AldeaCode Hash Generator vs sha-256.com
Both produce a SHA-256 hash from a string. AldeaCode also covers SHA-1, SHA-384, SHA-512 and MD5, with a clear 'never use MD5 for passwords' warning. The honest comparison is below.

Where AldeaCode wins
Five algorithms in one place
Most hashing tasks are not 'I want a SHA-256 specifically', they are 'I have a checksum from a download page and I do not yet know which algorithm produced it'. AldeaCode lets you compute all five and eyeball which one matches in a single page. sha-256.com forces you to navigate to its sister sites for SHA-1 or MD5, which is fine if you already know the algorithm and slow if you do not.
Honest password-safety warning
If you type a password into a hash tool there is a real chance you are about to do something unsafe with it: store hashed passwords in your own database with no salt, validate against a hash a colleague generated, send a hash over an unauthenticated channel. AldeaCode shows a callout that hashing alone is not how you store passwords (use bcrypt, scrypt, argon2id, or a managed service). sha-256.com just hands you the hash with no context.
Web Crypto API everywhere
All five algorithms use the browser's built-in Web Crypto API where possible, falling back to a tiny pure-JS implementation only for MD5 (which the standard Web Crypto API does not expose). That means the heavy lifting is done by native code, the page stays fast, and there is zero network round-trip. Your input never leaves the tab.
Where sha-256.com wins
sha-256.com has the literal exact-match domain for the most-searched algorithm, so for raw 'where do I get a SHA-256 of this string' Googling they are usually the first organic result and they load fast. The page does one thing and does it well, with no extra UI to scroll past. If you only ever need SHA-256 and you are not interested in any of the other algorithms, their page is genuinely fine and the bookmark is worth keeping.
When to pick which
Pick AldeaCode if
- You do not yet know which hash algorithm produced your checksum.
- You want a clear 'do not use MD5 for passwords' warning before you ship something dangerous.
- You also want SHA-1, SHA-384 or SHA-512 in the same page.
- You want a Spanish-language UI, not a translation.
Pick sha-256.com if
- You only ever need SHA-256 and you have it bookmarked already.
- You want the smallest possible single-purpose page.
The verdict
Need to hash a string and you do not know whether the checksum on the download page is SHA-1, SHA-256 or SHA-512? Open the AldeaCode hash tool and you have all of them at once with a clear password-safety warning. If you only ever need SHA-256 and have sha-256.com bookmarked, that page also gets the job done. Pick what fits the input you actually have.
Open SHA Hash Generator →Frequently asked questions
Why does AldeaCode warn against MD5 for passwords?
Because MD5 is collision-broken and orders of magnitude too fast for password storage. A modern GPU can brute-force billions of MD5 candidates per second, which means a leaked MD5 password database is effectively plaintext. SHA-256 alone has the same problem, just slightly slower. For passwords, use a deliberately slow algorithm with salt: bcrypt, scrypt, or argon2id.
Can I hash a file with AldeaCode?
Not currently, the input is a text box. For file hashing we recommend the system shasum or certutil command lines, both of which run locally and handle large files. We may add file input in a future release.
Does the hash leave my browser?
No. Web Crypto runs natively in the browser and AldeaCode does not call any external endpoint. You can disconnect the network and keep hashing; the page works offline once loaded.
