Same process lang naman sya sa base32. Ang pinagkaiba nga lang, 6digits ang sa base64 at 5digits sa base32.
Example ang PT natin ay BERAT.

To encrypt:
Convert the B,E,R,A,T sa binary code
B- 01000010
E- 01000101
R- 01010010
A- 01000001
T- 01010100
COMBINE:
BERAT=> 01000010 01000101 01010010 01000001 01010100
DIVIDE IT BY 6DIGITS:
010000
100100
010101
010010
010000
010101
0100
JUST ADD ZERO (0) KUNG KULANG SYA.

LOCATE SA TAAS:

010010- S
010000- Q
010101- V
010000- Q
Ct: QkVSQVQ
To decrypt:
Locate mo lang ang CT sa taas then kunin ang value.
Combine 'em and divide it into 8digits and convert nyo na sya sa binary plaintext.
