Krypt

Krypt is a swiss-army knife for encoding, decoding, and hashing in the terminal.

Installation

Using cargo

cargo install krypt

Building from source

Requirements: - Rust (1.41 stable) - cargo

``` git clone git@github.com:Stupremee/krypt cd krypt

Just build the binary

cargo build --release

Install krypt

cargo install --path . ```

Usage

Hashing

```sh

hash stdin input and output hex representation

$ echo -n "hello world" | krypt -f hex hash sha256

b94d27b9934d3e08a52e52d7da7dabfac484efe37a5380ee9088f7ace2efcde9

output raw bytes to

-f raw is optional because the default format is raw

$ echo -n "hello world" | krypt -f raw hash sha256 | xxd

00000000: b94d 27b9 934d 3e08 a52e 52d7 da7d abfa .M'..M>...R..}.. 00000010: c484 efe3 7a53 80ee 9088 f7ac e2ef cde9 ....zS..........

output in hexdump format using hexyl

$ echo -n "hello world" | krypt -f hexdump hash sha256

┌────────┬─────────────────────────┬─────────────────────────┬────────┬────────┐ │00000000│ b9 4d 27 b9 93 4d 3e 08 ┊ a5 2e 52 d7 da 7d ab fa │×M'××M>•┊×.R××}××│ │00000010│ c4 84 ef e3 7a 53 80 ee ┊ 90 88 f7 ac e2 ef cd e9 │××××zS××┊××××××××│ └────────┴─────────────────────────┴─────────────────────────┴────────┴────────┘

use file as input

$ echo -n "hello world" > yourfile $ krypt -i yourfile -f hex hash sha256

b94d27b9934d3e08a52e52d7da7dabfac484efe37a5380ee9088f7ace2efcde9

hash raw bytes

$ echo -n "\xff" | krypt -f hex hash sha256

a8100ae6aa1940d0b663bb31cd466142ebbdbd5187131b92d93818987832eb89

use hex encoded data as input

$ echo "0xff" | krypt --hex-input -f hex hash sha256

a8100ae6aa1940d0b663bb31cd466142ebbdbd5187131b92d93818987832eb89

works also with files

$ echo "0xff" > yourfile $ krypt --hex-input -i yourfile -f hex hash sha256

a8100ae6aa1940d0b663bb31cd466142ebbdbd5187131b92d93818987832eb89 ```

Encoding

```sh

encode string to bsae64

$ echo "hello!" | krypt encode base64

aGVsbG8hCg==

decode data

$ echo "aGVsbG8hCg==" | krypt encode -d base64

hello!

encode raw bytes (the 0A is the newline character)

$ echo "\xaa\xbb\xcc" > foo $ krypt -i foo encode hex

AABBCC0A ```
