About SHA Hash Functions

SHA (Secure Hash Algorithm) is a family of cryptographic hash functions published by the National Institute of Standards and Technology (NIST). They are widely used in security applications and protocols.

Algorithm Comparison

SHA-1: 160-bit hash. Now considered insecure due to collision attacks. Use only for legacy compatibility.
SHA-256: 256-bit hash. Part of the SHA-2 family. Recommended for most security applications.
SHA-384: 384-bit hash. Truncated version of SHA-512. Offers higher security than SHA-256.
SHA-512: 512-bit hash. The strongest in the SHA-2 family. Best for high-security applications.

Common Uses

Password hashing (with salt)
Digital signatures and certificates
File integrity verification
Blockchain and cryptocurrency
