I use a solution to crypt a string that I found using OpenSSL. But the
crypted string becomes very long, too long for a varchar 255 to hold it.
What can I do to make it shorter? Or should I just use text as column in
the mysql db?

public_key_file = 'lib/public.pem'
public_key =  OpenSSL::PKey::RSA.new(File.read(public_key_file))
@encrypted_string = Base64.encode64(public_key.public_encrypt(string))
