CipherDex

CipherDex is a powerful command-line toolkit for encryption, decryption, and cryptanalysis of classical ciphers.

Explore, analyze, and break classical ciphers directly from your terminal.

Installation

pip install cipherdex

Usage

Encrypt text

cipherdex encrypt --algo caesar "hello world" --key 3

Decrypt text

cipherdex decrypt --algo caesar "khoor zruog" --key 3

AES encrypt/decrypt

cipherdex encrypt --algo aes --key <BASE64_KEY> "hello world"
cipherdex decrypt --algo aes --key <BASE64_KEY> <BASE64_CIPHERTEXT>

AES-Password encrypt/decrypt (password-based)

cipherdex encrypt --algo aes-password --password "mypassword" "hello world"
cipherdex decrypt --algo aes-password --password "mypassword" <BASE64_CIPHERTEXT>

RSA encrypt/decrypt

cipherdex encrypt --algo rsa --pub-key-file pub.pem "secret message"
cipherdex decrypt --algo rsa --private-key-file priv.pem <BASE64_CIPHERTEXT>

Generate key

cipherdex generate-key --algo aes
cipherdex generate-key --algo rsa

Hash data

cipherdex hash --algo sha256 "hello world"
cipherdex hash --algo sha256 --file data.txt
cipherdex hash --algo bcrypt "password"
cipherdex hash --algo argon2 "password"

Analyze text

cipherdex analyze "khoor zruog"

Detect cipher

cipherdex detect "khoor zruog"

Bruteforce Caesar cipher

cipherdex bruteforce "khoor"
