encrypt & decrypt strings

(1/2) > >>

Schranz0r:
This gbal encrypt and decrypt a string with a char like "x".
More math inside that functions!

Example:

--- Code: (glbasic) ---Code$ = "test"

encrypt_code$ = encrypt$(Code$,"x")

decrypt_code$ = decrypt$(encrypt_code$,"x")

WHILE TRUE

PRINT  encrypt_code$,10,10 // test decryped are: 33408-29088-33120-33408
PRINT  decrypt_code$,10,20

SHOWSCREEN
WEND
END
--- End code ---

You can de/encrypt levelpasswords, variables (integer/floats/strings), etc... 

"HOWTO": de/encrypt integer/float variables


--- Code: (glbasic) ---// set variable
my_var = 123

// set variable as string
Code$ = ""+my_var

// encrypt string
encrypt_code$ = encrypt$(Code$,"x")

// decrypt string
decrypt_code$ = decrypt$(encrypt_code$,"x")

// set decrypted string to integer
decrypt_var = decrypt_code$  // Thats GLBasic style :D


WHILE TRUE

// see the results
PRINT  encrypt_code$,10,10
PRINT  decrypt_var,10,30

SHOWSCREEN
WEND
END
--- End code ---

Thats it ;)

Kitty Hello:
why do floats crash? You're crypting a string, don't you?
Is it GP2X safe?

Whoops, floats are ok   :whistle:



--- Code: (glbasic) ---// set variable
my_var = 1876.08

// set variable as String
Code$ = ""+my_var

// encrypt string
encrypt_code$ = encrypt$(Code$,"x")

// decrypt string
decrypt_code$ = decrypt$(encrypt_code$,"x")

// set decrypted string to integer/float
decrypt_var = decrypt_code$


WHILE TRUE

// see the results
PRINT  encrypt_code$,10,10
PRINT  decrypt_var,10,30

SHOWSCREEN
WEND
END

--- End code ---

Yes, its GP2X safe :)

Moru:
Since I can't see how it's done, I can't use it... no use encoding something if I can't decode it on the other side, now is there? :-)

Kitty Hello:
There is encrpy _and_ decrypt functions, no?
