shep32 2.60.4

SHEP64 and SHEP72 key generation, encryption, signing, and CLI tooling

shep32

shep32 packages the SHEP64 and SHEP72 tooling into a PyPI-friendly layout with both a Python API and a console CLI.

What it includes

• SHEP64 primary key generation
• SHEP72 extended key generation
• Text and file encryption/decryption to .sh32
• Detached body/meta encryption mode
• Ed25519 public key derivation, signing, and verification
• Range generation and benchmark commands
• Interactive CLI mode

Install

pip install shep32

For local development:

pip install -e .

CLI entry points

After installation, both of these commands work:

shep32 --help
shep --help

Open the interactive menu:

shep32 start

Common commands

Generate a fresh random key:

shep32 key

Generate a deterministic key from text:

shep32 hash --text "hello"

Generate a deterministic key from an integer:

shep32 hash --value 12345

Generate an extended SHEP72 key:

shep32 hash --mode 1 --text "hello"

Generate a range:

shep32 range --start 0 --hashes 10

Encrypt text:

shep32 enc --text "secret" --out secret.sh32

Encrypt a file:

shep32 enc --file ./notes.txt

Decrypt a token file with a key file:

shep32 dec --file ./notes.sh32 --keyfile ./notes.pkey

Derive a public key:

shep32 pubkey --keyfile ./notes.pkey

Sign text:

shep32 sign --text "message" --keyfile ./notes.pkey

Verify a signature:

shep32 verify --text "message" --signature <signature> --public-key <publicKey>

Run a benchmark:

shep32 bench --hashes 1000 --compare

Python API

from shep32 import generateKey, encryptData, decryptData, signData, verifySignature

key = generateKey("hello", mode = 0)
cipher, usedKey = encryptData("secret", key)
plain = decryptData(cipher, usedKey)

sig = signData("message", usedKey)
ok = verifySignature("message", sig["signature"], sig["publicKey"])
