sorry, that was a little bit to fast
now it works
function TSNMPRec.Pass2Key(const Value: AnsiString): AnsiString;
var
key: AnsiString;
begin
case FAuthMode of
AuthMD5:
begin
if FAuthPassKey = '' then
begin
key := MD5LongHash(Value, 1048576);
FAuthPassKey := key;
end
else
key := FAuthPassKey;
Result := MD5(key + FAuthEngineID + key);
end;
AuthSHA1:
begin
if FAuthPassKey = '' then
begin
key := SHA1LongHash(Value, 1048576);
FAuthPassKey := key;
end
else
key := FAuthPassKey;
Result := SHA1(key + FAuthEngineID + key);
end;
else
Result := '';
end;
end;
greetings
