25. 这里需要注意的是在你加密的时候必须要对字符串进行转码才能得出结果,不转便会报:TypeError: Unicode-objects must be encoded before hashing错误 如果数据量很大,可以分块多次调用update(),最后计算的结果是一样的: import hashlib md5 = hashlib.md5() md5.update('123123
import hashlib # 原始数据 message = "This is an example message for MD5 hashing." # 创建MD5哈希对象 md5_hasher = hashlib.md5() # 更新哈希对象,传入待加密的字符串 md5_hasher.update(message.encode('utf-8')) # 获取哈希值 hex_digest = md5_hasher.hexdigest() print(f"原始消息:{message}"...

In the calculate_hash() method of the Blockchain class, calculate the hash of the current block by concatenating the block’s attributes (excluding the hash attribute) and using a hashing algorithm (such as SHA-256) to generate a hash value. In the is_chain_valid() method of the Blockch...
