Hash Generator
Compute MD5, SHA-1, SHA-256, and SHA-512 digests at once for checksums, API signature debugging, and comparisons.
Tool guide
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.
