asn1kit

asn1kit is an ASN.1 library written for Ruby.

asn1kit parses a subset of the ASN.1:2015 [see below for what is supported] and supports encoding of the BER (Basic Encoding Rules) and DER (Distinguished Encoding Rules).

What is supported by ASN1Kit

• Compiling ASN.1 module definition into Ruby objects
• BER/DER decoding and DER encoding
• TBA

The level of support is sufficient to compile and process most of the PKIX modules.

What is not supported by ASN1Kit

• Constraints are not supported except the SizeConstraint.
• XML value notation is not supported.
• TBA

How does the compiler work

The most part of the compiler is available in lib/asn1kit/parse.ry and lib/asn1kit/compile.rb.
