SHA-1 Hash Function
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-digit hexadecimal number.
Although SHA-1 is no longer considered secure against well-funded collision attacks, it is still widely used for data integrity checks (e.g., Git) and in legacy systems.
Key Characteristics:
- Output Size: 160 bits (20 bytes).
- Usage: Version control systems, legacy certificates, checksums.
- Status: Deprecated for cryptographic security; use SHA-2 or SHA-3 instead.
