Cryptography is the science of secret writing or simply the conversion of data into a secret code for transmission over a public network. The original text, or "plaintext," is converted into a coded equivalent called "ciphertext" via an encryption algorithm. The ciphertext is decoded (decrypted) at the receiving end and turned back into plaintext. You can decode messages so that no one can read them but the person you choose. check this cool page: http://idecrypt.c
