WebMay 29, 1997 · In cryptography, cipher text (ciphertext) is data that has been encrypted. Cipher text is unreadable until it has been converted into plain text ( decrypted) with a key. Webopedia Staff Since 1995, more than 100 tech experts and researchers have kept Webopedia’s definitions, articles, and study guides up to date. WebCryptanalysis refers to the study of ciphers, ciphertext , or cryptosystems (that is, to secret code systems) with a view to finding weaknesses in them that will permit retrieval of the plaintext from the ciphertext, without necessarily knowing the key or the algorithm . This is known as breaking the cipher, ciphertext, or cryptosystem.

WebCryptography is the study of secure communications techniques that allow only the sender and intended recipient of a message to view its contents. The term is derived from the Greek word kryptos, which means hidden. WebApr 12, 2024 · Classical cryptography relies on mathematical algorithms to encrypt and decrypt data. These algorithms use keys, which are secret pieces of information that determine how the data is transformed.

In cryptography, encryption is the process of encoding information. This process converts the original representation of the information, known as plaintext, into an alternative form known as ciphertext. Ideally, only authorized parties can decipher a ciphertext back to plaintext and access the original information. Encryption does not itself prevent interference but denies the intelligible conte… WebCryptography is the process of converting between readable text, called plaintext, and an unreadable form, called ciphertext. This occurs as follows: The sender converts the plaintext message to ciphertext. part of the process is called encryption(sometimes encipherment). The ciphertext is transmitted to the receiver.
