Twofish is a block cipher by Counterpane Labs, published in 1998. It was one of the five Advanced Encryption Standard (AES) finalists, and was not selected as AES. Twofish has a 128-bit block size, a key size ranging from 128 to 256 bits, and is optimized for 32-bit CPUs. Currently there is no successful cryptanalysis of Twofish. https://www.schneier.com/academic/twofish/ This animation is designed by Abdullah AlQahtani [email protected]

https://8gwifi.org/CipherFunctions.jsp Reference book: http://leanpub.com/crypto Cryptographic Algorithms generally fall into one of two different categories, or are a combination of both. Symmetric Fast Only provide confidentiality Examples: DES, AES, Blowfish, RC4, RC5 Asymmetric Large mathematical operations make it slower than symmetric algorithms No need for out of band key distribution (public keys are public!) Scales better since only a single key pair needed per individual Can provide authentication and nonrepudiation Examples: RSA, El Gamal, ECC, Diffie-Hellman problem with symmetric key cryptography DES (Data Encryption Standard) 64 bit key that is effectively 56 bits in strength Actual algorithm is called DEA (Data Encryption Algorithm) DES Modes Electronic Code Book Cipher Block Chaining (most commonly used for general purpose encryption) Cipher Feedback Output Feedback Counter Mode (used in IPSec) 3DES 112-bit effective key length Uses either 2 or 3 different smaller keys in one of several modes Modes EEE2/3 EDE2/3 AES NIST replaced DES in 1997 with this Uses the Rijndael algorithm Supports key/block sizes of 128, 192, and 256 bits Uses 10/12/14 rounds as block size increases IDEA (International Data Encryption Algorithm) Operates on 64 bit blocks in 8 rounds with 128 bit key Considered stronger than DES and is used in PGP Blowfish 64 bit block cipher with up to 448 bit key and 16 rounds Designed by Bruce Schneier RC4 Stream cipher with variable key size created by Ron Rivest RC5 Another Rivest cipher Block cipher with 32/64/128 bit blocks and keys up to 2048 bits RC6 Beefier version of RC5 submitted as AES candidate CAST 64 bit block cipher with keys between 40-128 bits with 12-16 rounds depending on key length CAST-256 used 128-bit blocks and keys from 128-256 bits using 48 rounds SAFER (Secure and Fast Encryption Routine) Set of patent-free algorithms in 64 and 128 bit block variants Variation used in Bluetooth Twofish Adapted version of Blowfish with 128 bit blocks, 128-256 bit keys and 16 rounds AES Finalist Kryptografie mit symmetrischem Schlüssel symmetric key cryptography symmetric key cryptography tutorial symmetric key cryptography example symmetric key cryptography vs asymmetric key cryptography symmetric and asymmetric key cryptography symmetric key cryptography Kryptografie mit symmetrischem Schlüssel Kryptographie mit symmetrischem Schlüssel Kryptographie mit symmetrischem Schlüssel Kryptografie mit symmetrischem Schlüssel und asymmetrische Schlüsselkryptographie symmetrische und asymmetrische Schlüsselkryptographie Kryptografie mit symmetrischem Schlüssel

What is CRYPTOGRAPHIC ACCELERATOR? What does CRYPTOGRAPHIC ACCELERATOR mean? CRYPTOGRAPHIC ACCELERATOR meaning - CRYPTOGRAPHIC ACCELERATOR definition - CRYPTOGRAPHIC ACCELERATOR explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. In computing, a cryptographic accelerator is a co-processor designed specifically to perform computationally intensive cryptographic operations, doing so far more efficiently than the general-purpose CPU. Because many servers' system load consists mostly of cryptographic operations, this can greatly increase performance. Intel's AES-NI is by far the most common cryptographic accelerator in commodity hardware. VIA PadLock is another recent example. Several operating systems provide some support for cryptographic hardware. The BSD family of systems has the OpenBSD Cryptographic Framework (OCF), Linux systems have the Crypto API, Solaris OS has the Solaris Cryptographic Framework (SCF) and Microsoft Windows has the Microsoft CryptoAPI. Some cryptographic accelerators offer new machine instructions and can therefore be used directly by programs. Libraries such as OpenSSL and LibreSSL support some such cryptographic accelerators. Almost all Unix-like operating systems use OpenSSL or the fork LibreSSL as their cryptography library. These libraries use cryptographic accelerators such as AES-NI if available.

What is SIGNCRYPTION? What does SIGNCRYPTION mean? SIGNCRYPTION meaning - SIGNCRYPTION pronunciation - SIGNCRYPTION definition - SIGNCRYPTION explanation - How to pronounce SIGNCRYPTION? Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ In cryptography, signcryption is a public-key primitive that simultaneously performs the functions of both digital signature and encryption. Encryption and digital signature are two fundamental cryptographic tools that can guarantee the confidentiality, integrity, and non-repudiation. Until 1997, they were viewed as important but distinct building blocks of various cryptographic systems. In public key schemes, a traditional method is to digitally sign a message then followed by an encryption (signature-then-encryption) that can have two problems: Low efficiency and high cost of such summation, and the case that any arbitrary scheme cannot guarantee security. Signcryption is a relatively new cryptographic technique that is supposed to perform the functions of digital signature and encryption in a single logical step and can effectively decrease the computational costs and communication overheads in comparison with the traditional signature-then-encryption schemes. Signcryption provides the properties of both digital signatures and encryption schemes in a way that is more efficient than signing and encrypting separately. This means that at least some aspect of its efficiency (for example the computation time) is better than any hybrid of digital signature and encryption schemes, under a particular model of security. Note that sometimes hybrid encryption can be employed instead of simple encryption, and a single session-key reused for several encryptions to achieve better overall efficiency across many signature-encryptions than a signcryption scheme but the session-key reuse causes the system to lose security under even the relatively weak CPA model. This is the reason why a random session key is used for each message in a hybrid encryption scheme but for a given level of security (i.e., a given model, say CPA), a signcryption scheme should be more efficient than any simple signature-hybrid encryption combination.
