问题描述
亲爱的先生，
我在注册页面使用了md5加密，也用于登录加密密码并检查sql数据库，但问题是。
当我注册一个新帐户时，它会加密密码，例如
naveen123 = adkjfdaf35a6df54das65fa4dsda4f
但是当我使用相同的密码登录时，它会自动在最后添加两个字符串，例如
naveen123 = adkjfdaf35a6df54das65fa4dsda4f8c
我的工作怎么样？请建议
Dear Sir,
I have used md5 encryption in registration page and also used in login for encrypt password and check with sql database but problem is.
When i register a new account it encrypt the password like
naveen123 = adkjfdaf35a6df54das65fa4dsda4f
but when i login with the same password then it automatically adds two string extra at the end like
naveen123 = adkjfdaf35a6df54das65fa4dsda4f8c
what i do? please suggest
