Generate MD5, SHA-1, SHA-256, and SHA-512 hashes from any text.
Hash Generator is a free online tool that generates MD5, SHA-1, SHA-256, and SHA-512 cryptographic hashes from any text input. Hashing is a one-way function that converts data into a fixed-length string of characters, used for data integrity verification, password storage, and digital signatures. The tool generates all four hash types simultaneously, allowing you to compare and choose the appropriate algorithm for your use case. MD5 produces a 128-bit hash (32 hex characters), SHA-1 produces 160 bits (40 hex characters), SHA-256 produces 256 bits (64 hex characters), and SHA-512 produces 512 bits (128 hex characters). Cryptographic hashing is fundamental to modern security. It's used for verifying file integrity (checksums), storing passwords securely, creating digital signatures, generating unique identifiers from data, and ensuring data hasn't been tampered with during transmission. Everything runs entirely in your browser using the Web Crypto API. Your text is never sent to any server, making it safe for hashing sensitive data like passwords, API keys, and personal information. There are no usage limits and no account required. Common use cases include generating checksums for file verification, creating password hashes for storage, verifying data integrity, generating content-based identifiers, and testing hash implementations in your applications. For stronger password hashing with salt and cost factors, use the Bcrypt Generator. For generating secure random passwords, try the Password Generator.
