README.md

The standard class CL_ABAP_MESSAGE_DIGEST can generate hashes for string or raw data.

This sample builds a hash from a single input character value.

DATA lo_digest TYPE Ref To cl_abap_message_digest.

DATA lv_timestamp TYPE timestampl.

DATA lv_hash_string TYPE string.
DATA lv_hash_base64 TYPE string.
