问题描述
如果我从 Mac 调用命令
If I invoke the command from Mac
echo hello | shasum -a 256
或来自 ubuntu
echo hello | sha256sum
然后我得到以下结果
5891b5b522d5df086d0ff0b110fbd9d21bb4fc7163af34d08286a2e846f6be03 -
我注意到末尾有破折号.
I notice there is dash at the end.
但是当我使用 Python hashlib 或 Java java.security.MessageDigest 时,它们给我的结果相同,如下所示:
But when I use Python hashlib or Java java.security.MessageDigest, they give me the same result as follows:
2cf24dba5fb0a30e26e83b2ac5b9e29e1b161e5c1fa7425e73043362938b9824
那么,谁能指出我哪里弄错了?
So, could anyone point out where I got it wrong please?
谢谢.
Python:
>>> import hashlib >>> hashlib.sha256("hello").hexdigest()
Java:
MessageDigest md = MessageDigest.getInstance("SHA-256"); String text = "hello"; md.update(text.getBytes("UTF-8")); byte[] digest = md.digest(); StringBuffer sb = new StringBuffer(); for (int i = 0; i < digest.length; i++) { sb.append(String.format("%02x", digest[i] & 0xFF)) } System.out.println(sb.toString());
推荐答案
echo 命令正在为您的字符串添加尾随换行符.试试:
The echo commands are adding a trailing newline to your string. Try:
hashlib.sha256("hello ").hexdigest()
