Frequently Asked Questions
›Which hash algorithm should I use?
For general purposes, SHA-256 is the standard choice. SHA-512 provides more bits of security. SHA-1 and MD5 are considered weak and should only be used for non-security purposes like checksums.
›Can I reverse a hash?
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 data integrity.
›Is this tool secure for hashing passwords?
This tool generates raw hashes, which is fine for checksums and data integrity. For password hashing, you should use specialized algorithms like bcrypt or argon2 that include salting and are deliberately slow.
