SUPPORTED COINS: BTC, ETH, BCH, LTC, DOGE, DASH, XRP, SOL, TON

Installation

pip install cryptowall

Usage

import cryptowall as cw
cw.create_wallet("BCH", "VeryStrongPassword", "./tmp")

Functions

• generate_hex_private_key()
  Generate a cryptographically secure random 32-byte private key.
  Returns a 64-character hex string valid for all supported coins.
• hex_to_wif(hex_priv: str, coin: str, compressed: bool)
  Convert hex private key to Wallet Import Format (WIF) for BTC, BCH, LTC, DOGE, DASH.
• convert_private_key(hex_priv: str, coin: str)
  Convert a hex private key to the native format(s) used by coin.
  Returns a dict with at least 'hex' and coin-specific format keys.
• generate_rsa_keypair(key_size: int)
  Generate an RSA key pair.
  Returns (pem_private_key, pem_public_key) as PEM strings.
• encrypt_private_key(hex_priv: str, password: str)
  Encrypt a hex private key using a hybrid RSA plus AES-GCM scheme:
  • Derive a 256-bit AES key from password via PBKDF2-HMAC-SHA256,
  • Encrypt the private key bytes with AES-256-GCM,
  • Generate a fresh 2048-bit RSA key pair,
  • RSA-OAEP encrypt the AES key plus salt together.
    Returns a dict with all material needed for decryption except the RSA private key, which the caller must store securely.
• decrypt_private_key(encrypted: Dict[str, str], password: str)
  Reverse of encrypt_private_key, encrypted must be the dict returned by encrypt_private_key.
  Returns the hex private key string.
• generate_public_key_and_address(hex_priv: str, coin: str)
  Derive the public key and wallet address for coin from a hex private key.
  Returns a dict with 'public_key' and 'address' (plus any extras).
• save_wallet_to_json(coin: str, hex_priv: str, password: str, output_path: str)
  Full pipeline:
  • Encrypt the hex private key,
  • Derive public key and address,
  • Write JSON file with public key, address, encrypted private key.
    Returns the path of the written JSON file.
    The RSA private key (required for decryption) is stored in a separate _rsa_private_key.pem file.
• create_wallet(coin: str, password: str, output_dir: str)
  Generate a complete wallet for coin:
  • Random private key,
  • All key formats,
  • Public key and address,
  • Encrypted private key,
  • Saved JSON and PEM files.
    Returns a summary dict.
