Cipher Text

Cipher Text

The encrypted result is virtually useless to anyone who lacks the correct key. The length of the key, and the number and types of incorporated encryptions determines the cipher text’s capability to withstand unauthorized access. Ultimately, the security of a cryptosystem depends on the secrecy of one or more of the keys, rather than with the secrecy of the encryption algorithm. A strong cryptosystem has a large number of possible keys, making it time- and resource-consuming to try all possible keys (brute force). Brute force attacks, as depicted on television, where a computer generates potential keys, are typically more fantasy than reality.
