SHA-1 Hash Generator for Legacy Systems
Generate SHA-1 hashes for legacy checksums and compatibility.
SHA-1 Hash Generator
Generate SHA-1 hashes for legacy compatibility and checksum workflows. This is useful when you must match existing SHA-1 values in older systems.
How to use the SHA-1 Hash Generator
- Paste your text or value.
- Click Generate.
- Copy the SHA-1 hash output.
Common use cases
- Matching legacy SHA-1 checksums.
- Verifying existing artifacts in older pipelines.
- Comparing historical hash values.
- Debugging systems that still use SHA-1.
Tips & notes
- SHA-1 output is always 40 hex characters.
- Identical input always produces identical output.
- Prefer SHA-256 for modern security needs.
Safety note
SHA-1 is not suitable for passwords or security-sensitive integrity checks. Use stronger hashes such as SHA-256 for secure applications.

FAQ
Is SHA-1 secure for passwords?
No. SHA-1 is considered weak and should not be used for passwords or security-critical data.
What is SHA-1 used for today?
SHA-1 is mainly used for legacy systems, checksums, and compatibility purposes.
Do you store my input or hash?
No. All hashing is done instantly and nothing is saved.
Does the same input always generate the same hash?
Yes. SHA-1 is deterministic, so identical input always produces the same hash.
Is SHA-1 acceptable for integrity checks?
It can detect accidental changes but is weak against malicious collisions.
