Hi Team,

I have .Net core console application which is running on linux platform.
I am using one .INI file for storing project specific information (like user name and password information etc.) While loading time, the application will parse the .INI file data and storing to memory class.

I need to secure my password information in .INI file. I don't want to use password in plaintext
How to handle it? Please help me on this.

Regards
Prabs

    Storing sensitive information such as a password is not wise as a savvy user can decompile your application and/or inspect data in memory.

    Example decompiling code with encryption methods.

    I am maintaining SNMP V3 parameters in INI file as plain text.

    .INI FILE :

    [SNMP V3]
    SNMP_VERSION=3
    UserName=UNAME
    AuthPassword=authpwd
    AuthProtocol=SHA512
    PrivPassword=privpasswd
    PrivProtocol=AES256

    I don't want to allow other users modify this information. How to handle this?
