Frequently Asked Questions
A hash function takes any input and produces a fixed-size output (hash). The same input always produces the same hash, but any small change in input completely changes the hash. It's a one-way function — you can't reverse it.
MD5 produces a 128-bit (32 hex character) hash and is now considered cryptographically broken for security use. SHA-256 produces a 256-bit (64 hex character) hash and is still secure. Use SHA-256 or SHA-512 for security-sensitive applications.
MD5 and SHA for passwords is a bad practice. For password hashing, use bcrypt, Argon2, or scrypt — designed to be slow and resist brute force. MD5/SHA are too fast and can be cracked easily with rainbow tables.
SHA-512 (512-bit hash) is used for high-security applications like TLS certificates, digital signatures, and integrity verification where maximum security is required.
No. Encryption is reversible (decrypt with a key). Hashing is one-way — you can't reverse a hash to get the original input. Hashing verifies integrity; encryption protects confidentiality.
