When hashing helps
Hashes are useful when you want to compare values, verify a file, or generate a digest another system expects.
They're one-way transformations, so they're good for verification and matching, not for getting the original text back.

Hash Generator
Generate MD5, SHA-1, SHA-256, or SHA-512 hashes for text, fixtures, payloads, and quick integrity checks.
Hashing is one-way. Use it for checksums and signatures, not for reversible storage.
FAQ
Is this hash generator free?
Yes.
Which algorithms does it support?
The tool supports MD5, SHA-1, SHA-256, and SHA-512.
Is hashing the same as encryption?
No. Hashing is one-way and cannot be reversed into the original input.
Is my data uploaded anywhere?
No. Hashes are generated locally.
Why would I still need MD5?
Mostly for compatibility with older systems, fixtures, or APIs that still expect MD5 digests.
Can I use this for password storage?
No. Password storage needs a password-specific scheme, not a plain MD5 or SHA hash.
How To Use It
Choose modern algorithms when possible
If you're choosing from scratch, SHA-256 or SHA-512 is the sensible default.
MD5 and SHA-1 still come up for compatibility, but they're not what you want for security-sensitive work.
Good use cases before launch
Typical use cases are fixture values, checksum examples in docs, and quick comparisons between files or payloads.
They also help when you're checking whether two parts of a pipeline really saw the same input.
