What are Cryptographic Hash Functions?
A cryptographic hash function takes an input (or message) and returns a fixed-size string of bytes. The output (hash value) is typically a hexadecimal string. The same input always produces the same hash, but even a single character change completely alters the output (avalanche effect). Hash functions are one-way — you cannot reverse-engineer the original input from the hash.
SHA-256 vs SHA-512 vs SHA-1
- SHA-256: Part of the SHA-2 family. Produces a 256-bit (64 hex character) hash. Industry standard for data integrity and digital signatures. Used in Bitcoin, SSL/TLS, and most modern security protocols.
- SHA-512: Also SHA-2 family. Produces a 512-bit (128 hex character) hash. More secure but slower than SHA-256. Used in high-security applications.
- SHA-1: Produces a 160-bit (40 hex character) hash. Considered cryptographically weak — vulnerable to collision attacks. Not recommended for security-critical uses, but still used for checksums.
