DER ASCII is a small human-editable language to emit DER-like output. Its goal is to help create test inputs by taking an existing DER or BER structure, disassembling it into DER ASCII, making adjustments, and assembling back into DER. This avoids having to manually fix up all the length prefixes. As a bonus, it acts as a human-readable view for DER structures.

For the language specification, see language.txt.

This project provides two tools, ascii2der and der2ascii, to convert DER ASCII to a byte string and vice versa. To install them, run:

go get github.com/google/der-ascii/...
