Abstract
In a process for the cryptographic processing of data in a cryptographic system, processing takes place in two parts. In the first part the data transmission routines within a data entity and a coded text entity are detected. The clear text and the cryptographic are separately processed cryptographically in the second part and then recombined in the first part with the data transmission routines.
