Hash Generator

Compute MD5, SHA-1, SHA-256, SHA-384, and SHA-512 cryptographic digests. Hashes are instantly generated locally in your browser.

Input String

Generated Hashes

MD5
SHA-1
SHA-256
SHA-384
SHA-512

Security Note: MD5 and SHA-1 are included for compatibility with legacy systems and checksums. They are cryptographically broken and are not safe for passwords or any security-sensitive use. Prefer SHA-256 or better for modern applications.

Cryptographic Hash Generator Online

A cryptographic hash function converts any input data into a fixed-size string of bytes (a digest). Our free online Hash Generator instantly computes the MD5, SHA-1, SHA-256, SHA-384, or SHA-512 hashes for any text you input. Perfect for verifying data integrity, comparing checksums, or creating unique identifiers.

Fast & Private: Input data is never sent to a server. This tool uses native browser APIs to compute hashes instantaneously and securely on your local device.

Core Features

  • Modern & Legacy AlgorithmsSupport for both secure modern hashing algorithms (SHA-256, SHA-512) and older legacy algorithms (MD5, SHA-1) that are still frequently used for checksums and basic integrity verification.
  • Hexadecimal & Base64 OutputsInstantly view the resulting digest in standard Hexadecimal format (commonly used for file checksums) or Base64 format (commonly used in web headers like Content-Security-Policy).
  • One-Way FunctionHashing is not encryption. It is computationally impossible to reverse a strong hash (like SHA-256) back into its original plaintext.

Frequently Asked Questions

Is hashing the same as encryption?
No. Encryption is a two-way function designed to be decrypted (reversed) using a password or key. Hashing is a one-way function. Once you hash a string (like a password), it cannot mathematically be turned back into the original string. It is primarily used to verify that data hasn't been altered.
Why are MD5 and SHA-1 considered insecure?
With the massive increase in computing power, algorithms like MD5 and SHA-1 are now vulnerable to "collision attacks". This means an attacker can create two different files that produce the exact same hash, allowing them to disguise malicious files as safe ones. You should always use SHA-256 or higher for security purposes.
