Which is the correct description of a hash result as it relates to digital certificates?

A hash result in digital certificates is a unique, fixed-size value computed from input data, primarily used to ensure data integrity.

AA unique value used to verify the input data
BAn output value that is used to identify the person or deuce that authored the input data.
CAn obfuscation used to mask the input data.
DAn encrypted output value used to safe-guard die input data Answer: A

AA unique value used to verify the input data

BAn output value that is used to identify the person or deuce that authored the input data.

Hashes do not identify the author; digital signatures, which use hashing and encryption, identify the author.

CAn obfuscation used to mask the input data.

Hashing is not an obfuscation; it's a one-way function for integrity checks, not for hiding data.

DAn encrypted output value used to safe-guard die input data Answer: A

A hash is not encrypted; it is a one-way mathematical function that produces a unique output, but it doesn't safeguard the data itself.
