What is a hash function?
A hash function turns any input into a fixed-length string of characters. The same input always produces the same output, and changing even one character produces a completely different hash — useful for verifying file integrity or comparing values without exposing the original data.
Is MD5 still safe to use?
MD5 and SHA-1 are considered cryptographically broken for security purposes (they're vulnerable to collision attacks) and are included here only for checksums and legacy compatibility. For anything security-related, use SHA-256 or higher.
What's the difference between SHA-256 and SHA-512?
Both are secure. SHA-512 produces a longer hash and is often faster on 64-bit systems, while SHA-256 is more widely used in existing standards like TLS certificates and Bitcoin.
Can a hash be reversed back to the original text?
No, hash functions are one-way by design. You can only verify a match by hashing the same input again and comparing the results.
