Generate MD5, SHA-1, SHA-256, and SHA-512 hashes from text instantly.
A hash is a fixed-length string of characters generated from any input data using a mathematical algorithm. Hash functions are one-way functions, meaning you cannot reverse a hash back to the original input. They are widely used for data integrity verification, password storage, digital signatures, and security applications.
MD5: Produces a 128-bit hash (32 hex characters). Fast but cryptographically broken, not recommended for security purposes.
SHA-1: Produces a 160-bit hash (40 hex characters). Deprecated for cryptographic use due to collision vulnerabilities.
SHA-256: Produces a 256-bit hash (64 hex characters). Part of SHA-2 family, widely used in cryptography and blockchain.
SHA-512: Produces a 512-bit hash (128 hex characters). More secure than SHA-256, ideal for high-security applications.
Hashing is used to verify file integrity, protect passwords, create digital signatures, generate unique identifiers, and ensure data authenticity in blockchain and cryptographic systems.
