Frequently Asked Questions
Which hash algorithm should I use?
SHA-256 is recommended for most purposes. MD5 and SHA-1 are considered weak for security but useful for checksums.
Can hashes be reversed?
No, cryptographic hashes are one-way functions. You cannot retrieve the original text from a hash.
Is this processed securely?
Yes, all hashing happens locally in your browser. Your data never leaves your device.
