Manage ASN1 (Abstract Syntax Notation One) structures. The main features of this library are: * on-line ASN1 structure management that doesn't require any C code file generation. * off-line ASN1 structure management with C code file generation containing an array. * DER (Distinguish Encoding Rules) encoding * no limits for INTEGER and ENUMERATED values . This package contains programs to encode, decode and parse asn1 data structures.
