asn1c

Modern ASN.1 to C compiler

The asn1c compiles ASN.1 (Abstract Syntax Notation One) specifications into the C source code. This compiler supports automatic constraints checking code generation, parametrization, basic support for Information Object Classes. The produced C code contains the codecs for BER/DER/CER/PER/XER encoding rules. See asn1c-usage.pdf and asn1c(1) manual page for details.
