Algorithm Information

SHA-256

SHA-256 is a cryptographic hash function that produces a 256-bit (32-byte) hash value. It's part of the SHA-2 family and is widely used for security applications and protocols.

Output Size: 256 bits
Security Level: High
Status: Recommended

Security Notice

SHA-1 and MD5 algorithms are cryptographically broken and should not be used for security-sensitive applications. Use SHA-256 or higher for new implementations.

Input Size: 0 bytes
Output Size: 0 bytes

How to Use Hash Generator

1

Input Your Data

Enter text to hash, upload a file, or paste content from your clipboard. The tool supports both text and binary data.

2

Choose Algorithm

Select from SHA-256 (recommended), SHA-512, SHA-384, SHA-1, or MD5. For security applications, use SHA-256 or higher.

3

Generate & Verify

Click "Generate Hash" to create the hash value. Copy the result for verification or use in security applications.

Key Features

  • Multiple Algorithms: Support for SHA-256, SHA-512, SHA-384, SHA-1, and MD5 with proper security warnings
  • File Hashing: Generate hashes for files of any size with efficient processing and progress tracking
  • Flexible Encoding: Output hashes in hexadecimal or Base64 format with case selection options
  • Salt Support: Add custom salt values for enhanced security in password hashing scenarios

Common Use Cases

Data Integrity

Verify that files haven't been corrupted or tampered with during download or transfer.

Password Storage

Hash passwords before storing them in databases (with proper salting and iterations).

Duplicate Detection

Identify duplicate files by comparing their hash values instead of file names.

Digital Signatures

Create digital fingerprints of documents for authentication and non-repudiation.
