Using function module MD5_CALCULATE_HASH_FOR_CHAR for cyrillic characters

Hey SAPlers!

I recently tried to use the function module 'MD5_CALCULATE_HASH_FOR_CHAR' for cyrillic characters, but unfortunately noticed that different strings produce the same hash. Is this because the codepage is different? If so, how can I still use cyrillic characters?

See the sample code below.

REPORT Z_TEST_HASH.


DATA: string1 TYPE string VALUE 'CUS&ДЕКЛT9',
      string2 TYPE string VALUE 'CUS&КОРРT9',
      hash1(32) TYPE c,
      hash2(32) TYPE c.


CALL FUNCTION 'MD5_CALCULATE_HASH_FOR_CHAR'
    EXPORTING
      data           = string1
    IMPORTING
      hash           = hash1
    EXCEPTIONS
      no_data        = 1
      internal_error = 2
      OTHERS         = 3.

CALL FUNCTION 'MD5_CALCULATE_HASH_FOR_CHAR'
    EXPORTING
      data           = string2
    IMPORTING
      hash           = hash2
    EXCEPTIONS
      no_data        = 1
      internal_error = 2
      OTHERS         = 3.

BREAK-POINT.

Hi Fredrik,
Have you tried class CL_ABAP_MESSAGE_DIGEST?

FM MD5_CALCULATE_HASH_FOR_CHAR has status "Not Released", so it should not be used (SAP Note 109533).

Regards,

Cris
