What is a hash function?

A hash function is a cryptographic algorithm that converts data of any size into a fixed-size string. It's a one-way process used for data integrity verification, password storage, and digital signatures.

Which hash algorithm should I use?

For security purposes, use SHA-256 or SHA-512. MD5 and SHA-1 are deprecated due to vulnerabilities. SHA-256 is recommended for most use cases, while SHA-512 provides maximum security.

Is my data safe when using this tool?

Yes! All hash generation happens 100% client-side in your browser. Your data never leaves your device, ensuring complete privacy and security.

Can I hash files with this tool?

Yes! Our hash generator supports both text and file hashing. You can upload files to generate checksums for data integrity verification.

A checksum is the hash value of a file, used to verify that the file hasn't been corrupted or tampered with during transmission or storage.

🔍 What is Hashing?

Hashing is a cryptographic function that converts data of any size into a fixed-size string. It's a one-way process - you can't reverse a hash to get the original data.
