Got it to work!!!

encoding issue was below that I found searching

For this you want to use Base64 from the standard library. First use hex2bytes to convert your string to a byte array, then base64encode to convert it back to a string:  
using Base64  
function base16to64(st::AbstractString)  
bytes = hex2bytes(st)  
return base64encode(bytes)  
end
