Frequently Asked Questions
What is a cryptographic hash function?
A hash function takes an arbitrary input string or binary file and maps it to a fixed-size string of bytes. It is a one-way mathematical function used to verify data integrity.
Are my files uploaded when generating hashes?
No. File buffer processing occurs 100% inside your browser using the native Web Crypto API and local client JavaScript libraries.
Which hash algorithm should I use for security?
SHA-256 and SHA-512 are recommended for modern security standards. MD5 and SHA-1 are included for checksum integrity verification of legacy software files.
