The length of the code has an even number of characters, so looking at pairs of characters for a clue:

#% $& %) $* #$ $% #^ %) #^ %^

There are 10 groups, which could match a prefix/suffix pair with an unknown keyword. Assuming the first 5 pairs are the prefix and the last 5 are the suffix, we see that the positions where the numbers would be all have # as their first character.

[hint]

Convert the symbols to their QWERTY keyboard equivalent:

35 47 50 48 34 45 36 50 36 56

[/hint]

Taking the pairs as hexadecimal numbers, we get:

5GPH4E6P6V

With a missing keyword. Since we converted from symbols, symbols is a candidate for the keyword:

5GPH4SYMBOLSE6P6V

Code #2

Our thanks goes out to kon5000 for giving us “pointers” to the keyword.

Observations

Looking at the code and trying the standard methods does not reveal much, except that the . seems to be in the spot of a keyword.

[hint]Since there are no numbers in the code, try transforming the letters into something else.
[/hint]

Remove the . and convert to Morse .-.. --- .--- .-.. ...- .-.. -.-- .-. .-. --.. -... --- .-.. .-.. .--. -.--
Make groups of 6, ignoring the spaces between the morse .-..-- -.---. -..... -.-..- .--.-. .-.--. .-...- --.-.. .-...- -.-.--
Convert the code to Braille where - is a dot and . is blank and writing .-..--
123456
as
.. 14
-- 25
.- 36 Result should look like this 4 n a u 6 j 5 f 5 z

Converting from Braille Shorthand to text, we get 4nau6j5f5z
Here we have a prefix and suffix, now back to the keyword.

. can also be read as Point, and we know one subject this with Point in its name: Darsana Point^{[1][2][3]} 4nau6DARSANAj5f5z

Code #3

Observations

The letter distribution appears random but there is a disproportionate amount of repeated numbers.
