About Cryptographic Hash Functions

A hash function converts arbitrary data into a fixed-length string (one-way). The same input always produces the same hash, but it is computationally infeasible to reverse the hash back to the original data. Common uses: • File integrity verification • Digital signatures • Data deduplication • Password storage (use bcrypt/argon2 in practice)

FAQ

What is the difference between hashing and encryption?
Hashing is a one-way function — the original data cannot be recovered. Encryption is two-way and can be reversed with a key. Use hashing (bcrypt, argon2) for password storage and encryption (AES) for data protection.
Is it safe to use MD5 or SHA-1?
No, for security purposes. Both have demonstrated collision attacks. Use them only for non-security tasks like file checksums. For security, use SHA-256 or stronger.
Why do I get a different hash for the same text?
Invisible differences like whitespace, line endings (LF vs CRLF), or encoding (UTF-8 vs other) change the byte representation. Hashes are computed byte-by-byte, so any difference produces a completely different result.
Can I use SHA-256 for password storage?
Not recommended. SHA-256 is too fast, making it vulnerable to brute-force attacks. Use slow key derivation functions like bcrypt, scrypt, or argon2 for passwords.
