ABAP 加密解密程序

用于对字符串的加密和解密：

DATA: o_encryptor TYPE REF TO cl_hard_wired_encryptor, o_cx_encrypt_error TYPE REF TO cx_encrypt_error. DATA: v_ac_string TYPE string VALUE 'RICK', v_ac_xstring TYPE xstring, v_en_string TYPE string, v_en_xstring TYPE xstring, v_de_string TYPE string, v_de_xstring TYPE string, v_error_msg TYPE string.
