Four common attack types for cryptanalysis.

Attack typesAvailable resource

Ciphertext-only attackThe attacker only knows the ciphertext
Known-plaintext attackThe attacker knows any given plaintext and also knows the corresponding ciphertext
Chosen-plaintext attackThe attacker can obtain access to the encryption machinery, choose the plaintext that would be useful for deciphering, and also know the corresponding ciphertext
Chosen-ciphertext attackThe attacker can obtain access to the decryption machinery, choose the ciphertext that would be useful for deciphering, and also know the corresponding plaintext
