About Hash Functions
What is a Hash Function?
A hash function is a mathematical algorithm that maps data of arbitrary size to a fixed-size string of characters. It is designed to be a one-way function, meaning it's easy to compute a hash from the input data, but computationally infeasible to generate the original input from the hash.
Common Uses
- Password storage and verification
- Data integrity checks
- Digital signatures
- File identification
Algorithm Differences
MD5: Produces a 128-bit hash value, now considered insecure for cryptographic purposes.
SHA-1: Produces a 160-bit hash value, also considered insecure for cryptographic purposes.
SHA-256: Part of the SHA-2 family, produces a 256-bit hash value, widely used in modern applications.
SHA-512: Also part of the SHA-2 family, produces a 512-bit hash value, provides higher security but with larger output.
CRC32: A checksum algorithm, not cryptographic, used mainly for error detection.
