Frequently asked questions
What's the difference between MD5, SHA-1, and SHA-256?
▾
MD5 and SHA-1 are cryptographically broken — collision attacks exist for both. SHA-256 (part of SHA-2) is still secure and the current standard for most use cases.
Can I reverse a hash?
▾
No. Hashing is a one-way function by design. You can only verify data by hashing the candidate and comparing the output. Rainbow tables can crack weak/common inputs — always salt passwords.
When is MD5 still acceptable?
▾
Only for non-security purposes: checksums, file deduplication, cache keys, or non-cryptographic identifiers where speed matters. Never use MD5 for passwords, digital signatures, or certificate fingerprints.
What is SHA-512 useful for?
▾
Same security model as SHA-256 but with a 512-bit output. Useful when you want extra collision resistance margin. It's also faster than SHA-256 on 64-bit hardware.
