What is the difference between 'Function' and 'role'?
Something's function is what its used for. Example: Your thumb's function is to allow you to grip things with your hand. Somethings role is its purpose. Example: Your thumb is an evolutionary trait due to the need to survive, it's role is to let humans and primates get one step ahead of the other animals on the Earth due to the need to survive and carry on the species. ------------------------------------------- Think as the "Function" as an action; something that is used, or that you will utilize to 'do' something; eg. complete a manuever or task. And think of "role" as to what is being achieved; the contribution for the desired 'act' or function. function: how something can be used/is used; its value or significance -- as to -- role: what something does/is doing; in contribution thereof/ the obligations, duty, or purpose for the overall achievement Example: A USB connection cable for your Android phone functions as the communication transport link for data transfer between that device and your PC. The required software plays a role by providing the necessary operating system applications for the management of that data.
How Do you use hashash?
Hashash is a term that can refer to various contexts, but if you're referring to using "hash" in programming or data management, it typically involves using hash functions to convert data into a fixed-size string of characters, which can be used for quick data retrieval or verification. In many programming languages, you can use built-in libraries or functions to generate hashes. For example, in Python, you can use the hashlib library to create hashes of strings or files. Always ensure that you choose the appropriate hash function based on your use case, such as SHA-256 for security purposes.
What is the best way of referring to the output of a secure hash function?
The output from a hash function is referred to as the hash value, hash code, hash sum, checksum or just plain "hash" as in "the hash of the file is...". Generally a hash function is presumed to be secure or it wouldn't be used. If a hash is not secure it could be referred to as "worthless" or "false sense of security".
What is hash key?
hash key is an element in the hash table. it is the data that you will combine (mathematical) with hash function to produce the hash.
What is a hash function?
hash function is technique used in message authentication it is attached to the message for security purpose
Insert value into hash table?
Insertion in hash tables is based on a 'key' value which is calculated on the basis of a hash function. This hash function generates the key based on what type of data it is fed. For example hash function for an integer input might look like this : int hash(int val) { return (val%101); } where return value of hash function would become a key.

What is double hashing in data structure?
if collision is occurred in hash function then we can solve this problem by using double hash function
What is a decryption of the hash string 108933322ed670db49b0141d10f6dbbe?
To decode a hash string you first need to know what hash function was used to encode it.
What changes in HMAC are required in order to replace one underlying hash function with another?
To replace an underlying hash function in HMAC, you need to modify the way the hash function is used within the HMAC algorithm, such as the block size and padding. You may also need to adjust the way the key is processed in the HMAC calculation based on the requirements of the new hash function. It is important to ensure that the security properties of the new hash function align with the security assumptions of HMAC.
Define hashing and describe briefly including types of hashing and where it is used and advantages and disadvantages of hashing?
Hashing is performed on arbitrary data by a hash function. A hash function is any function that can convert data to either a number or an alphanumeric code. There are possibly as many types of hashing as there are data. How precisely the hash function works depends on what data it is meant to generate a hash code from. Hashing is used for a variety of things. For example, a hash table is a data structure used for storing data in memory. Instead of iterating through the structure to find a specific item, we associate a key (hash code) to a particular item (data). A hash code can be generated from a file or disk image. If the data does not match the code, then the data is assumed to be corrupted. Hashing has the advantage of taking a larger amount of data and representing it as a smaller amount of data (hash code). The code generated is unique to the data it came from. Generating a hash code can take time however, depending on the function and the data. Some hash functions include Bernstein hash, Fowler-Noll-Vo hash, Jenkins hash, MurmurHash, Pearson hashing and Zobrist hashing.
What is the major advantage of a hash table?
The major advantage of a hash table is its speed. Because the hash function is to take a range of key values and transform them into index values in such a way that the key values are distributed randomly across all the indices of a hash table.
What Changes in HMAC is required in order to replace one underlying hash function with another?
To replace one underlying hash function in HMAC with another, you need to change the hashing algorithm used in the HMAC computation. This involves updating the HMAC implementation to utilize the new hash function while ensuring that the key and message input formats remain consistent. Additionally, the output length may differ based on the new hash function, so it's essential to adjust any downstream processes that depend on the HMAC output accordingly. The core HMAC structure remains unchanged; only the hash function used for the final computation is modified.
How do you decyrpt the MD5 hash string?
The MD5 hash algorithm is a cryptographic hash function, not an encryption method. A cryptographic hash function converts a message of variable length to a fixed size of 'hash,' usually done to check the integrity and authenticity of the original message, and not transmit the message itself in a unreadable encrypted way. The message is also sent ALONG with the hash, usually to ensure that the original message has not been altered en route. Thus it does not have enough information to actually retrieve the message itself. (although it can if the size of the message is the size of the hash, it is never the case.) Decrypting the MD5 hash string will not yield the information that was used for its creation anyways.
What are the three rules for a forensic hash?
The same input will always produce the same hash. It is a one-way function, meaning it is difficult to reverse the process and obtain the original input from the hash. A small change in the input will produce a significantly different hash value.
