Simple encryption and decryption algorithms, reversible and non-reversible data encryption: Algorithm 1: (not reversible) to ASCII table 32 ~ ~ 126 characters, encrypted, shown as 128 ~ ~ 255 characters. 128 ~ ~ 255 characters will people seem more headaches. . . . . . Security. When the ch [?] Even when the value is: ch [?] = 255-ch [?] Bits of the* 10-ch [?] 10 when the ch [?] Value is odd: ch [ ?] = 128+ ch [?] bit of a* 10+ ch [?] 10 when the ch [?] the value of prime number when: ch [?] = 128+ ch [?] the single-digit+ ch [ ?] of 10 Algorithm 2: (reversible) when ch [?] value can be divisible by 3 pm: ch [?]-= 2, otherwise, ch [?]-= 3
