About SHA-1

SHA-1 (Secure Hash Algorithm 1) is a cryptographic hash function that takes an input (data of any size) and produces a fixed-size 160-bit (20-byte) hash value. This hash is a unique fingerprint of the input data.

Why Use SHA-1?

  • Data Integrity: Detect if data has been tampered with.
  • Password Storage: (Though deprecated for this; use stronger methods) Store passwords securely.
  • Digital Signatures: Part of digital signature schemes.

Security Note:

While SHA-1 was widely used, it is now considered cryptographically broken for security-sensitive applications. For new projects, use stronger hash functions like SHA-256 or SHA-512.

Examples

Example 1: Input: "Hello, world!" Output: (SHA-1 hash)
