⚠️ Do not use SHA-1 for security

SHA-1 is considered cryptographically broken. Use SHA-256 or higher for all security-sensitive applications.

How SHA-256 works

SHA-256 is a cryptographic hash function that produces a fixed 256-bit (64-character hex) output. Even a tiny change in the input produces a completely different hash. It is one-way — you cannot reverse a hash to get the original input.
