FAQ

Which hash algorithm should I use?

Use SHA-256 for most security purposes (password verification, file integrity, digital signatures). SHA-512 for extra security. Avoid SHA-1 for security-critical applications as it has known collision vulnerabilities.

Can a hash be reversed?

No. Cryptographic hash functions are one-way — you cannot recover the original input from a hash. This is by design and is what makes them useful for password storage and integrity checks.
