muerte32crypt 1.0.3

Windows-native DPAPI encryption with a clean Python interface.

muerte32crypt

Windows-native DPAPI encryption using ctypes. Encrypt and decrypt strings, bytes, or files with optional entropy and descriptions. Includes TPM utilities, certificate handling, RSA, EC & Ed keys, symmetric ciphers, Twofish, and key management.

Usage example

from muerte32crypt.dpapi import encrypt_str, decrypt_str

encrypted = encrypt_str("my_secret_password", entropy="somesalt")
print(decrypt_str(encrypted, entropy="somesalt"))

from muerte32crypt.keymanagement import KeyManager

km = KeyManager()
km.generate_key("my_sym_key", 32)
key = km.get_key("my_sym_key")
print(key.hex())

priv, pub = km.generate_rsa_keypair("my_rsa_key")
pem = km.export_private_key_pem("my_rsa_key", passphrase=b"mypass")
print(pem.decode())

from muerte32crypt.certs import generate_self_signed_cert, get_cert_subject

cert, key = generate_self_signed_cert("example.com")
print(get_cert_subject(cert))
