Frequently Asked Questions
Which algorithm should I use?
For security: SHA-256 or SHA-512. MD5 and SHA-1 are broken for security (collisions can be engineered) but still used for file integrity checksums.
What is a hash collision?
When two different inputs produce the same hash. MD5 and SHA-1 have known collision attacks. SHA-256 and SHA-512 have none.
Can I reverse a hash?
No — hashes are one-way by design. Short/common inputs can be looked up in rainbow tables. Always salt passwords before hashing.
What is a checksum?
A hash used to verify file integrity. Software publishers list the SHA-256 so you can confirm your download is genuine.
How do I verify a download?
Generate the hash of your downloaded file here, then compare it to the publisher's listed hash. If they match, the file is unmodified.
