Is there something easy I'm just missing?

SHA 256 Different Result

If I invoke the command from Mac echo hello | shasum -a 256 or from ubuntu echo hello | sha256sum Then I get the following result 5891b5b522d5df086d0ff0b110fbd9d21bb4fc7163af34d08286a2e846f6be03 - I notice there is dash at the end. But when I use Python hashlib or Java java.security.MessageDigest , they give me the same result as follows: 2cf24dba5fb0a30e26e83b2ac5b9e29e1b161e5c1fa7425e73043362938b9824 So, could anyone point out where I got it wrong please? Thanks. Python: >>> import hashlib >>> hashlib.sha256("hello").hexdigest() Java: MessageDigest md = MessageDigest.getInstance("SHA-256");

Docker的基本操作 Docker镜像 Docker获取镜像 从 Docker 镜像仓库获取镜像的命令是 docker pull 。其命令格式为 docker pull [选项] [Docker Registry 地址[:端口号]/]仓库名[:标签] Docker 镜像仓库地址:地址的格式一般是 <域名/IP>[:端口号] 。默认地址是 Docker Hub。 仓库名:如之前所说,这里的仓库名是两段式名称,即 <用户名>/<软件名> 。对于 Docker Hub,如果不给出用户名,则默认为 library ,也就是官方镜像。 比如 $ docker pull ubuntu:16.04 16.04: Pulling from library/ubuntu bf5d46315322: Pull complete 9f13e0ac480c: Pull complete e8988b5b3097: Pull complete 40af181810e7: Pull complete e6f7c7e5c03e: Pull complete Digest: sha256:147913621d9cdea08853f6ba9116c2e27a3ceffecf3b492983ae97c3d643fbbe Status: Downloaded newer image for ubuntu:16.04
