MD5
MD5 - 128-bit hash, fast but not secure for cryptographic purposes
SHA-1
SHA-1 - 160-bit hash, deprecated for security use
SHA-256
SHA-256 - 256-bit hash, secure and widely used
SHA-512
SHA-512 - 512-bit hash, most secure option
Frequently asked questions
Which hash algorithm should I use?
For security purposes, use SHA-256 or SHA-512. MD5 and SHA-1 are considered cryptographically broken and should only be used for non-security purposes like checksums or cache keys.
Can I reverse a hash to get the original text?
No, hash functions are one-way by design. You cannot decrypt a hash. This is why they're used for password storage—even if stolen, the original password can't be recovered.
Why are my file hashes different from others?
Even tiny differences produce completely different hashes. Ensure you're comparing the exact same file without any modifications, downloads corruptions, or character encoding differences.
