I understand the phrase "settle your hash" means to subdue someone through the use of threats or violence. For example, a heated argument between two individuals where insults were being lobbed to and fro might lead one to exclaim: If you keep disparaging my mother like that I am going to settle your hash.

What is hashish?
Hashish — also known as hash — is a drug made by compressing the parts of a cannabis plant that contains the highest levels of THC. Hash is traditionally associated with Middle Eastern and and Mediterranean cultures, but has been used globally for decades.
What is a hashing algorithm?
Hashes are the output of a hashing algorithm like MD5 (Message Digest 5) or SHA (Secure Hash Algorithm). These algorithms essentially aim to produce a unique, fixed-length string – the hash value, or “message digest” – for any given piece of data or “message”.
What is hashing and how does it work?
Hashing requires processing the data from a block through a mathematical function, which results in an output of a fixed length. Using a fixed-length output increases security since anyone trying to decrypt the hash won’t be able to tell how long or short the input is simply by looking at the length of the output.

These algorithms essentially aim to produce a unique, fixed-length string – the hash value, or “message digest” – for any given piece of data or “message”. As every file on a computer is, ultimately, just data that can be represented in binary ...
What is Hashing Used For?
Some legacy AV solutions rely entirely on hash values to determine if a file is malicious or not, without examining the file’s contents or behaviour. They do this by keeping an internal database of hash values belonging to known malware. On scanning a system, the AV engine calculates a hash value for each executable file on the user’s machine and tests to see if there is a match in its database.

Why is hashing important in computer security?
Hashes are a fundamental tool in computer security as they can reliably tell us when two files are identical, so long as we use secure hashing algorithms that avoid collisions. Even so, as we have seen above, two files can have the same behaviour and functionality without necessarily having the same hash, so relying on hash identity for AV detection is a flawed approach.
How to calculate hash value in Windows 10?
To calculate a file’s hash in Windows 10, use PowerShell’s built in Get-FileHash cmdlet and feed it the path to a file whose hash value you want to produce. By default, it will use the SHA-2 256 algorithm:
Why are hashes useful?
Despite that, hashes are still useful for security analysts for such things as sharing IOCs and threat-hunting, and you will undoubtedly encounter them on a daily basis if you work anywhere in the field of computer and network security.
Is threat hunting easier?
Threat hunting is also made easier thanks to hash values. Let’s take a look at an example of how an IT admin could search for threats across their fleet using hash values in the SentinelOne management console.

What is a hash?
A ‘hash’ was a mess (from French ‘hachée’) and by ‘settling’ it, one sorted it out. It is also possible to make a hash (or mess) of something.
What happens when you use hash?
Long-term, chronic use of hash leads to physical dependence. When someone is physically addicted to a substance, they experience withdrawal symptoms when they do not use it.
Why is hashing dangerous?
This effect is extremely dangerous when combined with alcohol because vomiting is the body’s natural way of eliminating dangerous levels of alcohol from the body. Alcohol intensifies the symptoms of hash use, which include hallucinations and anxiety.
What is hash oil?
However, you can use hash oil, also known as honey oil or cannabis oil, which is extracted from the cannabis plant. It contains many of its resins and terpenes, including tetrahydrocannabinol (THC), cannabidiol (CBD), and other cannabinoids.
How much THC is in hash?
Most strains of hash contain high levels of THC concentrations of about 40 to 60 percent or higher. One particularly potent type of hash has a 90 percent THC concentration.
Which is more potent, hash or thc?
Have different potencies. Hash has a higher concentration of THC and therefore, is more potent.
What are the health effects of drinking alcohol and hash?
Long-term mixing of alcohol and hash increases the risk of liver disease, kidney disease, immune system problems, cardiovascular issues, and gastrointestinal health problems.
What color is hash?
Hash comes in ball or block form. It varies in color and is usually green, red, black, or brown.

How Hashes Work
- Typical hash functions take inputs of variable lengths to return outputs of a fixed length. A cryptographic hash function combines the message-passing capabilities of hash functions with security properties. Hash functions are commonly used data structures in computing systems for tasks, such as checking the integrity of messages and authenticating information. While they ar…
Hashing and Cryptocurrencies
- The backbone of a cryptocurrency is the blockchain, which is a global ledger formed by linking together individual blocks of transaction data. The blockchain only contains validated transactions, which prevents fraudulent transactions and double spending of the currency. The resulting encrypted value is a series of numbers and letters that do not resemble the original data and is c…
Special Considerations
- Solving the hash requires the miner to determine which string to use as the nonce, which itself requires a significant amount of trial-and-error. This is because the nonce is a random string. It is highly unlikely that a miner will successfully come up with the correct nonce on the first try, meaning that the miner may potentially test a large number of nonce options before getting it rig…
An Example of A Hash
- Hashing the word “hello” will produce an output that is the same length as the hash for “I am going to the store.” The function used to generate the hash is deterministic, meaning that it will produce the same result each time the same input is used. It can generate a hashed input efficiently; it also makes determining the input difficult (leading to mining), as well as makes small changes to the i…
What Is A Hashing Algorithm?
How Hashes Establish Identity
- Hashes cannot be reversed, so simply knowing the result of a file’s hash from a hashing algorithm does not allow you to reconstruct the file’s contents. What it does allow you to do, however, is determine whether two files are identical or not without knowing anything about their contents. For this reason, the idea that the result is unique is fundamental to the whole concept of hashes. If t…
What Is Hashing Used for?
- Given a unique identifier for a file, we can use this information in a number of ways. Some legacy AV solutions rely entirely on hash values to determine if a file is malicious or not, without examining the file’s contents or behaviour. They do this by keeping an internal database of hash values belonging to known malware. On scanning a system, the AV engine calculates a hash va…
Benefits of Hashes in Threat Hunting
- Threat hunting is also made easier thanks to hash values. Let’s take a look at an example of how an IT admin could search for threats across their fleet using hash values in the SentinelOne management console. Hashes are really helpful when you identify a threat on one machine and want to query your entire network for existence of that file. Click the Visibility icon in the Sentinel…
