Base64 Encoder
Encode any text or string to Base64 format instantly.
Hash Generator
A secure, lightning-fast client-side hash generator. Create cryptographic hashes (MD5, SHA-1, SHA-256, SHA-384, SHA-512) from plain text or uploaded files. Features include real-time generation, file hashing without uploads, hash comparison, and lowercase/uppercase toggles. 100% private processing using the Web Crypto API.

What is the Hash Generator?
The Hash Generator takes any input (text strings or file binaries) and runs them through cryptographic algorithms to produce a fixed-length hexadecimal string (the hash).
How to Use
- Select whether you want to hash Text or a File.
- Type your text or drag-and-drop a file into the upload zone.
- The tool instantly generates the hash using the selected algorithm (MD5, SHA-1, SHA-256, SHA-384, SHA-512).
- Use the "Compare" field to verify if your hash matches an expected value.
- Copy or download the resulting hash directly.
Common Use Cases
- Verifying the integrity of a downloaded ISO or software package (checksum matching).
- Generating a SHA-256 hash for API authentication signatures.
- Testing password hashing mechanisms during local development.
Key Benefits
- Generates hashes instantly as you type.
- Supports large files securely in-browser via the File API.
- Provides a side-by-side comparison tool to easily verify checksums.
Frequently Asked Questions
Is this hash generator secure?
Yes. All hashing operations happen entirely within your browser using the native Web Crypto API. No text or files are ever sent to a server.
Can a hash be reversed?
No. Cryptographic hashes (like SHA-256) are one-way mathematical functions. They cannot be reversed to reveal the original input.
Why use MD5 if it is considered insecure?
While MD5 is cryptographically broken and shouldn't be used for passwords, it is still commonly used for simple file integrity checks (checksums) where malicious tampering is not a primary concern.
