SHA2 Hash Generator

This cryptographic utility generates hash digests using the SHA-2 family of algorithms including SHA-224, SHA-256, SHA-384, and SHA-512 variants. The tool leverages the Web Crypto API for secure client-side processing, producing hexadecimal-encoded outputs suitable for data integrity verification, digital signatures, and security applications. All four variants calculate simultaneously as you type, displaying results in real-time without network transmission.

The SHA-2 family was designed by the NSA and published by NIST as successors to SHA-1. SHA-256 produces 256-bit (32-byte) digests widely used in Bitcoin blockchain, SSL certificates, and countless security protocols. SHA-512 offers 512-bit output for applications requiring maximum cryptographic strength. The tool includes hash comparison functionality for verifying two hash strings match exactly, useful for file integrity checking or checksum validation.

Processing occurs entirely within your browser using native WebCrypto implementations, ensuring sensitive data never leaves your device. The interface displays all hash variants with one-click copying, making it easy to select the appropriate algorithm for your security requirements. Common applications include generating password hashes for storage, verifying downloaded file integrity, and creating unique identifiers for data deduplication.
