Our **SHA-1 Generator** allows you to compute 160-bit cryptographic hashes for text or files. While no longer recommended for high-security applications, it remains a pillar for version control systems like Git and legacy software integrations.
How to Use
- Type or paste your data into the input box.
- Select SHA-1 to see the 40-character hexadecimal result.
- Compare results using the match detection feature.
- Copy or download the hash instantly.
