At the same time, the proposed nucleotide operations can be used to mimic any hash algorithm of its bitwise operations similar to bitwise operations specified in SHA-2. The proposed hash has the following features: (1) it can be applied to all data, such as text, video, and image; (2)...
Secure Hash Algorithm 2 224, 256, 384, and 512 bits initially this was part of nimPDF project, then I decided to release it separately example: var sha = initSHA[SHA256]() sha.update("test SHA256") let digest = sha.final() or: let digest = computeSHA256("test SHA256") conversion...
We present a new version of the Secure Hash Algorithm-2 (SHA-2) formed on artificial sequences of deoxyribonucleic acid (DNA). This article is the first attempt to present the implementation of SHA-2 using DNA data processing. We called the new version DNSHA-2. We present new operations ...
Secure hash algorithm;SHA Definition The SHA (Secure Hash Algorithm) Family currently designates a family of six different hash functions: SHA-0, SHA-1, SHA-224, SHA-256, SHA-384, and SHA-512 (National Institute of Standards and Technology (NIST)1995; National Institute of Standards and Tech...
安全哈希算法(Secure Hash Algorithm)主要适用于数字签名标准 (Digital Signature Standard DSS)里面定义的数字签名算法(Digital Signature Algorithm DSA)。对于长度小于2^64位的消息,SHA1会产生一个160位的消息摘要。当接收到消息的时候,这个消息摘要可以用来验证数据的完整性。在传输的过程中,数据很可能会发生变化,那么...
SHA(Secure Hash Algorithm)系列算法包括SHA-1、SHA-256、SHA-384、SHA-512等,它们被广泛应用于密码学领域。在安全性方面,SHA算法的主要考虑因素包括抗碰撞性(Preimage Resistance)、抗第二原像攻击(Second Preimage Resistance)和抗碰撞性(Collision Resistance)。
A definition of the term "Secure Hash Algorithm" (SHA) is presented. It refers to a group of related cryptographic hash functions. It is mentioned that the most utilized SHA family is SHA-1 which is used in different security applications and protocols, including transport layer security (TLS...
SHA 2, 512-bit digest Specifies the Secure Hash Algorithm SHA 2 with the 512-bit digest. null Indicates that AES-GCM or AES-GMAC is configured as the encryption algorithm. You must choose the null integrity algorithm if AES-GCM has been configured as the encryption algorithm. Ps...
