About SHA-1
What is SHA-1?
SHA-1 (Secure Hash Algorithm 1) is a cryptographic hash function that produces a 160-bit (20-byte) hash value, typically rendered as a 40-character hexadecimal number. It was designed by the NSA and published in 1995.
Features
- Generates 160-bit (40 hex character) hash
- Faster than SHA-256 but less secure
- Deterministic output
- One-way function
- Supports text and file hashing
