Hi,

These 2 may help you for this

FIEB_PASSWORD_ENCRYPT

FIEB_PASSWORD_DECRYPT

In general all FMs related to Password Encryption are in this Function group - FIEB_PASSWORD

Hi,

May be this program willl give you some hint..

selection-screen begin of block block.

parameters: program(30) obligatory.

selection-screen begin of line.

selection-screen comment 1(8) pwd.

selection-screen position 35.

parameters: password(8) modif id aaa.

selection-screen end of line.

selection-screen end of block block.

*

data: message(60) type c.

*

at selection-screen output.

loop at screen.

if screen-group1 = 'AAA'.

screen-invisible = '1'.

modify screen.

endif.

endloop.

*

initialization.

pwd = 'Password'.

*

start-of-selection.

tables: trdir.

• User name and password check

if password <> 'ABCDEFG'.

write: / 'Wrong password'.

exit.

endif.

• SAP owned?

if not program cp 'Z' and not program cp 'Y'.

write: / 'Do not hide original SAP programs!'.

exit.

endif.

• Exists?

select single * from trdir where name = program.

if sy-subrc <> 0.

write: / 'Program does not exists!'.

exit.

endif.

• Does it have a current generated version?

data: f1 type d, f3 type d.

data: f2 type t, f4 type t.

EXEC SQL.

SELECT UDAT, UTIME, SDAT, STIME INTO :F1, :F2, :F3, :F4 FROM D010LINF

WHERE PROG = :PROGRAM

ENDEXEC.

if f1 < f3 or ( f1 = f3 and f2 < f4 ).

write: / 'The program has no recent generated version!'.

exit.

endif.

• Compose a new program name

data: new_name(30), i type i, j type i.

new_name = program.

do 30 times.

i = sy-index - 1.

new_name+i(1) = '_'.

• Search for acceptable program name variations

j = 0.

select * from trdir where name like new_name.

j = j + 1.

endselect.

if j = 1.

exit.

endif.

new_name = program.

enddo.

• Cannot generate appropriate program name

if j > 1.

write: / 'Cannot generate appropriate program name'.

exit.

endif.

• Check if it is already hidden

data: f5(30).

EXEC SQL.

SELECT PROG INTO :F5 FROM D010S WHERE PROG = :NEW_NAME

ENDEXEC.

if f5 is initial.

• There is no such hidden program, hide it

EXEC SQL.

UPDATE D010S SET PROG = :NEW_NAME WHERE PROG = :PROGRAM

ENDEXEC.

concatenate 'Program' :program 'was hidden.'

into message separated by space.

else.

• There is already a hidden program there, unhide it

EXEC SQL.

UPDATE D010S SET PROG = :PROGRAM WHERE PROG = :NEW_NAME

ENDEXEC.

concatenate 'Program' :program 'was restored.'

into message separated by space.

endif.

write message.

• end of program
