💡 Tips
- • SHA256 is a cryptographic hash function that produces a 256-bit (32-byte) hash
- • The same input will always produce the same hash (deterministic)
- • Even a small change in input produces a completely different hash
- • SHA256 is widely used for password hashing, digital signatures, and data integrity
- • Hexadecimal output is most common, but Base64 is useful for URLs and APIs
- • Use UTF-8 encoding for most text inputs to ensure consistent results
