MacOS 中如何使用 md5sum 命令 2018-09-06 Liunx 中 md5sum 命令非常强大,加密和校对数据的 md5 都非常方便,MacOS 中没有安装该应用,而是默认安装了 md5 命令。. Md5sum allows you to verify that downloaded Shorten (.shn) files are not corrupted or otherwise unusable before you burn them to disc or host them on your file.
MD5 file is a MD5 Checksum. The MD5 algorithm, created by Ronald Rivest, is a way to sign a file to verify its contents mathematically. The hash consists of a 128-bit (16-byte) checksum - also known as a digest - that is generated cryptographically by using the contents of the file. MD5 utilities are available for Windows and Linux and Mac. Most Linux installations provide an md5sum command for calculating MD5 message digests.
The md5sum program is used to calculate and verify 128-bit MD5 hashes. This program is installed by default in most Unix, Linux, and Unix-like operating systems including BSD. Mac OS X is a BSD variant and it also includes the md5sum program. However, the program is called md5 instead of md5sum and outputs an MD5 checksum in a different format than the standard md5sum program.
Here's what the standard md5sum output looks like:
