## プロジェクトの歴史と使われ方

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.

### プロジェクトの歴史

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

### 採用の歴史

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

### 使われ方

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

### パッケージ好きにとっての重要性

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.

### タイムライン

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

### Related projects

- ASN.1, DER, BER, Go command-line tooling.
