This Tcl script may be used to extract MIB, PIB and ASN.1 modules from an RFC document. Unlike most extractors, this script is smart enough to recognize ASN.1-style comments prior to or within the module header, use of the "TagDefaults" part of the module header (not used by MIB modules),... Platforms: *nix

A free utility that displays the ASN.1 structure of a BER-encoded file. ViewBer can be used to view the contents of PEM and DER encoded X.509 certificates, PKCS#12, PKCS#10, CSR files, PKCS#7, PKCS#8, etc. ViewBer supports the recursive decoding of OCTET STRING and BIT STRING objects, and... Platforms: Mac

A 100% pure Java Swing ASN.1 analysis utility for inspecting arbitrary BER-encoded data files. It allows inspection of data with unknown structure, can drill down to any nesting level and allows to interpret embedded OCTET STRING data recursively. Platforms: Windows, Mac, Linux

JAC (Java Asn1 Compiler) is a tool for you if you want to (1)parse your asn1 file (2)create .java classes and (3)encode/decode instances of your classes. Just forget all asn1 byte streams, and take the advantage of OOP! BER, CER and DER are all supported Platforms: Windows, Mac, Linux

A fast, comprehensive, and easy-to-use Java API for communicating with LDAP directory servers and performing related tasks like reading and writing LDIF, encoding and decoding data using base64 and ASN.1 BER, and performing secure communication. Platforms: Windows, Mac, Linux

Free and open-source pyasn1 library makes it easier for programmers and network engineers to develop, debug and experiment with ASN.1-based protocols using Python programming language as a tool. Abstract Syntax Notation One (ASN.1) is a set of ITU standards concered with provisioning... Platforms: *nix

bsnmp is a miniSNMP daemon. For a couple of projects that involved controlling software on a couple of machines from a single controlling machine I decided to use SNMP. After looking at several available SNMP implementations I started to implement my own SNMP stuff, because what was available was... Platforms: *nix

Whois Proxy provides a CGI or command line whois proxy tool. Whois Proxy is a Perl whois tool for looking up the owners, technical contacts, abuse desk, IP address, NIC handle, or ASN of any domain on the internet. A complete rewrite of the GeekTools whois proxy, it also runs either as a Web... Platforms: *nix

PDF::Reuse::Tutorial is a Perl module that will teach you how to produce PDF-files with PDF::Reuse. In this tutorial I will show some aspects of PDF::Reuse, so you should be able to use it in your own programs. Most important is how to produce and reuse PDF-code, and then if you are interested,...
