rust-aes

An AES implementation in Rust.

Compiling

The code can be compiled with cargo. Users may install Cargo with rustup to establish a Rust compiling and running environment.

With cargo installed, compiling is simply

cargo build

and the resulting binary lays in /target/debug/aes.

The software speed may benefit from a release mode (optimizations).

cargo build --release

The resulting binary lays in /target/release/aes.

Running

aes 0.1.0
Yuze Fu <i@xfox.me>

USAGE:
    aes [FLAGS] [OPTIONS] --op <op> --mode <mode> [ARGS]

ARGS:
    <input>     Input file name, use a `-` for standard input [default: -]
    <output>    Output file name, use a `-` for standard output [default: -]

FLAGS:
    -h, --help       Prints help information
    -a, --hex        Indicates input and output are hex strings
    -v, --verbose    Log verbosity. May be used multiple times
    -V, --version    Prints version information

OPTIONS:
    -i, --iv <iv>        IV in hex format [default: -]
    -k, --key <key>      Key in hex format [default: -]
    -m, --mode <mode>    AES / Rijndael Modes
    -o, --op <op>        Operation mode, `encrypt` or `decrypt`

For example,

# AES-128-CBC with PKCS7 padding
#                       key                                 iv                                enc/dec
./aes -m aes-128-cbc -k 2b7e151628aed2a6abf7158809cf4f3c -i ae2d8a571e03ac9c9eb76fac45af8e51 -o enc p.txt c.aes
./aes -m aes-128-cbc -k 2b7e151628aed2a6abf7158809cf4f3c -i ae2d8a571e03ac9c9eb76fac45af8e51 -o dec c.aes p.txt
