AES Encrypt¶
Overview¶
Advanced Encryption Standard (AES) is a U.S. Federal Information Processing Standard (FIPS). It was selected after a 5-year process where 15 competing designs were evaluated.
Status¶
| Field | Value |
|---|---|
| Implementation | Partial |
| Parity | Compatible |
| Availability | Available |
| Input requirement | Required |
| Features | none |
| Side effects | [] |
| Deterministic | true |
Input¶
Declared input type: Bytes.
Output¶
Declared output type: Bytes. Redirect stdout or use --output-file for exact binary bytes.
Arguments¶
| # | Argument | Type | Required | Default | Allowed | Sensitive | Description |
|---|---|---|---|---|---|---|---|
| 1 | Key | Bytes |
yes | <empty> |
— | yes | Encryption key (16, 24, or 32 bytes) |
| 2 | IV | Bytes |
no | <empty> |
— | no | Initialization Vector (16 bytes, optional, defaults to null) |
| 3 | Mode | Enum |
no | CBC |
CBC, CFB, OFB, CTR, GCM, ECB | no | Cipher mode (CBC, CFB, OFB, CTR, GCM, ECB) |
| 4 | Input | Enum |
no | Raw |
Raw, Hex | no | Input encoding (Raw, Hex) |
| 5 | Output | Enum |
no | Hex |
Hex, Raw | no | Output encoding (Hex, Raw) |
| 6 | Additional Authenticated Data | Bytes |
no | <empty> |
— | no | AAD for GCM mode (optional) |
Implementation¶
The implementation is in src/operations/aes_encrypt.rs and declares Bytes input and Bytes output. The operation module owns conversion and domain-error rules; registry resolution, argument validation, input-requirement enforcement, tracing, and output validation are performed by rxchef::execution.
Command-line use¶
This operation requires input. Supply literal UTF-8 with --input, exact bytes with --input-file, or pipe bytes on stdin.
rxchef run "AES Encrypt" --input-file input.bin --output-file output.bin
Arguments may be supplied positionally in the table order or by name with repeatable --arg NAME=VALUE. Omitted optional arguments use the documented defaults.
Pipeline use¶
Place the operation anywhere a Bytes value is valid. Its Bytes result becomes the next step's input. Compact syntax uses the operation name followed by comma-separated arguments; JSON/YAML recipes use an op field and an args array.
Error conditions¶
Schema violations are rejected before the operation runs. Malformed input, unsupported parameter combinations, unavailable optional backends, and domain processing failures produce structured errors and a non-zero CLI status; partial output is never reported as success.
CyberChef compatibility¶
Parity status: Compatible. Unknown records an unassessed compatibility claim; it does not imply equality or incompatibility.
Security considerations¶
Declared side effects: []. Treat parser inputs as untrusted and apply execution limits to large data. Arguments marked sensitive in the schema are redacted from metadata-aware History displays.
