Couldn't get your question correctly. Old methods of encryption (during the worldwars or may be even 70s,80s) are not much automated unlike the modern ones where you achieve encryption of bulk amount of data quickly. The problem with the modern ones is the computational cost factor. Modern ciphers at a higher security level require a few more years for a break whereas old ones like DES are already broken.
