MD5 / SHA Generator

📘 How to Use MD5 / SHA Hash Generator

Simply type or paste any text into the input field. The hash value will be generated instantly for the selected algorithm (MD5, SHA-1, SHA-256, SHA-384, SHA-512). You can switch algorithms at any time — the output updates automatically. Use the Copy Hash button to copy the hash to your clipboard, and Clear All to reset both fields. All processing happens locally in your browser; your data never leaves your device.

🔢 What is MD5?

MD5 (Message Digest Algorithm 5) is a widely used cryptographic hash function that produces a 128-bit (16-byte) hash value, typically rendered as a 32-character hexadecimal number. It was designed for integrity checking but is now considered cryptographically broken and unsuitable for security-sensitive applications. However, it remains popular for checksums and non-critical fingerprinting.

🛡️ What is SHA (Secure Hash Algorithm)?

SHA is a family of cryptographic hash functions published by NIST. This tool supports SHA-1 (160-bit), SHA-256 (256-bit), SHA-384 (384-bit), and SHA-512 (512-bit). SHA-256 and SHA-512 are part of the SHA-2 family and are considered secure for most applications, including password storage, digital signatures, and blockchain technology.

⚖️ Differences Between Hash Algorithms

• MD5: 32 hex chars, fast but vulnerable to collision attacks. Suitable for non-security checksums.
• SHA-1: 40 hex chars, also considered weak; deprecated for security.
• SHA-256: 64 hex chars, strong and widely used in SSL/TLS, blockchain, and data integrity.
• SHA-384: 96 hex chars, truncated version of SHA-512 with better resistance to length extension attacks.
• SHA-512: 128 hex chars, highest security level, often used in high-security systems.

💡 Why Use a Hash Generator?

• Data Integrity: Verify that files or messages haven't been altered.
• Password Storage: Store hashed passwords instead of plain text (with salt).
• Digital Signatures: Hash is part of the signing process.
• Checksums: Quickly compare two strings or files.

📌 Example

⚠️ Security Note

MD5 and SHA-1 are no longer considered secure against deliberate collision attacks. For cryptographic security, always use SHA-256, SHA-384, or SHA-512. This tool does not store any input or output — all operations are performed client-side.
