Access denied after setting user's password with SHA256 in phpMyAdmin

由 一曲冷凌霜 提交于 2020-01-03 06:05:08
问题 After seeing that default passwords generated by phpMyAdmin used mysql_native_password and therefore hashes didn't changed when equal passwords where used, I updated one user's password and set the hashing to SHA256. When I tried to login again using the setted password it says: mysqli_real_connect(): (HY000/1045): Access denied for user 'xxxx'@'xxxx' (using password: YES). The server uses https and phpMyAdmin forces to uses SSL as well. Once the password is changed with SHA256, the only way

Docker学习之镜像操作

由 大兔子大兔子 提交于 2020-01-01 12:57:06
使用Docker镜像 以下都是Docker镜像的一系列重要名操作，包括获取、查看、搜索、删除、创建、存出或载入、上传等。可使用docker image help命令查看帮助。 1.获取镜像(pull) 使用pull子命令下载镜像 格式为： docker [image] pull NAME[:TAG]，其中，NAME是镜像仓库名称，用以区分镜像， TAG是镜像的标签，往往用来表示版本信息，如果不显示指定TAG，则默认为latest标签，这会下载仓库中最新版本的镜像。 例如获取一个centos系统的基础镜像可以使用如下的命令： $ docker pull centos sudo docker pull centos Using default tag: latest latest: Pulling from library/centos a02a4930cb5d: Pull complete Digest: sha256:184e5f35598e333bfa7de10d8fb1cebb5ee4df5bc0f970bf2b1e7c7345136426 Status: Downloaded newer image for centos:latest 镜像文件一般由若干层（layer）组成，每一层都对应一个唯一的id（完整的id包括256比特，64个十六进制字符组成）

Docker三大核心概念之镜像

由 馋奶兔 提交于 2020-01-01 12:55:39
1.1 获取镜像 使用docker pull命令，从Docker Hub镜像源来下载镜像，该命令的格式为：docker pull NAME[:TAG]，其中NAME是仓库的名称，TGA是镜像的版本标签（往往是用来表示版本信息）通常情况下描述一个镜像需要包括“名称+标签”信息。 以下的命令用来获取一个Ubuntu 14.04的系统的基础镜像 # docker pull ubuntu:14.04 Trying to pull repository docker.io/library/ubuntu ... 14.04: Pulling from docker.io/library/ubuntu 8284e13a281d: Pull complete 26e1916a9297: Pull complete 4102fc66d4ab: Pull complete 1cf2b01777b2: Pull complete 7f7a2d5e04ed: Pull complete Digest: sha256:4851d1986c90c60f3b19009824c417c4a0426e9cf38ecfeb28598457cefe3f56 Status: Downloaded newer image for docker.io/ubuntu:14.04 如果 不指定标签 ，则默认会选择下载仓库中 最新

SHA256 in PHP & Java

由 流过昼夜 提交于 2020-01-01 07:08:08
问题 I'm porting some Java code to PHP code. In Java I have a hash SHA256 code as below: public static String hashSHA256(String input) throws NoSuchAlgorithmException { MessageDigest mDigest = MessageDigest.getInstance("SHA-256"); byte[] shaByteArr = mDigest.digest(input.getBytes(Charset.forName("UTF-8"))); StringBuilder hexStrBuilder = new StringBuilder(); for (int i = 0; i < shaByteArr.length; i++) { hexStrBuilder.append(Integer.toHexString(0xFF & shaByteArr[i])); } return hexStrBuilder.toString

How do I check if my SSL Certificate is SHA1 or SHA2 on the commandline

问题 How do I check if my SSL Certificate is using SHA1 or SHA2, from the commandline? And yes, i this is similar to this, but i need a cli-tool and i want to understand how it is done. 回答1: after googling for quite some time i came up with the following snippet (unix): openssl s_client -connect <host>:<port> < /dev/null 2>/dev/null | openssl x509 -text -in /dev/stdin | grep "Signature Algorithm" windows (thanx Nick Westgate, see below) certutil -dump cacert.pem | find "Algorithm" 回答2: I know the

pyspark generate row hash of specific columns and add it as a new column

由 六眼飞鱼酱① 提交于 2019-12-30 09:53:33
问题 I am working with spark 2.2.0 and pyspark2. I have created a DataFrame df and now trying to add a new column "rowhash" that is the sha2 hash of specific columns in the DataFrame. For example, say that df has the columns: (column1, column2, ..., column10) I require sha2((column2||column3||column4||...... column8), 256) in a new column "rowhash" . For now, I tried using below methods: 1) Used hash() function but since it gives an integer output it is of not much use 2) Tried using sha2()

SHA256 base 64 hash generation in SQL Server

由 依然范特西╮ 提交于 2019-12-30 07:09:09
问题 I need to generate a SHA256 base 64 hash from a table in SQL server but I can't find that algorithm in the list HASHBYTES arguments. Is there a way to generate it directly in SQL Server? Duplicate disclamer: My question is not duplicate of SHA256 in T-sql stored procedure as I am looking for the SHA256 base 64 version of the algorithm which is not listed in the page. Numeric Example I have this query result in SQL Server Start date,End date,POD,Amount,Currency 2016-01-01,2016-12-31,1234567890

SHA 256 Different Result

由 有些话、适合烂在心里 提交于 2019-12-30 02:10:27
问题 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
