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.
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 It was withdrawn shortly after publication due to an undisclosed "significant flaw" and replaced by the slightly revised version SHA-1.SHA-1 A 160-bit hash function which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 creates a 128-bit digest?
MD5
What is md5 protocol?
MD5 (like SHA-1 or CRC32) is a common message-digest algorithm for data integrity. MD5 is widely used as a cryptographic hash function producing a 128-bit (16-byte) hash value or checksum, typically expressed in text format as a 32 digit hexadecimal number (e.g. 90506d869e65e896d5a8474b00097610). This essentially is a way to digitally sign a block of text or media to prevent tampering or modification. A receiver can calculate the md5 hash value independently to verify the contents match the expected hash value. If a different hash value is computed then the content has been changed from the original. The newer SHA-1, SHA-256, and SHA-512 algorithms respectively generate a 160-bit, 256-bit, and 512-bit hash value for greater security.
What does MD5 encryption mean?
You are probably referring to the MD5 Message-Digest Algorithm which is a widely used cryptographic hash function that produces 128-bit (16-byte) hash values. A hash function is an algorithm that takes a block of data and creates a string of data (hash) of fixed length. By running the algorithm on a received block of data, a user should be able to detect whether the data has been altered because a given block of data should always yield the same hash unless it has been altered. Ideally a hash function will allow easy computation of the hash value for any given message but make it hard to start with the hash value and come up with a message that will yield that hash value. It should also be so difficult to modify a message without changing the hash that the time and effort necessary to do it exceeds the value of doing it and extremely difficult or impractical to find two different messages with the same hash. Note that by its nature the MD5 hash is not supposed to allow you to recover the message that was processed. Usually when we use the word "encryption" we are talking about a process where a message is converted to something called "cyphertext" which is unreadable unless you have the right algorithm and key to decrypt it and convert it back to the original message. In this respect it is more accurate to refer to "MD5 hashing" rather than MD5 encryption. See the attached link for more details on the MD5 hash.
What data type is suitable for password field?
We never store passwords in a password field. If we did that, anyone with access to the database would have access to all the passwords. Instead, we store the output from a one-way cryptographic hashing function. That is, when a user creates a password, we store the hash value generated from that password via the hashing function. When the user subsequently enters their password in order to log on, the hash value generated by the entered password is compared with the stored hash value. If the two hash values match exactly then the correct password was entered. Being one-way, it is not possible to determine the password from the hash value, even if we know the precise implementation details of the hash function employed to create the hash value. This is the safest way to store passwords; we simply need to ensure that the same hash function that was used to generate the hash is also used to validate the user's password at logon. Cryptographic hashes can vary in length depending on which function was used to generate the hash value. Typical values are 128-bit, 160-bit, 256-bit and 512-bit, thus a fixed-length binary field of the required length would be suitable for storing the hash values.

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
Why is it called a hash tag?
Because the word bit is a "tag" and the symbol at the start "#" is called a "hash".
How does an md5 hash work specifically?
In cryptography, MD5 (Message-Digest algorithm 5) is a widely used, partially insecure cryptographic hash function with a 128-bit hash value. As an Internet standard (RFC 1321), MD5 has been employed in a wide variety of security applications, and is also commonly used to check the integrity of files. An MD5 hash is typically expressed 32-character string of hexadecimal numbers.The MD5 hash also known as checksum for a file is a 128-bit value, something like a fingerprint of the file. There is a very small possibility of getting two identical hashes of two different files. This feature can be useful both for comparing the files and their integrity control. Let us imagine a situation that will help to understand how the MD5 hash works. Alice and Bob have two similar huge files. How do we know that they are different without sending them to each other? We simply have to calculate the MD5 hashes of these files and compare them.The MD5 hash is used in many websites.
