and decoding errors are displayed in a log window.
- The auto scroll mode allows to automatically select the first PDU of the
next record file read.
- The "maximun PDU in memory" option is saved to persistent storage
for subsequent reuse.
Asn1Browser
v4.0.1 brings the following changes :
- It's possible to add several record files in a "record session"
(for the same profile).
- the first PDU automatically selected in the view panel.
- Fix: bad left margin with printing function. Use Java 1.2 Printing API.
Asn1Browser
v4.0.0 brings the following changes :
- New useful feature: the "packet capturer" mode which enables
reading data from a network device.
Note: this work uses Keita Fujii's "Jpcap" and we thank him much
for writing the JNI source code for interfacing WinPcap (Windows) and libpcap
(unix). The requirements are WinPcap2.3 on Windows and libpcap on unix (see
installation).
- New protocol filters: OneByteDiscriminatorFilter and FixedLengthHeaderFilter
which allow easier configuration for specific protocols.
Asn1Browser
v3.1.4 brings the following changes :
- Reading text log file: accept hexadecimal character with no separator.
- Fix: enable CTRL-C with jre1.4.1 to copy pdu in the clipboard.
- Fix: text file filter can read log file when: a pdu is defined on one
line ; a line (with a second pdu) can immediately follow a first line (with
a first pdu).
Asn1Browser
v3.1.3 brings the following changes :
- Fix: appropriate decoder error is given in the pdu panel (it was only
correct in the asb_trace.txt file).
Asn1Browser
v3.1.2 brings the following changes :
- the message filter "SinglePduFilter" used with a binary file filter
allows to read quickly big binary files.
- the message panel expands by default only the first 50 nodes of the ASN.1
tree in order to display quickly big PDUs.
Asn1Browser
v3.1.2 brings the following changes :
- the runtime (decoding primitives for the basic types according to encoding
rules) is now embedded in the Asn1API
for Asn1Browser. The same version of Asn1Browser
can use Asn1API
including different versions of the runtime.
- the profile definition is enhanced by the "protocol definition".
It identifies the abstract syntax PDU and the encoding rules needed to decode
ASN.1 data. For example the CSTA protocol uses the ROSE and the ACSE protocols :
one protocol definition identifies the ROSE abstract syntax and another one
identifies the ACSE abstract syntax .
- the profile definition is enhanced by the "display definition".
By default Asn1Browser
displays the root node of the decoded PDU in the "message panel".
To display another node you have to describe it in a display definition.
