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.
How can you put a password in matlab?
In MATLAB, you can prompt the user for a password using the input function with the 's' option for string input. To mask the input for security, you can use the inputdlg function from the uicontrol toolbox, or implement a custom function to hide the input. For example: password = input('Enter your password: ', 's'); To ensure it's secure, you should compare the entered password against a stored hash rather than storing plaintext passwords.
How do you create hash of password?
I'm not sure i got your question right or not, but if you mean how to encrypt password for saving or ect, use md5 function
What does the term "hash" mean in programming and how is it used in software development?
In programming, "hash" refers to a function that converts input data into a fixed-size string of characters. This string is unique to the input data, making it useful for storing and retrieving data quickly in software development. Hash functions are commonly used for tasks like data encryption, password storage, and indexing in databases.
How do you get a Windows XP password from a password hash?
There are several tools that will determine the password from the hash. You can find them via any Internet search engine.
What is lamport hash?
Lamport's hash implements a one-time password protecting against eavesdropping and password file theft.
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".
How to maintain transaction integrity using hash function?
To maintain transaction integrity using a hash function, each transaction can be represented by a unique hash value generated from its content. This hash serves as a digital fingerprint, ensuring that any alteration to the transaction data will result in a different hash. By storing the hash of previous transactions in a blockchain or a similar structure, any tampering can be easily detected, as the hash will not match the expected value. Regularly verifying these hashes against the original data helps to ensure ongoing integrity throughout the transaction lifecycle.
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.

How can you reset the BIOS password on a HP nx9010 laptop. i have tried the remove the battery system that doesn't work for me. can anyone help?
"Yes. Call 784-2751, And You'll get help." you can also get the hash key, by entering the password 3 times incorrectly then pressing F12 on the 3rd password attempt, you will get the 5 digit hash. you can then go to this site http://dogber1.blogspot.com/2009/05/table-of-reverse-engineered-bios.html and download the software for your machine (hewlett packard) and run the program pwgen-5dec.exe this will open in a DOS window if you are running windows. the program will ask you to enter your 5 digit hash it will then generate the master password for your machine. the password you will need is listed under the Hp/Phoenix password. good luck!
