[英]Linux command line SHA-256 hash different from online tools?
I was looking for a quick way to compute the SHA-256 hash of a password so I could upload some test data into a database that we are using Spring Security to authenticate against. 我正在寻找一种快速计算密码的SHA-256哈希的方法,这样我就可以将一些测试数据上传到我们使用Spring Security进行身份验证的数据库中。
First I found the linux utility sha256sum
and ran it again the password "admin" and got this result: 首先,我找到了linux实用程序sha256sum
并再次运行了密码“admin”并得到了这个结果:
fc8252c8dc55839967c58b9ad755a59b61b67c13227ddae4bd3f78a38bf394f7
Then I tried an couple online services (for fun): 然后我尝试了几个在线服务(为了好玩):
http://www.xorbin.com/tools/sha256-hash-calculator http://www.fileformat.info/tool/hash.htm?text=admin http://www.xorbin.com/tools/sha256-hash-calculator http://www.fileformat.info/tool/hash.htm?text=admin
and both gave me this very different result: 两者都给了我这个截然不同的结果:
8c6976e5b5410415bde908bd4dee15dfb167a9c873fc4bb8a81f6f2ab448a918
Why are they different and which is correct? 为什么它们不同,哪个是正确的?
I ran into this problem while doing something similar. 在做类似的事情时遇到了这个问题。
What I was doing was something like echo string | sha256sum
我在做什么就像echo string | sha256sum
echo string | sha256sum
, I think. echo string | sha256sum
,我想。
I'd get a different result when I ran this through the php hash generator. 当我通过php哈希生成器运行时,我会得到不同的结果。 The reason was because of the new line that echo added. 原因是由于回声添加的新线路。
I don't know if you're using echo but if you are try echo -n string | sha256num
我不知道你是否正在使用echo但是如果你正在尝试echo -n string | sha256num
echo -n string | sha256num
. echo -n string | sha256num
。
According to echo -n "admin" | shasum -a 256
根据echo -n "admin" | shasum -a 256
echo -n "admin" | shasum -a 256
on my Mac OS X, the later is correct. echo -n "admin" | shasum -a 256
在我的Mac OS X上,后者是正确的。 Note that you need to do echo -n
, otherwise there's a \\n
in the string that is hashed as well. 请注意,您需要执行echo -n
,否则字符串中的\\n
也会进行哈希处理。 Since shasum
is a Perl script, you might have it as well. 由于shasum
是一个Perl脚本,你也可以拥有它。 If so, try to use that. 如果是这样,请尝试使用它。
