从Linux命令行生成sha256 [英] Generating a sha256 from the Linux command line

问题描述

我知道字符串"foobar"使用以下命令生成SHA 256哈希c3ab8ff13720e8ad9047dd39466b3c8974e592c2fa383d4a3960714caef0c4f2 http://hash.online-convert.com/sha256-generator

I know the string "foobar" generates the SHA 256 hash c3ab8ff13720e8ad9047dd39466b3c8974e592c2fa383d4a3960714caef0c4f2 using http://hash.online-convert.com/sha256-generator

但是命令行外壳:

hendry@x201 ~$ echo foobar | sha256sum 
aec070645fe53ee3b3763059376134f058cc337247c978add178b6ccdfb0019f  -

生成另一个哈希.我想念什么?

Generates a different hash. What am I missing?

推荐答案

echo通常将输出换行符，并用-n禁止换行.试试这个:

echo will normally output a newline, which is suppressed with -n. Try this:

echo -n foobar | sha256sum
