How to use it
- 1 Paste or type text into the input panel.
- 2 Choose the SHA algorithms you want to generate.
- 3 Copy the hash output you need for checks, logs, or comparisons.
Useful for
- Generating SHA-256 values for debugging and integrity checks
- Comparing whether two text inputs hash to the same result
- Inspecting legacy SHA-1 values while migrating older workflows
Good to know
- This first version hashes text only, not uploaded files.
- Whitespace and line endings change the resulting hash.
- Hashes are one-way values and do not prove authenticity without a trusted expected hash.
Questions
Hash Generator FAQ
Does the Hash Generator upload my text?
No. Hashing runs in your browser with Web Crypto, so Utilshub does not receive the input or generated hash values.
Is hashing the same as encryption?
No. Hashing is one-way and is meant for fingerprints or comparisons, not for hiding text or recovering the original value.
Why is SHA-1 marked as legacy only?
SHA-1 is no longer recommended for new security-sensitive work because collision resistance is considered weak compared with SHA-256 and stronger algorithms.
Can I hash uploaded files here?
Not in this first version. The current tool is focused on text hashing only to keep the workflow simple and reliable.
