What is SHA?

SHA (Secure Hash Algorithm) is a family of cryptographic hash functions designed by the NSA. They are widely used for data integrity verification and digital signatures.

SHA Variants:

SHA-1: 160-bit hash. Now considered weak due to collision vulnerabilities. Not recommended for security.
SHA-256: 256-bit hash. Part of SHA-2 family. Widely used and secure for most applications.
SHA-512: 512-bit hash. Part of SHA-2 family. More secure, used for high-security applications.
SHA-3: Latest standard (2015). Different internal structure from SHA-2. Alternative to SHA-256.

Common Use Cases:

File integrity verification (checksums)
Digital signatures and certificates
Blockchain and cryptocurrency
Git commit hashing
Password storage (with salt)

Examples (input: "hello"):

SHA-1:   aaf4c61ddcc5e8a2dabede0f3b482cd9aea9434d
SHA-256: 2cf24dba5fb0a30e26e83b2ac5b9e29e1b161e5c1fa7425e73043362938b9824
SHA-512: 9b71d224bd62f3785d96d46ad3ea3d73319bfbc2890caadae2dff72519673ca72323c3d99ba5c11d7c7acc6e14b8c5da0c4663475c2e5c3adef46f73bcdec043
