There is a very strange computer programming langauge call Forth is a structured, imperative, reflective, concatenative, extensible, stack-based computer programming language and programming environment.
Sample:
0 value ii 0 value jj
0 value KeyAddr 0 value KeyLen
create SArray 256 allot \ state array of 256 bytes
: KeyArray KeyLen mod KeyAddr ;
: get_byte + c@ ;
: set_byte + c! ;
: as_byte 255 and ;
: reset_ij 0 TO ii 0 TO jj ;
: i_update 1 + as_byte TO ii ;
: j_update ii SArray get_byte + as_byte TO jj ;
: swap_s_ij
jj SArray get_byte
ii SArray get_byte jj SArray set_byte
ii SArray set_byte
;
: rc4_init ( KeyAddr KeyLen -- )
256 min TO KeyLen TO KeyAddr
256 0 DO i i SArray set_byte LOOP
reset_ij
BEGIN
ii KeyArray get_byte jj + j_update
swap_s_ij
ii 255 < WHILE
ii i_update
REPEAT
reset_ij
;
: rc4_byte
ii i_update jj j_update
swap_s_ij
ii SArray get_byte jj SArray get_byte + as_byte SArray get_byte xor
;
