SHA-1 Generator
Secure Hash Algorithm 1. Produces a 160-bit (40-character) hash value.
Security Warning: SHA-1 is no longer considered secure against well-funded attackers. It should not be used for password hashing or sensitive cryptographic signatures. It is primarily used for non-cryptographic integrity checks (like Git) or legacy support.

What is SHA-1?
SHA-1 stands for Secure Hash Algorithm 1. It was designed by the NSA and published in 1995. It produces a 160-bit (40-character) message digest. While once widely used in many security protocols, it is now considered cryptographically broken and is primarily used for non-security purposes like data integrity in version control systems.
Properties
- Deterministic: Same input always produces the same output.
- Fixed Length: Always produces a 160-bit (40 hex characters) output.
- Efficiency: Fast computation on most modern hardware.
- Legacy: Widely supported across older systems and legacy applications.
