Understanding Data Transformation Techniques

What is the primary purpose of encoding?

• To make data harder to understand

• To validate data integrity

• To ensure data confidentiality

• To maintain data usability

Which of the following requires a key to transform data back to its original form?

• Encoding

• Obfuscation

• Encryption

• Hashing

What is a key characteristic of hashing?

• It makes data harder to understand

• It produces a fixed-length output

• It uses a secret key

• It can be easily reversed

Which technique is primarily used to ensure data integrity?

• Obfuscation

• Hashing

• Encryption

• Encoding

What is the main goal of obfuscation?

• To make data harder to understand

• To ensure data confidentiality

• To maintain data usability

• To validate data integrity

Which of the following is an example of an encryption algorithm?

• SHA-3

• JavaScript Obfuscator

• ASCII

• AES

What is a common use of obfuscation?

• To produce a fixed-length string from arbitrary input

• To make source code harder to replicate

• To transform data into another format using a public scheme

• To securely send a password over the Internet

Which of the following is NOT a characteristic of hashing?

• It produces a fixed-length string

• It detects modifications via changes to the hash output

• It can be reversed to obtain the original input

• The same input always produces the same output

Which technique is used to transform data so that only specific individuals can reverse it?

• Encryption

• Encoding

• Hashing

• Obfuscation

What is a limitation of obfuscation?

• It cannot be reversed

• It always produces a fixed-length output

• It requires a secret key

• The result must still be consumable by the computer
