Frequently Asked Questions
What is a hash?
A cryptographic hash is a fixed-length string produced from input data by a mathematical function. The same input always produces the same hash, but even a tiny change in input completely changes the output. Hashes are one-way — you cannot reverse them to get the original input.
Which hash algorithm should I use?
Use SHA-256 or SHA-512 for modern applications. MD5 and SHA-1 are considered cryptographically broken for security purposes (collision attacks exist) but are still used for file checksums and non-security integrity checks.
Can I use this for password hashing?
No. MD5/SHA hashes are too fast for password storage — they can be brute-forced with GPUs. For passwords, use bcrypt, scrypt, or Argon2 with a salt. This tool is for data integrity, file verification, and checksums.
