Frequently Asked Questions
What are the differences between hash algorithms?
MD5 outputs 128 bits and is fast but proven vulnerable to collisions; SHA-1 outputs 160 bits with lower security; SHA-256 and SHA-512 belong to the SHA-2 family with high security, recommended for security use.
Will my data be uploaded to a server?
No. All hash computation is done locally in your browser. Your text and file data never leave your device, fully protecting your privacy.
What input methods are supported?
Both text input and file upload are supported. Text input computes the hash in real time, while file upload generates a hash of the entire file content.
Can MD5 be used for password encryption?
Not recommended. MD5 is proven vulnerable to collisions and is unsuitable for password storage or other security scenarios. Use SHA-256 or stronger; for password storage, use a dedicated slow hash algorithm with a salt.
Does it support batch processing?
Currently it handles a single text or file at a time. For batch processing, enter text or select files one at a time.
Is this tool free to use?
Completely free. This is a pure frontend online tool - no registration required, no payment needed, just open and use.
