Hash Generator
Compute MD5, SHA-1, SHA-256, and SHA-512 digests at once for checksums, API signature debugging, and comparisons.
How to use the hash generator
Enter any text to generate multiple digests at once. The same input always yields the same output; changing even one character changes the result — useful for integrity checks and signature debugging. A hash is a one-way digest, not encryption.
- MD5：Fine for legacy systems or casual checksums — not for security
- SHA1：Still usable for non-security checks, but not recommended for digital signatures
- SHA256：Common for API signatures, content digests, and integrity checks
- SHA512：Longer output for cases that need a larger digest
FAQ
Can MD5 still be used for passwords?
Not recommended. MD5 and a single SHA pass are not suitable for storing passwords — use salted schemes like Argon2, scrypt, or bcrypt.
Can a hash be decrypted?
You cannot decrypt it. A hash is a one-way digest; you usually recompute the input and compare results.
Is the calculation done locally?
Yes. Text is hashed in the browser; the page never uploads your input.
