cryptik CLI

A simple and fast CLI tool for asymmetric encryption, decryption, key generation, and signing — written in Go using the Cobra framework.

---

Installation

go install github.com/petqoo/cryptik@latest

Or build from source:

git clone https://github.com/petqoo/cryptik.git
cd cryptik
go build -o cryptik

Usage

cryptik [command] [subcommand] [flags]

Examples

Key Generation (RSA)

Generate RSA keypair and output as PEM files:

cryptik asym keygen --type rsa --bits 2048 --out ./keys

---

Asymmetric Encryption

Encrypt plaintext using a public key:

cryptik asym encrypt --input "secret message" --pubkey ./keys/public.pem
# or from file
cryptik asym encrypt --file ./secret.txt --pubkey ./keys/public.pem

Decrypt ciphertext using a private key:

cryptik asym decrypt --file ./secret.enc --privkey ./keys/private.pem

---

Asymmetric Signing

Sign a message or file using a private key:

cryptik asym sign --input "important data" --privkey ./keys/private.pem
# or from file
cryptik asym sign --file ./data.txt --privkey ./keys/private.pem

Verify a signature using a public key:

cryptik asym verify --input "important data" --pubkey ./keys/public.pem --signature ./sig.bin

---
