异或运算在很多密码学算法中都有不同程度的应用,其运算特定在于一个数和另一个数连续异或两次仍得到原来的数。在实际使用中,因为要加密的信息和所使用的密钥在大多数情况下是不等长的,所以经常需要循环使用密钥。 def crypt1(source, key): '''source是要加密或解密的字符串,key是密钥字符串''' ...
# 使用后量子加密算法加密数据 ciphertext = encrypt(public_key, plaintext) # 解密数据 decrypted_text = decrypt(private_key, ciphertext) # 验证解密后数据是否正确 assert plaintext == decrypted_text 此外,除了加密算法本身的更新换代,未来的加密技术还需关注硬件加速、跨平台兼容性、加密效率以及隐私保护等...
