The Whirlpool hash function is a Merkle–Damgård construction based on an AES -like block cipher W in Miyaguchi–Preneel mode. [2] The block cipher W consists of an 8×8 state matrix of bytes, for a total of 512 bits. The encryption process consists of updating the state with four round functions over 10 rounds.
PBKDF2 applies a pseudorandom function, such as hash-based message authentication code (HMAC), to the input password or passphrase along with a salt value and repeats the process many times to produce a derived key, which can then be used as a cryptographic key in subsequent operations. The added computational work makes password cracking much ...
Key checksum value. In cryptography, a Key Checksum Value (KCV) is the checksum of a cryptographic key. [1] It is used to validate the integrity of the key or compare keys without knowing their actual values. The KCV is computed by encrypting a block of bytes, each with value '00' or '01', with the cryptographic key and retaining the first 6 ...
NTRUEncrypt. The NTRUEncrypt public key cryptosystem, also known as the NTRU encryption algorithm, is an NTRU lattice-based alternative to RSA and elliptic curve cryptography (ECC) and is based on the shortest vector problem in a lattice (which is not known to be breakable using quantum computers). It relies on the presumed difficulty of ...
Secure multi-party computation (also known as secure computation, multi-party computation (MPC) or privacy-preserving computation) is a subfield of cryptography with the goal of creating methods for parties to jointly compute a function over their inputs while keeping those inputs private. Unlike traditional cryptographic tasks, where ...
AES-JS – portable JavaScript implementation of AES ECB and CTR modes. Forge – JavaScript implementations of AES in CBC, CTR, OFB, CFB, and GCM modes. asmCrypto – JavaScript implementation of popular cryptographic utilities with focus on performance. Supports CBC, CFB, CCM modes. pidCrypt – open source JavaScript library.
CTR_DBRG typically uses Advanced Encryption Standard (AES). AES-CTR_DRBG is often used as a random number generator in systems that use AES encryption. [9] [10] The NIST CTR_DRBG scheme erases the key after the requested randomness is output by running additional cycles. This is wasteful from a performance perspective, but does not immediately ...
Authenticated Encryption (AE) is an encryption scheme which simultaneously assures the data confidentiality (also known as privacy: the encrypted message is impossible to understand without the knowledge of a secret key [1]) and authenticity (in other words, it is unforgeable: [2] the encrypted message includes an authentication tag that the sender can calculate only while possessing the ...
