Hash Generator (SHA-256, SHA-512, SHA-1, MD5)
Generate cryptographic checksums instantly from plain text or uploaded files using SHA-256, SHA-512, SHA-384, SHA-1, and MD5 hashing algorithms.
Code Snippets & Examples
Copy-paste ready code implementations for your project:
async function sha256(message) {
const msgUint8 = new TextEncoder().encode(message);
const hashBuffer = await crypto.subtle.digest('SHA-256', msgUint8);
const hashArray = Array.from(new Uint8Array(hashBuffer));
return hashArray.map(b => b.toString(16).padStart(2, '0')).join('');
}import hashlib
# Compute SHA-256
digest = hashlib.sha256(b'Hello World').hexdigest()
print(digest)echo -n "Hello World" | sha256sum⚡Related Developer Tools

Frequently Asked Questions
What is a cryptographic hash function?
A cryptographic hash function takes an arbitrary input string and produces a fixed-size, deterministic byte string (digest). It is a one-way function — given a hash, it is computationally impossible to invert back to the original text.
Is MD5 or SHA-1 safe for security?
No. MD5 and SHA-1 have known collision vulnerabilities and are considered broken for security applications. Use SHA-256, SHA-512, or Bcrypt for password hashing.
