the science which studies methods to discovering the secret meaning of encrypted messages for which one does not possess the secret decoding information (called the key).

the methods and procedures used to discover the secret meaning hidden in encrypted messages.

involves the solution of a cryptogram without a key or any knowledge of the system used. This procedure is sometimes called codebreaking, even when the message is written in ciphers.

The conversion of encrypted messages into plain text without having the initial knowledge of the key used in encryption.

The process of breaking or cracking a code.

The science of deducing the plaintext from a ciphertext, without knowledge of the key.

Operations performed in converting encrypted messages to plain text without initial knowledge of the crypto-algorithm and/or key employed in the encryption.

the science of analyzing and deciphering codes and ciphers and cryptograms

Process of trying to recover crypto keys or plaintext associated with a crypto system.

The analysis of ciphers for the purpose of evaluating their security, usually by attempting to break them.

The analysis of an encryption system to determine or exploit its weaknesses

The mathematical science that deals with analysis of a cryptographic system in order to gain knowledge needed to break or circumvent the protection that the system is designed to provide. In other words, convert the cipher text to plaintext without knowing the key.

(crypt a nal y sis) - The part of cryptology that deals with studying a secret message or a group of secret messages and breaking the system so you can read what it says without first knowing the key.

Branch of the science that studies the techniques by which one can neutralize or break cryptographic algorithms. In particular, it is applied to the obtaining of plain texts from the interception of ciphered texts.

The art or science of transferring cipher text into plain text without initial knowledge of the key used to encrypt the plain text.

The testing of cryptography. An algorithm or program is said to have been cryptanalyzed if cryptographers have tested it for vulnerabilities.

the analysis of ciphertext in an attempt to determine the cleartext.

the study of cracking or breaking cryptographic systems

the art of breaking cryptosystems (from the Greek kryptós and analýein, "to loosen" or "to untie"). It is the science (and art) of recovering information from ciphers without knowledge of the secret key.

the art of breaking cryptosystems. The process of looking for errors or weaknesses in the implementation of an algorithm or of the algorithm itself.

To solve or "break'' a cryptosystem.

The science of breaking cryptographic algorithms.

The mathematics of the analysis of a cryptographic system. This is done to gain the knowledge to break or circumvent it and decrypt the associated ciphertext.

The study of methods of reading enciphered and encoded messages without original knowledge of the cipher method used or the current keys.

The art and science of breaking ciphertext.

The study of how to reconstitute, or DECRYPT, a secret message between a sender and receiver.

The study of methods for obtaining the meaning of encrypted information without access to the appropriate encryption key. In non-technical language, cryptanalysis is the practice of breaking or cracking an encryption code. Considered the opposite of cryptography. See also: cryptography, encryption key

The art and science of transferring ciphertext into plaintext without initial knowledge of the key used to encrypt the plaintext.

The reverse of cryptography, cryptanalysis is the art and science of breaking ciphers, ciphertexts, or keys.

The branch of cryptology dealing with the breaking of a cipher to recover information, or forging encrypted information what will be accepted as authentic.

The art and science of breaking encryption or any form of cryptography. See attack.

Study of how to defeat (compromise) cryptographic mechanisms. See also: 'Cryptography' and 'Cryptology' below...

Cryptanalysis (from the Greek kryptÃ³s, "hidden", and analÃ½ein, "to loosen" or "to untie") is the study of methods for obtaining the meaning of encrypted information, without access to the secret information which is normally required to do so. Typically, this involves finding the secret key. In non-technical language, this is the practice of codebreaking or cracking the code, although these phrases also have a specialised technical meaning (see code).
