About the Hash Generator
Calculate common cryptographic digest values from text or a local file. Generate multiple hash formats at once, copy individual results, or compare a calculated value with an expected digest when checking integrity.
Common uses
- Verify a downloaded file against a publisher's checksum.
- Generate test values for development and data-processing workflows.
- Compare content without sharing the original text or file.
Hash Generator questions
Can a hash be reversed into the original content?
A cryptographic hash is designed to be one-way, although weak or predictable inputs may still be guessed using precomputed or brute-force attacks.
Should MD5 or SHA-1 be used for password storage?
No. MD5 and SHA-1 are unsuitable for password storage, and even general-purpose SHA hashes lack the slow, salted design of dedicated password-hashing algorithms.
