# How to Obtain the Encrypted Key and Password Ciphertext for Authorization and Authentication

Sermant supports using keys and encrypted passwords for authorization and authentication in dynamic configuration scenarios. Below are the methods to obtain the encrypted key and password ciphertext:

# Supported Versions and Limitations

To obtain the encrypted key and ciphertext, you need a runtime environment with JDK 1.8 or above:

HuaweiJDK 1.8 (opens new window) / OpenJDK 1.8 (opens new window) / OracleJDK 1.8 (opens new window)

# Procedure

# 1. Preparation

Download the script (opens new window)

# 2. Generate the Key and Encrypted Password Ciphertext

Execute the script with the following command, and input your password when prompted:

java AesUtil
please input your password
123456
encryption key is T4bUktLn5P01Qs6unSuG5ZZElN05WUDAXOjaJgMB5eM=
encrypted password is u/K+lx/m9w1EpEjkM9R48s8PiVDHEpCUGz+1jWOasyzRrQ==

After entering your password, the script will output the encryption key T4bUktLn5P01Qs6unSuG5ZZElN05WUDAXOjaJgMB5eM= and the encrypted password u/K+lx/m9w1EpEjkM9R48s8PiVDHEpCUGz+1jWOasyzRrQ==.
