Which common hash algorithm is a 160 bit hash value?
Both SHA-1 and SHA-0 use a 160-bit hash value. Note that "SHA-0" is a retronym for the original SHA hash algorithm. SHA-1 corrected some significant flaws in the original algorithm that yielded some serious security weakness. The TIGER hash algorithm is designed to use a 192-bit hash, but also has the capability to use 160-bit and 128-bit hash values. The HAVAL algorithm can produce hashes in lengths of 128 bits, 160 bits, 192 bits, 224 bits, and 256 bits. One version of the RIPEMD algorithm, RIPEMD-160, has a 160-bit hash. Other versions of RIPEMD, RIPEMD-128, RIPEMD-256, and RIPEMD-320, use 128, 256, and 320-bit hashes respectively. Of these, the most common is probably SHA-1, which is available on most Windows based machines.
Which hash algorithm is commonly used in networking protocols and systems?
SHA-1
Which two algorithm are used for hash encoding to guarantee the ingerity of data?
MD5 and SHA
What is SHA in Unix?
SHA is cryptographic hash function used to encrypt passwords. The SHA hashing algorithm is not restricted to Unix, though. It is typically used to verify the integrity of some downloaded file, to make sure there was no corruption during transmission. Your Windows or OSX software may use this same algorithm without you knowing it.

What are Bit-coin and Ethereum mining algorithms?
Bit-coin uses the SHA-256 mining algorithm, while Ethereum used the Ethash mining algorithm until September, 2022, when it transitioned to a proof-of-stake consensus mechanism. SHA-256 is a crypt-ographic hash function that is designed to be resistant to collision attacks. This means that it is very difficult to find two different inputs that produce the same output hash. SHA-256 is also very efficient to compute, which makes it suitable for mining crypt-ocurrency. Ethash is a memory-hard mining algorithm that is designed to be resistant to ASIC miners. This means that it is more difficult to mine Ethereum using specialized hardware, which makes it more accessible to small-scale miners. Ethash is also more energy-efficient than SHA-256, which is one of the reasons why Ethereum was able to transition to a proof-of-stake consensus mechanism. Here is a brief overview of how each mining algorithm works: SHA-256 Miners take the header of a block and hash it using the SHA-256 algorithm. The miner then adjusts a value called the nonce until the hash is below a certain target difficulty. Once the miner finds a nonce that produces a valid hash, they can submit the block to the network. Ethash Miners create a large data structure called a DAG (Directed Acyclic Graph). The DAG is used to generate a random dataset, which is then used to compute a hash. Miners then compete to find a nonce that produces a valid hash. Once a miner finds a valid hash, they can submit the block to the network. You can find both algorithm asics on Asic Marketplace
What hash algorithm uses 160 bits?
SHA-0A retronym applied to the original version of the 160-bit hash function published in 1993 under the name "SHA". It was withdrawn shortly after publication due to an undisclosed "significant flaw" and replaced by the slightly revised version SHA-1.SHA-1 A 160-bit hash function which resembles the earlier MD5 algorithm. This was designed by the National Security Agency (NSA) to be part of the Digital Signature Algorithm.RIPEMMD-160Race Integrity Primitives Evaluation Message Digest is a 160-bit message digest hash algorithm developed in Belgium by Dobbertin, Bosselaers, and Preneel at the COSIC research group at the Katholieke Univeriteit Leuven, and first published in 1996. It is an improved version of RIPEMD, which in turn was based upon the design principles used in MD4, and is similar in performance to the more popular SHA-1.Tiger-160Tiger is a hash function designed by Anderson and Biham in 1995 for efficiency on 64-bit platforms. The size of a Tiger hash value is 192 bits. Truncated versions (known as Tiger/128 and Tiger/160) can be used for compatibility with protocols assuming a particular hash size.
Which hash algorithm is a 160 bit hash value?
Some well-known hash algorithms with a 160-bit output:RIPEMMD-160SHA-0/SHA-1Tiger-160
How many bit keys do need for a strong encryption?
It depends on the cipher you're using. For AES, the minimum is 128-bit (or 16-bytes) where as the maximum is 256 or 512 (depends on the implementation you're using - AES or Rijndael [from which AES was selected to become the AES standard by the US government]). Another thing to consider is the block-chaining mode and the hashing algorithm. It's generally recognized that ECB and SHA-1 are no longer secure (but still okay for using as a RNG), while SHA-256 hashes and debatably CBC and XTS.
What hash algorithm is used for password authentication?
In web development (most commonly PHP/MySQL), the two most common hashes are SHA-1 and MD5. Windows application developers have access to a wider array of hashes, including SHA-1, MD5, SHA356, and more.
