history

Project history and usage

der-ascii is a small reversible text format and pair of tools for converting ASN.1 DER or BER data between bytes and a human-editable representation.

Project history

The project is hosted under Google's GitHub organization, but its README explicitly says it is not an official Google project.

Adoption history

Official install instructions use Go's module-aware install command, while the input package facts show availability through Homebrew and Nix.

How it is used

The documented workflow is to disassemble DER or BER with der2ascii, edit the textual representation, and reassemble it with ascii2der, especially for test inputs.

Why package nerds care

It is useful to package maintainers and security-tool developers because it makes binary DER and BER fixtures reviewable, editable, and round-trippable from the shell.

Timeline

Current: README documents ascii2der and der2ascii as the public tools.
Current: README documents backwards-compatibility intent for the command-line interface.
