Secure Hash Algorithms (SHA) are a family of cryptographic hash functions designed by the NSA. They are widely used for security applications and data integrity verification.

How to Use SHA Generator

1. Enter the text or string you want to hash in the input field.
2. Select the desired SHA algorithm (SHA-1, SHA-256, SHA-384, or SHA-512) from the dropdown.
3. Choose the output format (Lowercase or Uppercase).
4. The hash will be generated automatically as you type, or you can click the “Generate” button.
5. Copy the resulting hash for your use.

Available Algorithms

• SHA-1: Produces a 160-bit (40-character) hash. No longer considered secure for cryptographic purposes but still used for non-security tasks like Git checksums.
• SHA-256: Part of the SHA-2 family, produces a 256-bit (64-character) hash. It is currently one of the most widely used hash functions (e.g., in Bitcoin).
• SHA-384: A more secure version of SHA-2, producing a 384-bit (96-character) hash.
• SHA-512: The strongest of the SHA-2 family, producing a 512-bit (128-character) hash.

Note: For modern security needs, SHA-256 or higher is recommended. SHA-1 is considered weak and should be avoided for sensitive data.
