About Detect Hash Length
Detect Hash Length measures the length of the string you paste and computes the equivalent size in bits and bytes assuming a hexadecimal representation (each hex character = 4 bits).
Knowing the length is the first step to identifying an algorithm: 32 chars → 128-bit (MD5), 40 → 160-bit (SHA-1), 64 → 256-bit (SHA-256), and so on. To identify the algorithm name, use the Hash Identifier.
