Hi leannonn,

usually it is not possible, unless you are talking about really simple cryptography algorithms, such as rotation-, simple-hash and XOR-ciphers. Otherwise, ciphered text should resemble, as much as possible, "white noise" (random text), and be also immune to frequency analysis.

Cheers!
