This strategy for cracking a has attempts every possible code until a match is found.
brute force
dictionary
rainbow table
lookup table
This type of attack against a hash attempts the common words, phrases, and passwords in a language.

Select the two basic hash algorithms listed below. (Pick2)
Message Digest 5
Secure Hash Algorithm - 1
HMAC
WPA
Select the situations listed below when hashing should be used. (Select all that apply!)
When you need to ensure file integrity.
PKI Certificates
IPsec Protocols
Routing Authentication
Challenge Response Protocols (CHAP)
Which of the following does NOT accurately describe hashing.
One way math function
Fixed Output Length
Fixed Input Length
Two different inputs almost never give the same output
This is how HMAC is different from other basic hash algorithms.
One way math function
Fixed Output Length
Requires a secret key along with the message digest
Variable Input Length
This is the purpose of CSPRNG
Perform hash calculations
Encrypt data
Generate Salts
Concatenate Strings in Programming
Which of the following is NOT a good practice when implementing salting?
Salts unique for each password
Salts are never reused
Salt lengths that are different from hash output lengths
Hashes always performed on the server
Smaller table for cracking hashes that sacrifices speed to make the table smaller.
Lookup Table
Reverse Lookup Table
Rainbow Table
Salting Table
This prevents two users with the same password from having the same hash in a data base.
Peppering
Hashing
Salting
Rainbow Table
Digital signatures cannot be repudiated. What does this mean?
They can't be reused.
They can't be altered.
It can't be denied that they happened in the future.
It can be reliably trusted
Other than verifying a person or organization, this is another thing that digital signatures get used for a lot.
Making sure social media posts are true.
Making sure GPS directions are accurate.
Verifying code integrity
Making sure students are the ones that completed homework assignment.
These are the three steps to creating a document with a digital signature, in order.
1.The digest and private key are encrypted
2.Message and message digest are created
3.The message, encrypted digest, and public key are bundled together.
1.The message, encrypted digest, and public key are bundled together.
2.The digest and private key are encrypted
3.Message and message digest are created
1.Message and message digest are created
2.The digest and private key are encrypted
3.The message, encrypted digest, and public key are bundled together.
Which of the following are NIST approved digital signature algorithms. (Pick 3)
DSA (Digital Signature Algorithm)
RSA (Rivest -Sharmire-Adleman)
ECDSA (Elliptic Curve Digital Signature Algorithm)
HMAC (Hash Message Authentication Code)
This is your first indicator that a site is using a digital certificate.
HTTPS in the URL
HTTP in the URL
A lock symbol in the browser security bar
No lock symbol in the browser security bar.
This is the standard for managing the requirement for digital certificates.
X.510
X.802.11
X.509
X.802.15
These are three validation rules for data base data. (Pick 3)
Size
Format
Check Digit
Value
Opinion
Which of the following is not one of the data integrity constraints for data bases.
Entity Integrity
Domain Integrity
Referential Integrity
User-Defined Integrity
Personal Integrity
This data base integrity constraint states that every table mush have a primary key and that columns that hold primary keys must be unique and not NULL.
Entity Integrity
Domain Integrity
Referential Integrity
User-Defined Integrity
Personal Integrity
Which of the following is NOT a strategy to ensure user input validation?
Input masks
Drop down menus
Mandatory inputs
Data ranges
Empty field requirement
