How many characters long is the fixed-length MD5 algorithm checksum of a critical system file?
How many characters long is the fixed-length MD5 algorithm checksum of a critical system file?
The MD5 algorithm produces a hash value that is 128 bits long. When represented as a hexadecimal string, each of the 128 bits is represented by 4 bits, resulting in a 32-character string. Therefore, the fixed-length checksum of an MD5 hash is 32 characters long.
The answer is correct, 32 characters. https://stackoverflow.com/questions/6317276/md5-is-128-bits-but-why-is-it-32-characters#
The correct answer is D. 16. The MD5 algorithm produces a 128-bit hash value, which is typically represented as a 32-character hexadecimal string, but in terms of raw bytes, it is 16 bytes long.
It doesn't matter whether we take a hash of system file or ordinary file. MD5 length is 128 bits. In chars it is 16 chars. 128/8 = 16. https://en.wikipedia.org/wiki/MD5
But it does matter since its asking for the checksum. Not the fixed length output
You are correct on 16 byte length due to 128 bits. each byte is 2 characters though. 16 x 2 = 32 characters
16 characters
Check zenguyaz source, its 16 bytes that part of your answer is correct but each byte is made up of 2 characters; hence 32 characters in length
the digest is represented as hex so 2 char per byte, 128 / 8 = 16 * 2 = 32
32 characters
C is correct
In the question they asked how many characters, not how many bytes (How many characters......), the answer was C 32 characters.
