Tip to generate random password in Kotlin

gistfile1.txt

fun generateRandomPassword(): String {
    val chars = "0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ"
    var passWord = ""
    for (i in 0..31) {
        passWord += chars[Math.floor(Math.random() * chars.length).toInt()]
    }
    return passWord
}

// Could be this way for a length of 8 password with visible ascii characters
var password = List(8){(0x21..0x7e).random().toChar()}.joinToString("")
