How many characters long is the fixed-length MD5 algorithm checksum of a critical system file?

The correct answer is B. 32. MD5 produces a 128-bit hash value. When represented as a hexadecimal string (the most common format), each 4 bits is represented by one hex character, so 128 bits ÷ 4 = 32 hexadecimal characters. For example, an MD5 hash looks like: d41d8cd98f00b204e9800998ecf8427e - exactly 32…

Explanation

MD5 produces a 128-bit hash value. When represented as a hexadecimal string (the most common format), each 4 bits is represented by one hex character, so 128 bits ÷ 4 = 32 hexadecimal characters. For example, an MD5 hash looks like: d41d8cd98f00b204e9800998ecf8427e - exactly 32 characters. This fixed-length output regardless of input size is a fundamental property of cryptographic hash functions.
