Hash Generator - SHA-256, SHA-512 & More
Generate SHA-1, SHA-256, SHA-384, and SHA-512 hashes securely in your browser. Uses Web Crypto API - your data never leaves your device.
What are SHA hashes?
SHA (Secure Hash Algorithm) creates a fixed-length fingerprint from any text input. SHA-256 is the most widely used for password hashing, data integrity verification, and digital signatures. This tool uses the Web Crypto API - your data never leaves your browser.
Supported algorithms are SHA-1, SHA-256 (the current security standard), SHA-384 and SHA-512. MD5 is not offered: it is broken for anything security related and the Web Crypto API does not implement it. Each algorithm has a different output length and security level.
All hash computations run entirely in your browser using the Web Crypto API. Your input data never leaves your device, making this tool safe for hashing sensitive information like passwords or API keys.
How the Hash Generator Works
- 01Enter or paste the text you want to hash
- 02Select the hash algorithm: SHA-1, SHA-256, SHA-384 or SHA-512, or all four at once
- 03The hash is computed instantly in your browser
- 04Copy the hash value for use in verification or storage
Understanding Hash Algorithms
Hash functions produce a fixed-length fingerprint of any input data. SHA-256 is the current standard for security applications like file integrity checks and digital signatures. MD5 and SHA-1 are considered broken for security purposes but are still used for checksums and non-security applications. Hashes are one-way - you cannot recover the original text from a hash.
When to Use a Hash Generator
Use a hash generator to verify file integrity (comparing checksums after downloads), create password hashes for secure storage, generate unique identifiers from data, and verify data integrity in API communications. Developers commonly use MD5 for checksums, SHA-256 for security applications, and HMAC for API authentication. Hash values are also used in blockchain technology, digital signatures, and version control systems like Git.
Common Use Cases
- Verify file integrity by comparing SHA-256 checksums after downloading software → Base64 Encoder & Decoder
- Generate password hashes for secure storage in databases and configuration files → Strong Password Generator
- Create content fingerprints to detect duplicate or modified documents
- Compute HMAC signatures for API authentication and webhook verification
- Generate SHA-256 checksums for cache-busting URLs in web development
Expert Tips
- Use SHA-256 for security applications - MD5 and SHA-1 are considered cryptographically broken and should only be used for non-security checksums
- For password storage, never use plain hashes - use specialized algorithms like bcrypt or Argon2 that add salt and are deliberately slow
- To verify a download, compute its SHA-256 hash and compare it character-by-character with the hash published on the download page
