From the developer:
Abstract Syntax Notation One (ASN.1) Distinguished Encoding Rule (DER) encoded data is widely used in digital security protocols (i.e. X509 digital certificate). The encoded data is not readable by regular text editors. The Asn1Processor Library is designed to parse and modify ASN.1 DER encoded data. The ASN.1 Editor is a sample project that uses the Asn1Processor library to view and to edit DER encoded data.
