What are the examples of key stretching algorithms?
- What are the examples of key stretching algorithms? BCRYPT: BCRYPT is a password-hashing algorithm based on the Blowfish cipher. PBKDF2: PBKDF2 stores passwords with a random salt and with the password hash using HMAC; it then iterates, which forces the regeneration of every password and prevents any rainbow table attack.

Which of the following is NOT used for hashing passwords?
Passwords should be hashed with either PBKDF2, bcrypt or scrypt, MD-5 and SHA-3 should never be used for password hashing and SHA-1/2(password+salt) are a big no-no as well.
What can be used to increase the strength of hash password?
Ensure that the salt is unique for every user and for every password. Using ten different salts increases the security of hashed passwords by increasing the computational power required to generate lookup tables by a factor of ten.
Which of the following is a is a two way relationship that is automatically created between parent and child domains in a Microsoft Active Directory forest?
Transitive trust is a two-way relationship automatically created between parent and child domains in a Microsoft Active Directory forest. When a new domain is created, it shares resources with its parent domain by default, enabling an authenticated user to access resources in both the child and parent.
What is password hash algorithm?
Hashing performs a one-way transformation on a password, turning the password into another String, called the hashed password. “One-way” means that it is practically impossible to go the other way – to turn the hashed password back into the original password. If the passwords match, then login is successful.
Which of the following is a password hashing algorithm?
Commonly used hashing algorithms include Message Digest (MDx) algorithms, such as MD5, and Secure Hash Algorithms (SHA), such as SHA-1 and the SHA-2 family that includes the widely used SHA-256 algorithm.
How does key stretching work?
Key stretching is the practice of converting a password to a longer and more random key for cryptographic purposes such as encryption. This is generally recognized as making encryption stronger as it ensures that the encryption itself is reasonably hard.
What is a hashing algorithm used for?
Hashing algorithms are functions that generate a fixed-length result (the hash, or hash value) from a given input. The hash value is a summary of the original data. For instance, think of a paper document that you keep crumpling to a point where you aren’t even able to read its content anymore.
What is MD5 algorithm in cryptography?
Message Digest Algorithm 5 (MD5) is a cryptographic hash algorithm that can be used to create a 128-bit string value from an arbitrary length string. MD5 is most commonly used to verify the integrity of files. However, it is also used in other security protocols and applications such as SSH, SSL, and IPSec.
What is the main weakness associated with the use of passwords quizlet?
Passwords provide strong protection. What is the main weakness associated with the use of passwords? limitations in human memory. What type of attack involves using every possible combination of letters, numbers, and characters to create candidate digests that are then matched against those in a stolen digest file?
What is credit card debit card and smart card?
Smart card is again similar to a credit card or a debit card in appearance, but it has a small microprocessor chip embedded in it. It has the capacity to store a customer’s work-related and/or personal information. Smart cards are also used to store money and the amount gets deducted after every transaction.
What is smart card security?
Smart cards provide ways to securely identify and authenticate the holder and third parties who want to gain access to the card. For example, a PIN code or biometric data can be used for authentication. They also provide a way to securely store data on the card and protect communications with encryption.
Which type of trust relationship is set up manually?
Another trust that can be set up manually is a realm trust. This is useful for communication between Microsoft-based networks and non-Microsoft networks.
What is a two-way trust in Active Directory?
A two-way trust relationship consists of two one-way trusts in opposite directions. By default in Active Directory, all domains in a forest trust each other with two-way transitive trust relationships. You can also create shortcut trusts between child domains to facilitate rapid authentication and resource access.
How do you trust a relationship between two domains?
- Open the Active Directory Domains and Trusts snap-in.
- In the left pane, right-click the domain you want to add a trust for, and select Properties.
- Click on the Trusts tab.
- Click the New Trust button.
- After the New Trust Wizard opens, click Next.
- Type the DNS name of the AD domain and click Next.
