i have big string

approx 4000 characters

i want encrypt , decypt using md5 because of want convert in small string please me lot of finding found base64 not our solution please 1 me

my_string="abcdefghhhhhhhhhhhhhhhhhhhhhh"       base64.encode64(my_string)

it gives lengthy string.

encrypting string not make smaller, @ best same length. think looking way compress string. aside, md5 one-way hashing algorithm, means designed, there way of recovering source string (it turns out designed rather poorly).
