What is a Hash?
A cryptographic hash function is a mathematical algorithm that maps data of arbitrary size to a fixed-size string of bytes. The output, called a hash or digest, serves as a unique fingerprint of the input data.
Key Properties
- check_circle Deterministic: Same input always produces same output
- check_circle Fixed Size: Output length is always the same
- check_circle One-Way: Cannot reverse the process to get original data
- check_circle Avalanche Effect: Small input change causes big output change
Hash Algorithm Types
-
security
MD5 (128-bit): Fast but cryptographically broken
-
security
SHA1 (160-bit): Deprecated for security use
-
security
SHA256 (256-bit): Secure and widely used
-
security
SHA512 (512-bit): Very secure, longer output
-
security
SHA3 Family: Latest standard, more secure
Security Warning:
MD5 and SHA1 are considered cryptographically insecure and should not be used for password storage or security-sensitive applications. Use SHA256 or stronger algorithms for security purposes.
