What does this tool do?
The Password Hasher instantly converts your input text, plus an optional salt, into four different digests: SHA-256, SHA-512, FNV-1a (32-bit) and Adler-32. Because the SHA values are computed with the browser's Web Crypto API, it's handy for developers who want quick checks and comparisons.
How to use it
- Choose the required options or length.
- Generate the secure result.
- Copy and store the result safely.
What the salt field does
When you enter a value in the salt field, the tool appends it to your text before hashing. The same text with different salts produces completely different digests, a classic technique that stops identical passwords from sharing the same hash. Here the salt is simply concatenated, so you can see for learning purposes how a salt changes the output or generate your own comparison values quickly.
Important security note
The tool shows this warning directly: SHA families are far too fast for storing passwords in production. For real password storage, use intentionally slow algorithms with proper key stretching such as bcrypt, Argon2 or scrypt. This hasher is best suited for file integrity checks, checksum verification, and learning how digests behave rather than securing live credentials.
Frequently asked questions
Which hash algorithms are supported?
Four digests are shown at once: SHA-256, SHA-512, FNV-1a (32-bit) and Adler-32. The SHAs are cryptographic, while the other two are fast checksums.
Can I use this to store passwords?
No. As the tool's warning states, SHA is too fast for password storage. Use bcrypt, Argon2 or scrypt in production instead.
Do the hashes update as I type?
Yes. Every time you change the text or salt, all four digests are recalculated instantly, with no separate button needed.
Is Password Hasher free?
Yes. Password Hasher and all 300+ tools on MagmaNex are completely free with no signup or account required.
