Generate SHA-1 Hash
SHA-1 produces a 160-bit (40-character hex) hash. Although deprecated for security uses due to known collision attacks, SHA-1 remains relevant in Git (which uses it for commit hashes), legacy system integration, and non-security fingerprinting.
Open Hash Generator →How to Generate SHA-1 Hash
- Open the Hash Generator tool on ToolPrime
- Type or paste your input text
- Select SHA-1 as the algorithm
- View and copy the 40-character hash result
Common Use Cases
- Compute Git-style object hashes for comparison
- Interface with legacy systems that require SHA-1 signatures
- Generate short content fingerprints for caching
Frequently Asked Questions
Is SHA-1 still safe to use?▾
SHA-1 is broken for collision resistance and should not be used for security. It is acceptable for non-security purposes like checksums and Git.
Why does Git still use SHA-1?▾
Git uses SHA-1 for content addressing, not security. Git is transitioning to SHA-256, but SHA-1 remains the default in most installations.
