Exempel på hur man kan använda CRYPTOGRAPHY i en mening

• In cryptography, a block cipher is a deterministic algorithm that operates on fixed-length groups of bits, called blocks.
• In cryptography, a cipher (or cypher) is an algorithm for performing encryption or decryption—a series of well-defined steps that can be followed as a procedure.
• The fields of cryptography and computer security involve studying the means for secure communication and preventing security vulnerabilities.
• In cryptography, key size or key length refers to the number of bits in a key used by a cryptographic algorithm (such as a cipher).
• DH is one of the earliest practical examples of public key exchange implemented within the field of cryptography.
• Although its short key length of 56 bits makes it too insecure for modern applications, it has been highly influential in the advancement of cryptography.
• Elliptic-curve cryptography (ECC) is an approach to public-key cryptography based on the algebraic structure of elliptic curves over finite fields.
• For semigroups for which additive notation is commonly used, like elliptic curves used in cryptography, this method is also referred to as double-and-add.
• In cryptography, encryption is the process of transforming (more specifically, encoding) information in a way that, ideally, only authorized parties can decode.
• In cryptography, the International Data Encryption Algorithm (IDEA), originally called Improved Proposed Encryption Standard (IPES), is a symmetric-key block cipher designed by James Massey of ETH Zurich and Xuejia Lai and was first described in 1991.
• Kerberos builds on symmetric-key cryptography and requires a trusted third party, and optionally may use public-key cryptography during certain phases of authentication.
• In cryptography, an HMAC (sometimes expanded as either keyed-hash message authentication code or hash-based message authentication code) is a specific type of message authentication code (MAC) involving a cryptographic hash function and a secret cryptographic key.
• All mathematical aspects of computer science, including computational complexity theory, logic of programming languages, analysis of algorithms, cryptography, computer vision, pattern recognition, information processing and modelling of intelligence.
• In cryptography, the one-time pad (OTP) is an encryption technique that cannot be cracked, but requires the use of a single-use pre-shared key that is larger than or equal to the size of the message being sent.
• Public-key cryptography, or asymmetric cryptography, is the field of cryptographic systems that use pairs of related keys.
• In cryptography, RC4 (Rivest Cipher 4, also known as ARC4 or ARCFOUR, meaning Alleged RC4, see below) is a stream cipher.
• He is one of the inventors of public-key cryptography, the inventor of cryptographic hashing, and more recently a researcher and speaker on cryonics.
• In cryptography, SHA-1 (Secure Hash Algorithm 1) is a hash function which takes an input and produces a 160-bit (20-byte) hash value known as a message digest – typically rendered as 40 hexadecimal digits.
• The first recorded use of the term was in 1499 by Johannes Trithemius in his Steganographia, a treatise on cryptography and steganography, disguised as a book on magic.
• Originally covering subjects related to phreaking, anarchy and cracking, its articles also cover a wide range of topics including computer and physical security, hacking, cryptography, counter culture and international news.
