Frequently Asked Questions
No, all processing happens in your browser. Your data remains completely private and never leaves your device.
Different hash algorithms produce different length outputs and have different security properties. MD5 (128-bit) is fast but considered cryptographically broken. SHA-1 (160-bit) is also deprecated. SHA-2 family (SHA-256, SHA-512) are currently secure. SHA-3 is the newest standard. CRC32 is fast but not cryptographic.
Files up to 5MB work best for optimal performance. Very large files may take longer to process depending on your device’s capabilities.
Hash values are used for data integrity verification, password storage, digital signatures, and many other cryptographic applications. They produce a unique fingerprint for any input data.
