@echo off set "psCommand=powershell -Command "$pword = read-host 'Enter Password' -AsSecureString ; ^     $BSTR=[System.Runtime.InteropServices.Marshal]::SecureStringToBSTR($pword); ^         [System.Runtime.InteropServices.Marshal]::PtrToStringAuto($BSTR)"" for /f "usebackq delims=" %%p in (`%psCommand%`) do set password=%%p echo %password% This trick reads a password on Windows without echoing it to the screen by calling PowerShell from a batch file and using a SecureString prompt, so the typed characters do not appear in the console. Masking input is a small but useful courtesy in scripts that ask for credentials. Note that hiding the characters guards against shoulder surfing, not against the value being readable once it is in memory.

TRING is a windows software to generate True Random Numbers. It is based on Liner Congruential Model. This pseudo random number generator takes 4 inputs A,B,X,M from user to be used for the modified algorithm based on LCG approach. This generator is not meant to generate cryptographically secure random numbers i.e. if the values of A,B,X,M is available a crypt-analyst might crack the algorithm to predict the output over a time period. But that does not mean it is worthless. It can be used extensively for generating seed values to other pseudo-random number generators or true random number generators. Values obtained from it can be used for scientific research applications. Step 1: Run TRING.exe. Step 2: Insert values for A,B,X,M. A,B - values for multiplication and addition X - initial seed value M - modulo
