WebThe four hash functions that comprise SHA-2 are SHA-224, SHA-256 (SHA 256 Algorithm), SHA-384, and SHA-512, with the numeric portion of the name indicating the number of bits in the key. SHA-2 functions are more secure than SHA-1 although not as widely used currently. WebFor example, MD2, MD4, MD5, SHA-0, SHA-1, Panama, HAVAL, Tiger, SipHash have been broken by hackers. Website shattered.io is one of the good examples of SHA1 collisions that shows how this weakness can use to fake digital signatures, demonstrated by two separate signed PDF documents and different content, but with the same hash value and ...

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. It was designed by the United States National Security Agency, and is a U.S. Federal Information … See more SHA-1 produces a message digest based on principles similar to those used by Ronald L. Rivest of MIT in the design of the MD2, MD4 and MD5 message digest algorithms, but generates a larger hash value (160 bits vs. … See more Example hashes These are examples of SHA-1 message digests in hexadecimal and in Base64 binary to ASCII text encoding. • SHA1("The … See more • Comparison of cryptographic hash functions • Hash function security summary • International Association for Cryptologic Research • Secure Hash Standard See more Cryptography SHA-1 forms part of several widely used security applications and protocols, including TLS and SSL, PGP, SSH, S/MIME, and See more For a hash function for which L is the number of bits in the message digest, finding a message that corresponds to a given message digest can always be done using a brute force … See more Below is a list of cryptography libraries that support SHA-1: • Botan • Bouncy Castle • cryptlib • Crypto++ • Libgcrypt See more 1. ^ Stevens, Marc (June 19, 2012).
