Frequently Asked Questions
Everything you need to know about processing files securely in your browser
Which hashing algorithms are supported by this generator?
This tool supports MD5, SHA-1, SHA-256, and SHA-512 algorithms. You can generate hashes from plain text inputs or directly from local files.
Can I securely hash files using this tool?
Yes. Files are processed entirely locally using the browser's FileReader API and cryptographic libraries. Large files are read incrementally without uploading them to any server, making file checksum verification fast and private.
What is a hash function used for?
Cryptographic hash functions take an input (text or file) and return a fixed-size string of characters, typically hexadecimal. They are commonly used for verifying data integrity (checksums), password storage, and digital signatures.
Is it possible to reverse a SHA-256 or MD5 hash?
Cryptographic hashes are designed to be one-way functions, meaning they cannot be reversed. However, weak algorithms like MD5 and SHA-1 are vulnerable to collision attacks and rainbow table lookups, whereas SHA-256 and SHA-512 remain highly secure.
