## プロジェクトの歴史と使われ方

AESCrypt is a small stream encryption and decryption utility for shell-script workflows. The official homepage describes aescrypt and aesget as standard-input filters using Rijndael in CFB-128 mode, with keys supplied from a key file or stdin.

### プロジェクトの歴史

The project belongs to the early AES transition period. The official page says Eric Lee Green wrote AESCrypt, and Randy Kaelber modified it to use Rijndael rather than Twofish while adding larger key sizes.

The homepage is also a time capsule of early-2000s open-source cryptography distribution: SourceForge hosting, source tarballs, a companion Ruby implementation, and a visible export-control reminder from December 2000. The page was last modified on 2002-09-17, leaving the tool with a deliberately stable, small surface area.

### 採用の歴史

AESCrypt was explicitly framed as a component for scripts, not as a full encryption product. The homepage says keychain management, public-key signatures, and larger policy concerns are expected to happen outside the program, which made the tool easy to compose in shell workflows.

The page also warns that applications built from open-source encryption components had their own export-control responsibilities. That notice is useful adoption context: AESCrypt was expected to be used inside larger applications or scripted systems, not only run by hand.

### 使われ方

The documented commands are aescrypt -k keyfile [-s 128|192|256] and aesget -k keyfile [-s 128|192|256]. The program encrypts or decrypts stdin, uses /dev/urandom to create a salt, prepends the salt while encrypting, and strips it while decrypting.

The key-file format is intentionally simple: a line beginning with kk= followed by hex key data. The homepage also documents reading the hex-coded key from stdin when the key file is -, while warning that this mode is less forgiving about exact key length.

### パッケージ好きにとっての重要性

AESCrypt is package-nerd archaeology: a compact AES-era Unix filter with SourceForge hosting, script-first ergonomics, and a design that avoids becoming a full key-management system.

It is useful to know because package repositories often preserve compatibility tools for old shell workflows even when newer designs steer users toward age, GnuPG, OpenSSL, or platform-native encrypted storage.

### タイムライン
