Hash Generator
Generate MD5, SHA-1, SHA-256, and SHA-512 hashes.
Enter text or select a file to generate hashes.
The Hash Generator computes cryptographic hash digests for any text or file input using industry-standard algorithms. It supports SHA-1, SHA-256, and SHA-512 via the browser's native Web Crypto API, ensuring fast and secure computation without any server round-trips.
Hashes are one-way functions: given the same input, they always produce the same fixed-length output, but you cannot reverse the process to recover the original data. Common uses include verifying file integrity, comparing data without exposing it, and generating unique identifiers.
SHA-1 (160-bit) is widely used but considered weak for security purposes. SHA-256 (256-bit) is the most common choice for modern applications, including Bitcoin and TLS certificates. SHA-512 (512-bit) provides the highest security margin and may be faster than SHA-256 on 64-bit processors.
