Notes on File Hashing
- File hashing is performed entirely in your browser
- No files are uploaded to our servers
- Larger files may take longer to process
- For very large files, consider using SHA-256 for better performance
About Hash Comparison
- Compare hashes to verify file integrity or check password matches
- Use case insensitive comparison for hexadecimal hashes
- Use case sensitive comparison for base64 encoded hashes
- Two identical inputs will always produce identical hash values
Comparison Examples
Identical SHA-1 hashes
Similar SHA-1 hashes (different by one character)
Mixed case SHA-256 hashes
Security Note
- SHA-1 is no longer considered secure for cryptographic applications and should not be used for security purposes
- Use SHA-256 or stronger for secure applications
- All hash operations are performed locally in your browser
About SHA Hash Algorithms
- SHA-1: Produces a 160-bit (20-byte) hash value, commonly displayed as a 40-digit hexadecimal number
- SHA-256: Produces a 256-bit (32-byte) hash value, commonly displayed as a 64-digit hexadecimal number
- SHA-384: Produces a 384-bit (48-byte) hash value, commonly displayed as a 96-digit hexadecimal number
- SHA-512: Produces a 512-bit (64-byte) hash value, commonly displayed as a 128-digit hexadecimal number
- Hash algorithms are one-way functions - once data is hashed, it cannot be "unhashed"
- Hashes are commonly used for file integrity verification, password storage, and digital signatures
