WebA plaintext can be written in any language, including English and Java code. Before launching an attack, it's critical to understand the plaintext. There are 5 types of them, and all of them are given below: Known-Plaintext Analysis (KPA): The attacker is aware of plaintext-ciphertext pairings in this case. http://www.crypto-it.net/eng/attacks/known-plaintext.html

Some common attack models are: • Ciphertext-only attack (COA) - in this type of attack it is assumed that the cryptanalyst has access only to the ciphertext, and has no access to the plaintext. This type of attack is the most likely case encountered in real life cryptanalysis, but is the weakest attack because of the cryptanalyst's lack of information. Modern ciphers are required to be very resistant to this type of attack.
