Hash Generator FAQ
How do I generate a SHA-256 hash?
Type your text or upload a file and the SHA-256 hash appears instantly along with MD5, SHA-1 and SHA-512.
How do I verify a file checksum?
Upload the file and compare the generated hash with the checksum published by the download source. If they match exactly, the file is intact.
Should I use MD5 for passwords?
No. MD5 and SHA-1 are no longer considered secure for passwords. Use them only for checksums; for passwords use a dedicated algorithm such as bcrypt or Argon2.
