SHA Hash Calculator

Overview

The SHA Hash Calculator is a comprehensive tool for computing SHA (Secure Hash Algorithm) hashes from text input or files. It supports multiple SHA variants including SHA-1, SHA-224, SHA-256, SHA-384, and SHA-512.

Features

• Multiple SHA Algorithms: Support for SHA-1, SHA-224, SHA-256, SHA-384, and SHA-512
• Text Input: Calculate hashes from any text input
• File Upload: Support for file upload with drag-and-drop functionality
• Output Formats: Choose between hexadecimal and Base64 output
• Text Encoding: Support for UTF-8, ASCII, and Latin-1 encoding
• Real-time Calculation: Instant hash calculation as you type
• History Tracking: Keep track of recent calculations
• Performance Metrics: Display processing time for calculations

Use Cases

• Data Integrity Verification: Verify file integrity using SHA hashes
• Password Storage: Generate secure hashes for password storage
• Digital Signatures: Create hash values for digital signature algorithms
• Blockchain Applications: Generate hashes for blockchain and cryptocurrency applications
• Security Auditing: Verify data integrity in security audits

Security Considerations

• SHA-1: No longer recommended for cryptographic purposes due to known vulnerabilities
• SHA-256: Currently the most widely used and recommended algorithm
• SHA-384/512: Provide higher security for applications requiring maximum protection
• SHA-224: Truncated version of SHA-256, suitable for specific use cases

The tool provides real-time feedback about the security level and recommendations for each algorithm.
