About Hash Functions
A hash function is any function that can be used to map data of arbitrary size to fixed-size values. The values returned by a hash function are called hash values, hash codes, digests, or simply hashes.
Common uses of hash functions include data integrity verification, password storage, and digital signatures.
Understanding Hash Functions
Hash functions are mathematical algorithms that convert input data of any size into a fixed-size output called a hash. They're fundamental to modern cryptography and data integrity verification.

Hash Algorithms Explained
MD5
128-bit hash, fast but cryptographically broken. Use only for non-security purposes like checksums.
SHA-1
160-bit hash, deprecated for security. Still used in legacy systems but not recommended for new implementations.
SHA-256
256-bit hash, widely used and secure. Standard for blockchain, digital signatures, and password hashing.
SHA-512
512-bit hash, more secure but slower. Recommended for high-security applications where performance isn't critical.
