About Hash Functions
🔐 What is a Hash?
A hash function takes any input and produces a fixed-length string. The same input always produces the same output — but you cannot reverse it to get the original data.
⚠️ MD5 & SHA-1
MD5 (128-bit) and SHA-1 (160-bit) are considered cryptographically broken for security purposes, but still widely used for checksums and non-security file verification.
✅ SHA-256 & SHA-512
SHA-256 and SHA-512 (from the SHA-2 family) are currently secure and recommended for cryptographic use, including TLS certificates, code signing and password hashing.
