如何在python代码中自动识别加密最佳实践？

import hashlib

def auto_detect_best_practice(plaintext, ciphertexts):
    algorithms = ['md5', 'sha1', 'sha256']  # 加载常见的加密算法

    best_algorithm = ''
    best_score = 0

    for algorithm in algorithms:
        encrypted = hashlib.new(algorithm)
        encrypted.update(plaintext.encode('utf-8'))
        encrypted_text = encrypted.hexdigest()

        score = sum(1 for ciphertext in ciphertexts if ciphertext == encrypted_text)
        
        if score > best_score:
            best_score = score
            best_algorithm = algorithm

    return best_algorithm

# 测试代码
plaintext = 'Hello, World!'
ciphertexts = ['2ef7bde608ce5404e97d5f042f95f89f1c232871', 
               'db8ac1c259eb89d4a131b253bacfca5f319d54f2', 
               '943a702d06f34599aee1f8da8ef9f7296031d699']  # 样本数据集

best_algorithm = auto_detect_best_practice(plaintext, ciphertexts)
print('最佳实践加密算法：', best_algorithm)
