## 项目历史与用法

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.

### 项目历史

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

### 采用历史

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

### 使用方式

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

### 为什么软件包爱好者会关心

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.

### 时间线

- 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.
