About this Tool
Use this SHA-1 generator for legacy systems and compatibility checks. SHA-1 is no longer collision-resistant and should not be selected for new security-sensitive applications.
Examples
- hello world
- Calculate a SHA-1 file checksum
- Generate a legacy SHA-1 digest
Frequently Asked Questions
What is SHA-1?
SHA-1 is a cryptographic hash function that produces a 160-bit digest.
Is SHA-1 still secure?
No. SHA-1 is vulnerable to practical collision attacks and is deprecated for digital signatures and certificates.
Why is SHA-1 still supported?
Some older systems and file repositories still publish SHA-1 values for compatibility.
