Frequently Asked Questions
What is a hash?▾
A cryptographic hash is a fixed-size string generated from input data. The same input always produces the same hash, but you cannot reverse a hash back to the original data. Hashes are used for password storage, file integrity checks, and digital signatures.
Which hash algorithm should I use?▾
Use SHA-256 for most purposes — it's secure and widely supported. Avoid MD5 and SHA-1 for security-critical applications as they have known vulnerabilities. SHA-512 offers the highest security margin.
Is MD5 still safe to use?▾
MD5 is broken for security purposes — collisions can be generated in seconds. It's still fine for non-security uses like checksums or cache keys, but never use it for passwords or digital signatures.
