What is SHA1?
SHA1 (Secure Hash Algorithm 1) is a cryptographic hash function that produces a 160-bit hash value. It was widely used for data integrity and verification.
Is SHA1 secure?
No. SHA1 is considered broken for security purposes due to collision attacks. It should not be used for passwords or sensitive data.
When to use SHA1?
- Legacy systems
- File integrity checks (non-critical)
- Backward compatibility
Tip
For modern security, use stronger algorithms like SHA256 instead of SHA1.
