What are Cryptographic Hashes?
A cryptographic hash function takes an input and produces a fixed-size string (hash) that uniquely represents that input. Hash functions are one-way: you cannot reverse the hash to get the original input. They're used for checksums, password storage, digital signatures, and verifying data integrity.
Hash Algorithms
MD5: 128-bit hash. Fast but cryptographically broken — only use for checksums, not security. SHA-1: 160-bit hash. Deprecated for security but still used for git commits. SHA-256: 256-bit hash from the SHA-2 family. Secure and widely used for passwords and certificates. SHA-512: 512-bit hash. More secure than SHA-256 but slower.
