While storing passwords in MD5 is insecure today, legacy systems might still hold hashes like this.

| Algorithm | Output Size | Typical Use Cases | |-----------|-------------|-------------------| | MD5 | 128 bits | Legacy checksums, non‑security contexts (now discouraged for security). | | SHA‑1 | 160 bits | Older protocols; being phased out due to vulnerabilities. | | SHA‑256 | 256 bits | Modern security applications, blockchain, digital signatures. | | SHA‑3 | Variable (224‑512 bits) | Post‑NIST standard, alternative construction. | D63af914bd1b6210c358e145d61a8abc

Think of D63af914bd1b6210c358e145d61a8abc as a personalized locker number at a train station. You can use it to retrieve stored luggage (data), but the number itself reveals nothing about the contents. If someone steals the number, they get the luggage — hence, keep such identifiers secret when they grant access. While storing passwords in MD5 is insecure today,
