Converting base 16 value to base 62 using Jmeter script

I want to convert base 16 value to base 62 value and this value to be used in jmeter script execution.

• UID_Hex = C8ED6D6046D34807BC5F0EBF065072EC
• TO Converted Value = 678y8VC5aSunoh06J8BhOe

I have a scenario where I have to fetch UID_Hex from DB and convert it into base 62 value and use it in further script execution.

How to convert base 16 to base 62 value?

You can do it using a suitable JSR223 Test Element and Groovy language

Example code:

static def base16ToBase10(String base16) {
    def result = new BigInteger('0')
    def chars = "0123456789ABCDEF"

    base16.each { c ->
        result = result * 16 + chars.indexOf(c.toUpperCase())
    }

    result
}

static def base10ToBase62(BigInteger base10) {
    def chars = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz"
    def result = ''

    while (base10 > 0) {
        def remainder = base10.mod(62)
        result = chars[remainder.intValue()] + result
        base10 = base10.divide(62 as BigInteger)
    }

    result
}

def UID_Hex = 'C8ED6D6046D34807BC5F0EBF065072EC'


def TO_Converted_Value = base10ToBase62(base16ToBase10(UID_Hex))

//do what you need with the converted value here
