SHA-1 hash generator
Create a SHA-1 hash shown as a hexadecimal value.
Create a SHA-1 checksum from text. SHA-1 is not safe for passwords.
About this tool
The SHA-1 hash generator converts text into a fixed 40-character hexadecimal checksum. Use it to verify legacy test cases, compare exported text, or work with a system that still expects SHA-1 values. SHA-1 no longer offers collision resistance for security work. Do not use it for passwords, digital signatures, or new integrity designs. SHA-256 is a better choice for modern checksums.
