Frequently Asked Questions
What is a hash generator used for?
It creates a unique, fixed-length string (checksum) from any input text. It's used for verifying data integrity, storing passwords securely, and digital signatures.
Which hashing algorithms do you support?
We support standard algorithms like MD5, SHA-1, SHA-256, SHA-512, and various SHA-3 variants.
Can a hash be reversed to original text?
No. Hashing is a one-way function. You cannot 'decrypt' a hash back to its original input string.
Is SHA-256 secure for passwords?
SHA-256 is a strong hashing algorithm, but for password storage, it's recommended to use it with 'Salting' or use specialized algorithms like Bcrypt.
What is a 'Collision' in hashing?
A collision occurs when two different inputs produce the exact same hash output. While rare, older algorithms like MD5 are now avoided due to collision vulnerabilities.
Is my text shared with any server for hashing?
No. All hash generation is performed locally in your browser using JavaScript libraries. Your sensitive data stays on your machine.
What is the difference between SHA-1 and SHA-256?
SHA-256 produces a longer hash (256 bits vs 160 bits) and is significantly more secure and resistant to modern cryptographic attacks.
Can I generate hashes for files?
Currently, our tool supports text-based input. File-based hashing is a planned feature for a future update.
Does the capitalization of the input affect the hash?
Yes. Hashing is extremely sensitive; even changing a single character's case or adding a space will result in a completely different hash.
Is there a limit to the input size?
For text, you can input very large strings. The generation takes a split second even for long documents.
